Exploration on Éléonore Gold project, Québec

Posted by on Friday, 14 March, 2014

Midland Exploration Inc.  reports the beginning of its exploration activity on its 100% owned James Bay Éléonore Gold project located in James Bay, Québec. The first phase of the 2014 exploration program consists of a helicopter airborne magnetic geophysical survey over the Éléonore Centre property.

The Eléonore project, which encompasses the Éléonore Centre and West properties, is constituted of a total of 247 claims covering 128 square kilometres, and is located approximately 30 kilometres southwest from and in a geological environment similar to Goldcorp Inc.’s Éléonore deposit. This world-class gold deposit contains reserves of 4.03 Moz Au (proven and probable categories), combined measured and indicated resources of 4.84 Moz Au and inferred resources estimated at 4.10 Moz Au. (Source: Goldcorp press release dated February 13, 2014).

Prospecting conducted by Midland from 2009 to 2013 on the Éléonore Centre property identified the presence of several gold showings associated with quartz-tourmaline pyrite bearing veinlets occurring in sheared metasediments, as well as mafic and felsic metavolcanics which returned up to 18.8 g/t Au. These results strongly suggest that an auriferous hydrothermal system is present on the property by a strong abundance of quartz-tourmaline veins over a plurimetric area. In addition, the 2013 ground induced polarisation (“IP”) survey identified many north-south trending IP anomalies and several remain unexplained. The 2011 soil geochemistry survey permitted to delineate a series of As-Cu-Sb anomalies clustered along a north-south-trending axis. Finally, a series of parallel northeast trending AeroTEM II conductors were outlined by the 2010 airborne geophysical survey which targeted sulfide bearing Éléonore-type sediments on the northern part of the Éléonore Centre property. Some of these conductors coincide with uncovered gold-bearing disseminated to semi-massive sulfides zones identified by Midland and several EM anomalies still remain unexplained.

A high definition airborne magnetic survey covering the Éléonore Centre property was just completed, including the area covered by the 2013 IP survey. The results and interpretation of this survey, totalizing 386 linear kilometres, are pending. Furthermore, preparation for the upcoming 2014 summer exploration program on the Éléonore Centre property currently underway.


  • The Eleonore property is located about 450 kilometres north of the town of Matagami, in the Opinaca Reservoir area, James Bay, Quebec.


  • The Eleonore property consists of two claim blocks (Centre and West). The Centre Block consists of 121 claims covering a surface area of about 63 square kilometres, whereas the West Block consists of 109 claims covering about 57 square kilometres. The two blocks are located about 30 kilometres southwest of the Roberto deposit on the Eleonore property held by Goldcorp, where measured and indicated resources are estimated at 3.15 million ounces of gold and inferred resources at 6.25 million ounces of gold.


  • Covers a major N-S-trending structure between metasedimentary rocks and metavolcanic rocks interpreted as the extension of the structure occurring near the Eleonore gold deposit.
  • Prospecting work has uncovered many new gold showings associated with metasedimentary rocks (conglomerates and greywackes):
    • Golden Gun showing: 18.8 g/t Au, 13.6 g/t Au, 0.76 g/t Au
    • Golden Gun West showing : 1.69 g/t Au
    • Aston Martin showing : 1.63 g/t Au
    • Gold Finger showing: 1.01 g/t Au, 0.82 g/t Au
    • Golden Eye showing: 1.90 g/t Au, 0.90 g/t Au
    • Casino showing: 0.76 g/t Au, 0.64 g/t Au
  • Located along a regional metamorphic gradient, typical of the contact between the La Grande and Opinaca groups.
  • New soil (humus) geochemistry anomalies identified in the south part of the Eleonore Centre Block.

Coincident Geochemical and Geophysical Data Pinpoints Drill Targets, Greyhound, Nunavut

Posted by on Saturday, 1 March, 2014

Aura Silver Resources Inc. announces the results of a comprehensive report completed by L.E Reed Geophysical Consultant Inc. (“Reed”) which supports, from a geophysical standpoint, drill targets established geochemically by Activation Laboratories Ltd. (Actlabs) Spatiotemporal Geochemical Hydrocarbon (“SGH”) technology for the Aura Lake area as well as the Dingo prospect north-west of Aura Lake, both part of the Greyhound Project, NU.

As reported by Reed, “Correlations between the geochemistry and various geophysical data suggest support for the possible identification of gold and silver deposits at Aura Lake and a gold and copper deposit at Dingo”. This report may be accessed at the Company’s web-site ( under the section Projects / Canada.

The potential sources of high-grade gold boulders (up to 28 g/t) and high-grade silver (up to 5,300 g/t) have been identified in close proximity to Aura Lake. The gold and copper targets at the Dingo prospect area north-west of Aura Lake are surface showings. New interpretation of geophysical data and SGH has refined the drill targets. This geophysical analysis has identified multiple structures/contacts with the use of three-dimensional inversion imagery of airborne VTEM EM and magnetic responses and ground Induced Polarization and Resistivity data. These structures/contacts at Aura Lake may have provided a pathway for fluids carrying mineralization and are interpreted to support the drill targets originally defined by geochemical analysis.

Robert Boaz CEO and President of Aura Silver states that, “The detailed geophysics analysis undertaken by Reed gives us further comfort that we are zeroing in on the source of high-grade surface gold, silver and copper mineralization. Despite the difficult market for all junior exploration companies we continue to enhance the value of our properties.”

During the fall of 2006, an airborne MEGATEM® geophysical survey was flown on the initial property by Fugro Airborne Surveys Corp. In 2007, further prospecting of MEGATEM anomalies took place. Samples collected in 2007 contained up to 2.4% zinc (Zn), 1.02% copper (Cu), 8.1% lead (Pb), 10g/t gold (Au) and 51 g/t silver (Ag) highlighting the potential for discovery of VMS (volcanogenic massive sulphide) ores.

During 2008, Fugro completed the flying of a GEOTEM® survey over the new Greyhound claim group. Results from this survey were utilized in an on-the-ground field program to complete geological mapping and sampling. Samples prospected during 2008 contained up to 4.1% Cu, 13.4% Zn, 8% Pb, 2,700 g/t Ag and 28g/t Au and to the northeast of Aura Lake a series of boulders contained up to 18.5% Zn and 9.2% Cu.

In late 2009, a high precision VTEM® helicopter borne electro-magnetic survey was completed.

IP survey at a project in the Dominican Republic

Posted by on Tuesday, 18 February, 2014

Precipitate Gold Corp.  announces it has initiated a ground Induced Polarization (“IP”) geophysical survey at the Company’s 100% owned Juan de Herrera project in the Dominican Republic.

Insight Geophysics Inc. (“Insight”) has been contracted to conduct the survey and crews have commenced grid line cutting and ground preparations in advance of the project’s maiden geophysical survey. Crews will establish a control grid over the project’s Ginger Ridge Zone, where the Company’s previous surface work outlined a gold-rich geochemical anomaly measuring 1,000 metres by 400 metres and yielded highlight rock grab sample values up to 11.8 grams per tonne (“g/t”) gold and 100 g/t silver, as well as a 13.0 metre continuous channel sample that returned 1.5 g/t gold and 20 g/t silver, open in both directions.

Precipitate’s President & CEO, Jeffrey Wilson stated “We’re excited to commence this program, as induced polarization geophysical surveying has proven to be an effective exploration technique at other projects within the Tireo volcanic belt. It was an important targeting tool at other notable recent discoveries within the Tireo belt, particularly those of GoldQuest Mining and Unigold Inc. We’re pleased to be working with Insight on this important next phase of exploration work at our Juan de Herrera concession, as its local experience and expertise offers Precipitate an advantage in data compilation aimed at identifying anomalies and delineating possible drill targets.”

Insight’s IP survey will measure the relative chargeability and resistivity of underlying rock and highlight areas that may contain higher sulphide and/or resistive silica concentrations. Previous work in the Tireo belt, by Insight and others confirmed a correlation between high chargeability and sulphide mineralization at the Romero and Candelones discoveries. The attached map shows the approximate outline of the proposed grid to be emplaced in relation to existing soil geochemical anomalies and grab/channel sample results at Ginger Ridge. IP surveying will start near the centre of the grid and can be expanded based on interpretation of results as they are generated. The survey is expected to provide a greater understanding of the subsurface mineralization and geometry and assist in prioritizing targets for follow up trenching and/or a first-phase drill program.

IP data analysis at copper-gold project in Mongolia

Posted by on Monday, 10 February, 2014

Kincora Copper Limited  provides an overview on an internal interpretations of last years exploration programme at Kincora’s flagship Bronze Fox license (Oyu Tolgoi South Gobi porphyry copper belt in southeast Mongolia) having integrated them with previous geology and geophysical results. This follows the recent receipt of positive findings from three independent consultants, further reinforcing an independent groups’ technical review late 2012, advancing and refining multiple bulk tonnage copper porphyry targets.

Some of the Key findings include:

  • Previous results coincident with lower priority Induced Polarization (IP) chargeability anomalies supporting IP being an effective exploration tool
  • Multiple large-scale copper porphyry targets with favourable geology and geophysics drill ready supporting the possibility of bulk tonnage ore mineralization in “finger type” porphyries similar to Oyu Tolgoi or Northparkes in New South Wales
  • Happy Geo prospect has emerged as an attractive, earlier stage, at or near surface follow up exploration target, plus the potential for porphyry targets at depth









Commenting on today’s announcement, Sam Spring, President and CEO of Kincora, said:

“Internally we are very pleased because drilling in late 2012 was extremely encouraging with localized higher grade, for example over 4% copper in our last hole, and broad lower grade intersections, including at least 800m @ +0.40% CuEq, with 37m @ +1% CuEq, in an earlier hole. Our 2013 field season deployed some of the same wide ranging and detailed exploration techniques used at Oyu Tolgoi to significantly increase the confidence in high priority, and large scale targets that demonstrated exceptional corresponding prospectivity. Last years’ activities, independent consultants analysis and discussions with various industry groups have assisted to “explain” previous results, convincingly prove a fertility signature for copper porphyries and in de-risking multiple drill ready targets.

Considering the size of the anomalies and advance stage of target areas, two key attractions and relatively unique characteristics of Bronze Fox, successful proof of concept activities in 2014 could provide visibility of significant copper-gold resource potential of Oyu Tolgoi or finger style copper porphyries. While earlier stage, the Happy Geo prospect has too emerged as an attractive exploration target, reinforcing that Bronze Fox continues to look better as more activities are undertaken. Kincora is persisting with additional measures to add shareholder value and is encouraged by initial, and further proposed, reform to the Mongolian mineral sectors legislative environment, amongst other efforts to provide additional advantages to the private sector.”










Copper-gold porphyry targets refined and de-risked

Since 2010, Kincora has undertaken soil geochemistry, Vector IP and some sections of DDIP, ground magnetic surveys, and drilled a further 70 holes inside of the Bronze Fox license area. Drilling has expanded the known mineralization footprint to about 40km2, remaining open, confirming porphyry style of copper-gold resource potential with extensive lower grade intersections from at or near surface and proven to 1,360 metres. Results of the last drilling programme, in late 2012 were extremely encouraging with a number of porphyry intersections confirming the potential for a high-grade deposit (localized +4% Cu in our last hole – F72 – drilled into a new target area based upon then recent IP analysis) with broad lower grade (eg +800m @ +0.40%CuEq, including 37m @ greater than 1% CuEq – F62) intersections.

Previous geology and geophysics supported the potential of a copper-gold resource. Indeed early stage studies had commenced on a potentially small scale near production heap-leach SX-EW operation utilising near surface oxide mineralization, and deeper drilling results at the end of the 2012 confirmed the potential for high-grade copper porphyry mineralization. However, the lack of IP data below 400 metres depth, and only in certain areas, limited the ability to reconcile previous drilling and indications of significant scale hydrothermal fluids that support potential concealed higher grade copper porphyry mineralization. Given the limited zones of outcropping primary mineralization, known regional (block) faulting and target of Oyu Tolgoi (‘OT’) or finger porphyry style copper systems, Induced Polarization, coupled with existing magnetics, has been proven to be an effective exploration tool when integrated with proper geological information and interpretation. The success of similar IP programmes at OT and the technical successes experienced by Kincora in late 2012, with drilling at previous IP anomalies returning alteration, sulfides and copper mineralization (+4% localized copper intersection in F72), adds significant substance to IP analysis particularly given existing geological data available at Bronze Fox, which is one of the most advance copper exploration projects in Mongolia.

OT style mineralization generally features relatively narrow (comparing with North and South American porphyries), long strike orebodies, and good extension to depth. As such, the Search IP system, utilized in the 2013 IP survey, which has penetrated to over 800m to 1000m, was selected as the optimal tool to assist locating the mineralization or alteration zone with disseminated sulfides (which is normal for porphyry mineralization) with good extension to depth which may indicate disseminated pyrite/sulfides channels, and support the possibility of ore mineralization based on the comparison of previous drilling results and the distribution of the IP chargeability anomalies. It is thought that those mineralization or alteration zones with good extension to depth have a better chance to host higher-grade mineralization, and economic orebodies.

At Bronze Fox, the 2013 IP analysis illustrates that prior drilling failed to adequately test most large chargeability high anomalies with previous encountered mineralization coincident with lower priority IP chargeability zones. Prior to the 2013 programme earlier geophysics could not provide an adequate guide for either depth extension potential of identified mineralized zones nor for targets below 400m below surface, with drilling being largely lead from encouraging mineralization encountered in previous core. For example the aforementioned holes, F62 and F72, illustrate the grade of CuEq and IP chargeability co-relationship, which support that high chargeability is coincident with sulfides of mineralization zones. The new IP results coupled with the latest alteration and veining studies have “explained” previous results, particularly the extensive 0.20 to +0.30% copper intersections to date, and lead to a reinterpretation and refinement of targets. In F62, over 800m graded at least 0.4% CuEq with subsequent IP analysis indicating the hole only interested the periphery of a relatively weak anomaly target (noting higher grades, including 37m @ +1%CuEq, were coincident with being within less than 500m from the interpreted IP anomaly zone) and subsequent alteration and veining studies indicate a less prospective portion of the interpreted porphyry system. The application of the 2013 Search IP programme, coupled with existing geology and geophysics, and independent analysis undertaken by Professor Tony Crawford and Plus Minerals (Imants Kavalieris) has advanced and refined target generation.

A number of analogies between the current stage of exploration and results at Bronze Fox and Oyu Tolgoi pre “discovery hole” have emerged after our 2013 field season, including geophysical anomalies remaining largely untested with favourable mineralization coincident nearer surface and lower priority IP targets. At Oyu Tolgoi, previous BHP and Ivanhoe drilling failed to reach the geophysical targets, with a change in exploration approach to test the geophysical and hypogene potential resulting in OTD 150, between previous shallow holes (BHP 9 and BHP 10), being the first ‘deep’ hole and credited as the “discovery hole”.

At Bronze Fox nine drilling target zones have been identified following the latest IP survey results being integrated with geology, soil geochemistry, rock chip assay result, ground magnetic survey and historical drilling results. IP survey results illustrate multiple significant strike (+1-2km) chargeability high anomalies with good extension to depth that may indicate disseminated pyrite/sulfides channels.

Two targets of particular note are:

  • Sophie North – a classical geophysical circular feature ~2km x 3km from an estimated ~300-500m depth to +900m. Previous drilling failed to enter IP target zones but returned anomalous copper and gold mineralisation (holes lost in an alteration zone).
  • Eastern West Kasulu/Leca Pass – Numerous holes close to IP targets have returned favourable grades but have failed to test the target zone. Multiple specific +1-1.5km anomalies targeted for potential drilling with regional scout holes and geology providing favourable results.

Successful “proof of concept” activities at the identified targets, including Sophie North and Eastern West Kasulu/Leca Pass, with economic grade (or high grade) intersections, could support a significant copper ore resource. Collectively there is large-scale copper-gold resource potential which is one of the underlying attractions of Bronze Fox. Previous phases of exploration have been favourable, refined and de-risked target generation, and while there is no certainty of exploration success, numerous drill ready targets have been defined, with few other activities that could meaningfully further de-risk these targets (ex-Happy Geo, discussed further below) based on previous experience at Bronze Fox and other porphyry exploration projects.

Happy Geo prospect

Following the very high and large chargeability anomalies identified by the Search IP surveyed in 2013 and 3D IP undertaken in 2012, a further 68 rock samples were collected in late 2013 from various alteration zones focused around the Happy Geo prospect. This region is a relatively early stage exploration area, activities really only commenced in 2013. Favourable soil and rock chip samples, with good gold anomalies and outcrop, were returned during the 2012 and 2103 field seasons. Plus Minerals’ short wave infra-red (SWIR) spectrometer analysis of the 68 recent samples confirmed zones of argillic, sericitic and and silicification alteration with pyrite coincident with the IP chargeability anomalies. The SWIR analysis indicates alteration maybe related to an underlying porphyry system but further analysis is planned and required to confirm this.

Further integration of data and analysis on this area is ongoing and while early stage, and very different to the more advanced northern targets, it could indicated some additional resource potential besides the known copper potential areas in Sophie North, West Kasulu, Leca Pass etc. Two zones of outcrop, both with at least a 1-1.5km strike, have been identified at Happy Geo with rock chip samples of up to 91g/t gold.

Geophysical Survey at Las Morras Project (Spain)

Posted by on Friday, 20 December, 2013

Emerita Gold Corp.  announces the completion of geophysical exploration programs at its 100% owned Las Morras Property in the Extremadura Region of western Spain. The geophysical surveys consisted of Very Low Frequency (VLF), Induced Polarization (IP) and Electrical Resistivity Tomagraphy (ERT) surveys over the Central and Northwest target areas. The surveys identified several anomalies that are interpreted to represent shear zone structures coincident with the previously identified gold geochemical anomalies (see news releases dated August 29 and April 8, 2013). These interpreted structures will be evaluated as potential bedrock sources for the gold identified in the soils over the geophysical features by trenching and, if appropriate, drilling.


As previously reported, geochemical surveys have identified two areas with strong gold anomalies referred to as the Central and the Northwestern areas . In the Central area two gold geochemical anomalies have been identified, both approximately 300 meters wide and extending in an east-west direction 500 meters and 800 meters, respectively. These anomalies extend beyond the survey limits to the east and also to the west (see press release dated April 8, 2013).

The Northwestern area is characterized by a single gold anomaly (Figure 3) that extends approximately 700 meters long and over 100 meters wide in an east-west direction. This anomaly also extends beyond the limits of the survey area to the west and to the east (see press release dated August 29, 2013).

Geological mapping indicates that these gold anomalies are underlain by zones of strong shearing in bedrock. The shear zones are developed within the Precambrian Schist-Greywacke Complex (SGC) and are characterized by a zone of high strain and local quartz-gold veining, with predominantly a east-west direction. Outcrop is limited and the geophysical surveys are designed to improve the targeting of the follow up program.

Geophysical Surveys

Geophysical surveys (VLF, IP and ERT) were carried out during October and November 2013, with interpretation completed in mid December, to identify geophysical anomalies representative of bedrock structures potentially related to mineral occurrences. The surveying was performed in both, the Northwestern area and the Central area.

Survey Results

The VLF survey consisted of 27 linear kilometres in both the Northwestern and Central areas, where measurements were performed every 10 meters. As shown in Figure 4, in the Northwestern area 8.9 linear kilometres were surveyed on 14 lines oriented north-south, with lines ranging from 350 to 1,100 meters each. In the Central area 18.1 linear kilometres were surveyed on 20 lines with north-south orientation and lines ranging from 550 to 1,100 meters each (Figure 6). The spacing between lines was determined according to the results of the geochemical campaign (see press release dated August 29, 2013), ranging from 50 to 100 meters.

The IP and ERT surveys consisted of 10.4 linear kilometres in both the Northwestern and Central areas. Both the IP and ERT surveys were measured simultaneously with the same device. The spacing between electrodes was 10 meters, which allows detection of features up to 120 meters depth. Figure 5 shows the distribution of the 11 lines of the IP and ERT surveys for the Central area, where 6.93 linear kilometres were surveyed. All lines were 630 meters in length oriented in north-south direction excepting one line with an east-northeast orientation. In the Northwestern area 5 lines were measured by IP and ERT, for 3.47 linear kilometres. The lines varied in length, from 630 to 950 meters. The spacing between lines was determined based on the results of the geochemical campaign (see press release dated August 29, 2013), ranging from 100 to 450 meters.

VLF and ERT-IP images/profiles clearly indicate several subvertical anomalous geophysical zones, characterized by resistivity-chargeability highs (i.e. 300-5,000 Ωm, and >150 ms) (Figure 6).

Geophysical Survey Interpretation

The VLF survey showed conductive anomalies in both the Northwestern and Central areas which have a predominantly east-west orientation. However, some alignments of northwest- southeast direction have also been identified. These VLF anomalies correspond to fault orientations seen in mapping and with the geochemical data.

The IP and ERT surveys allowed the identification of bodies and zones with high chargeability values in the case of IP and high/low resistivity values in the case of ERT. The survey identified bodies with a broad east-west orientation in both the Northwestern and Central areas, which are coincident with the VLF results.

The geophysical data, together with geologic information and geochemical data from the two target areas, identified features having characteristics that would be expected from a shear zone system. This shear zone system is interpreted to represent a possible source of the gold found in the area and will be the focus for follow up trenching and, if merited, drilling. The geophysical anomalies are coincident with geochemical anomalies found in the central and northwest areas. Furthermore, both the geochemical and geophysical anomalies are open along their strike, particularly to the east. The extent of the anomalous body in the Central target area, based on the geochemical and geophysical results, is 1,200 meters long, 90 meters wide with an extension to a depth of at least 120 meters based on the IP/IRT, corresponding to the bottom of the geophysical profiles. In the Northwestern target area the anomalous body is 600 meters long, 80 meters wide and continues to a depth of 100 meters, corresponding to the bottom of the geophysical profiles.

The identification of geophysical anomalous areas (i.e., faults zones and bodies of high resistivity and high chargeability) represent the prospective targets for trenching and drilling.

Survey Methods

Both electromagnetic (EM) and DC-geoelectrical methods were selected to perform the survey. These methods are well-known to be suitable for cost-effectively identifying geophysical characteristics for geological features such as shear zones with low sulphide mineral concentrations. The selected techniques were Very Low Frequency (VLF) (Klein and Lajoie, 1980), Electrical Resistivity Imaging (ERI) (Griffiths and Barker, 1993) and Induced Polarization (IP) (Keller and Frischknecht, 1966).

The VLF measuring was carried out with an ENVI system (Scintrex) equipped with a VLF sensor module. The VLF sensor consists of three orthogonal coils designed to make it an omni- directional system.

The acquiring system for the ERT-IP was a Terrameter LS resistivimeter (ABEM SE) with 12 channels and 250 W Tx ouput. The array was implemented by 4 multicore reels of 16 take-outs each, steel electrodes and connections, up to 64 electrode configuration system.

Geophysical Survey Defines Large Scale Targets at Suriloma Gold-Silver Project, Peru

Posted by on Monday, 28 October, 2013

Darwin Resources Corp. has announced that it has commenced a ground geophysical induced polarization (“IP”) survey at its Suriloma project in the Department of La Libertad, Peru. Suriloma is located in a pedigreed epithermal gold belt, just 30km from Barrick’s Lagunas Norte (14 Moz contained gold) and 50km from Rio Alto’s La Arena mine (2.3 Moz gold oxide). Now the company reports results from a dipole-dipole induced polarization (“IP”) geophysical survey at the project in Peru.

Key points:

   -- The survey highlighted a number of strong geophysical anomalies that
      support the interpretation that recent diamond drilling intersected the
      upper, low-temperature part of an epithermal vein system and point toward
      a number of large-scale untested gold and copper targets at depth; 

   -- At the La Puerta area, an IP anomaly has been defined over 1300 metres by
      200 metres, extending from a depth of 200 metres to the limit of the
      survey depth at 300 metres depth. The anomaly is interpreted to be the
      disseminated sulphidic core to the gold mineralization observed in
      shallow drilling; 

   -- At the Edelmira area located 4 kilometres to the west of La Puerta, an IP
      anomaly has been mapped over an area of 400 by 300 metres open to the
      west. The anomaly is located at 250 metres depth and is interpreted to
      reflect the upper parts of a buried porphyry copper system.

Dr Graham Carman, President and CEO, states: “The IP survey has confirmed the presence of large-scale chargeable targets that lie immediately beneath the gold-bearing structures drilled 2 months ago. The survey has significantly increased the prospectivity of the area and we look forward to drill testing these exciting epithermal gold and porphyry copper targets.”

In total, 19.1 line-kilometres of dipole-dipole IP were surveyed on two separate grids, including at the La Puerta area where the Company previously reported encouraging gold intersections in several shallow drill holes, including 13.1 metres @ 1.4 g/t gold from 50.8 metres from hole SU-003 and 14.7 metres @ 0.9 g/t gold from 123.2 metres in hole SU-011 (see Darwin Press Release August 19 2013). Modelling of the IP survey at La Puerta shows a steeply north-dipping tabular zone of conductive rocks up to 200 metres wide, which is interpreted to be the down-dip continuation of clay altered volcanic rocks associated with outcropping epithermal veins. At the base of the conductive zone a chargeability anomaly has been mapped over 1300 metres by 200 metres, extending from a depth of 200 metres to the limit of the IP model at 300 metres depth from surface (Figures 2 and 3). It is interpreted that the chargeability anomaly reflects sulphide mineralization at or near the contact with quartzite metasediments lying beneath the younger andesite volcanics. This is a high-priority drill target. The quartzite sediments are the preferred host rocks at large gold deposits elsewhere in the La Libertad region of Peru. Earlier drilling at La Puerta tested part of the epithermal vein system down to an average depth of only 65 metres and did not drill to sufficient depth to intersect the chargeable anomaly identified in the IP survey.

An extension of the IP survey 4 kilometres to the west at the Edelmira area defined a chargeability anomaly at a depth of 250 metres, which has dimensions of 400 by 300 metres and remains open to the west. This chargeability anomaly lies immediately beneath outcrops of copper-silver-gold bearing veins with quartz-sericite alteration, and is interpreted to reflect the upper parts of a buried porphyry copper system based on the Company’s experience elsewhere in Peru.

Ground Geophysical Survey at Suriloma, Peru

Posted by on Wednesday, 16 October, 2013

Darwin Resources Corp. announces that it has commenced a ground geophysical induced polarization (“IP”) survey at its Suriloma project in the Department of La Libertad, Peru. Suriloma is located in a pedigreed epithermal gold belt, just 30km from Barrick’s Lagunas Norte (14 Moz contained gold) and 50km from Rio Alto’s La Arena mine (2.3 Moz gold oxide).

At Suriloma, Darwin has discovered surface gold and silver mineralization at 6 prospect areas over a strike length of 5 kilometres. Only one of these areas, La Puerta, has been partially drill tested by drilling to a maximum depth of 100 metres in August 2013. Encouraging gold was intersected in several drill holes with gold grades increasing with depth at La Puerta (see Darwin Press Release August 19 2013).

Gold mineralization occurs together with disseminated sulphides, which should be detectable in the sub-surface using IP geophysics. Two separate areas will be surveyed with IP, which will help identify new targets for future drill testing from the surface to a depth of 300 metres. Gold targets at the La Puerta – Inmaculada – Guadalupe areas will be covered by one survey, while a copper – silver target will be tested by a second survey area at Edelmira.


Dr Graham Carman, the Company’s President and CEO, states: “Suriloma is a large project with multiple mineralized structures identified through mapping, surface sampling and early stage drilling. The project warrants the momentum of further exploration and we look forward to receiving the geophysical data which will aid in refining and extending targets down to a maximum depth of 300 metres for our next drill program. We expect the IP program to be completed before the end of October.”

Red Pine Exploration Inc.  has recently completed an IP survey and second phase bedrock sampling program over its Cayenne-Chili Property. The Cayenne-Chili Property consists of 24 contiguous mining claims and patents totalling 3900 hectares.  The claims sit in a region interpreted as the western extension of both the Larder-Cadillac deformation zone and the second a western extension from the Porcupine-Destor deformation zone to the north.

New VMS Occurrences Discovered

The initial prospecting, mapping and channel sampling program completed in July, 2013 across the property returned numerous, significant polymetallic assay values that are characteristic of a volcanogenic massive sulphide (VMS) mineralized system.  The program identified an extensive alteration system with sodium depletion and chlorite enrichment, a geochemical assemblage characteristic of a VMS system.  The second round of bedrock sampling was designed to augment the newly discovered anomalous zones.

‘New Zone C’ reported highly anomalous values of 24.7% zinc, 15.6% lead and 1.1% copper. These values are similar to those reported on the historical exploration on the nearby ‘Jefferson Deposit’[1], with the exception of the highly anomalous copper (Cu) values. The historical (1950’s) results intersected 4.43% Zn and 1.25% Pb over 22.9m and 9.1% Zn and 11.5% Pb over 6.9m, but no appreciable copper. In the 1980’s work by Falconbridge encountered 2.7% Zn over 9.12m and 1.6% Zn over 13.83m, with another hole reporting 1.7% Zn over 17.2m. The newly identified copper mineralization leads Company geoscientists to believe that a ‘heat vector’ towards the source of the mineralization can now be established.

Quentin Yarie, president and COO commented:” It is promising to find high grade mineralization beyond the historic showings which complements the current geophysical interpretation.  The alteration and VMS mineralization observed at surface is much more extensive than we had believed based on our review of the previous exploration programs.  We also have a high priority geophysical target immediately north of the sodium (Na) depleted footwall materials – a setting similar to Sturgeon Lake”.

IP&VLF surveys for gold in Central Yukon

BCGold Corp. announces that exploration work has commenced on its 100%-owned WS Property  in central Yukon. The Property is situated adjacent and along strike with Copper North Mining Corp.’s Carmacks Copper Project (the “Carmacks Project”), which has Proven and Probable Reserves of 11.5 million tonnes grading 0.98% total copper, 0.44 g/t gold and 4.3 g/t silver and is in the final stages of mine permitting.
The WS exploration program, partly funded by a $25,000 Yukon Mining Incentives Program (YMIP) grant, is designed to enhance current drill targets on the Property, which are interpreted to be the strike extents of Zones 12 and 14 of the Carmacks Project. Previous drill testing by BCGold intersected two near-surface copper sulphide horizons averaging 0.17% Cu over 63.1 metres (see January 13, 2009 news release). The 2013 exploration program will consist of the following:
  • detailed high-resolution IP geophysics near the claim boundary of the Carmacks Project and the Property;
  • a limited program of VLF geophysics and biogeochemical sampling, as alternative techniques to delineate further the strike extent of Zones 12, 14 and the ICE showing;
  • geological mapping and prospecting over a 2.5 km2 prospective area with IP and magnetic signatures and elevated copper-in-soil anomalies that are suggestive of near-surface, Minto-style mineralization.
BCGold’s 2013 exploration program will take approximately four weeks to complete. The IP geophysics program is being conducted by GroundTruth Exploration based in Dawson, Yukon. The concurrent VLF geophysics and biochemical sampling programs are being conducted by Dumas Consulting and Core Assets Consulting, both independent contractors to the Company. Biogeochemical samples will be submitted to Activation Laboratories Ltd. in Kamloops, British Columbia, an ISO 9001:2008 accredited laboratory.

The Targets

All of the Minto/Carmacks Copper-Gold properties were staked over areas with geological, geochemical and geophysical characteristics known to reflect near surface, high-grade, structurally controlled copper-gold mineralization in the region, such as the Minto and Carmacks copper-gold deposits.

BCGold Corp. is focused on the discovery of stand-alone and/or satellite copper-gold deposits, the latter of which could be used to supplement mill feed for the Minto and future Carmacks mining operations.

Nearby Deposits


Capstone Mining Corp.’s Minto Mine is a 3,600 tonne per day, conventional crush and flotation, open pit mining operation that produces copper concentrates with significant gold and silver credits. It is one of the highest grade open pit copper-gold mines in the world. Capstone continues to develop its resources and find significant new deposits in the area.


Copper North Mining Corp.’s Carmacks Copper Project has an NI 43-101 compliant Proven and Probable Reserve estimate of 10.6 million tonnes at 1.044% total copper, 0.484 g/t gold and 4.62 g/t silver. Copper North plans to construct an open pit mine with an acid heap leach and solvent extraction/electrowinning (SX/EW) process facility and is in the process of obtaining the final permitting requirement for mine operations, a Water Use License.

Results from Spring Exploration on Ring of Fire

Posted by on Friday, 9 August, 2013

MacDonald Mines Exploration has received the results from its Spring 2013 drill program targeting volcanogenic massive sulfides (“VMS”) in the Ring of Fire (“ROF”).

The history of geophysical investigation of the property can be found here.

Two drill targets were tested during the program over the Butler 3 and Butler 4 targets respectively. The Butler 3 drilling did not hit appreciable copper or zinc mineralization, but did intersect hydrothermally altered felsic and intermediate volcanic rocks that are indicative that the drill holes are proximal to a large VMS body. The Butler 4 drilling intersected copper and zinc mineralization that Company geoscientists believe to be associated with stratabound mineralization that extends to depth.

“MacDonald is keenly aware that the market, especially today, is only motivated by huge success. James Bay exploration is tough, it is a wetland with little outcrop. Consequently we must utilize drill results for ongoing quantification that further exploration is warranted. The Butler 3 and Butler 4 targets have all the necessary components for discovery:

  • A large heat source (ultramafics, proven komatiates)
  • Laterally extensive alteration (a large system)
  • Known mineralization; zinc, copper, silver and lead
  • Secondary mineralization typically associated with larger VMS systems – tin, enrichment of P2O5 “icelandite”
  • Geophysical signatures (EM, IP, magnetics, and gravity)

We believe we are now moving to the final stages of our exploration efforts. We have quantified geochemical, geophysical and geological (structural) targets and are working on prioritizing these for the next stage of exploration. We expect to be drilling in the fall of 2013 after a full compilation of the data.” – Kirk McKinnon, President & CEO

Two drill holes (BP13-CU19 and CU20), were drilled on the Butler 3 geochemical/geophysical anomaly. No appreciable copper or zinc mineralization was intersected within these drill holes, however the lithologies intersected sodium depleted intermediate and felsic volcanic rocks. This geochemical signature represents a classic alteration vector for VMS mineralization, and leads Company geoscientists to the conclusion that VMS mineralization is to the south-west.

The targeting of the south-west likely represents the extension of the mineralized zone intersecting in drill hole BP12-Cu14. It appears that BP12-Cu19 and BP12-Cu20 are lateral to the mineralized zone.

  • Hole BP12-Cu14 intersected 41.5m of 0.4% Cu, 3.26% Zn and 6g/t Ag
    • Including:
    • 12.5m of 8.54% Zn and 6.24 g/t Ag
    • 5.0m of 1.18% Cu, 3.86% Zn and 14.48 g/t Ag

The target area to the south-west is corroborated by a coincident EM and IP anomaly. Before drilling this target however, the Company intends to conduct a robust structural analysis of the existing drill holes under the direction of Rogerio Noal Monteiro, Ph. D. (Vektore Exploration and Consulting). This data will be used in conjunction with the geochemical and geophysical vector analysis to guide drill targeting.

Drill holes BP13-CU21 and CU22 were drilled on the Butler 4 geophysical anomaly (with coincident IP and EM geophysical anomalies). BP13-CU22 intersected 7.50% zinc over a 3 metre interval, and 0.23% copper over 2 metres. Drill hole BP13-CU21 intersected 0.15% copper over a 12 metre interval. These drill intersections are significant in that they pierced the upper edge of a large sub-vertical electromagnetic plate that was postulated to be associated with VMS mineralization. Now that the Company has verified that this geophysical target is associated with copper and zinc mineralization, a detailed analysis of the structural geology will be undertaken on the target. This information, in conjunction with geochemical and geophysical analysis will be used to develop discrete drill targets.

Montoso zone in Mexico drilling intersects pyrite-rich porphyry alteration containing broad intervals enriched in silver

Posted by on Tuesday, 9 July, 2013

Westminster Resources Ltd. has compiled results from five core holes drilled on the Montoso Target of the Company’s Cumbral-San Bartolo project in Sonora, Mexico. This portion of Westminster’s concessions is being explored through an earn-in Option Agreement with Capstone Mining Corp. (“Capstone”) who have 49% interest in the project having funded $3.3 million to date on exploration. A further contiguous 9,615 hectares of new mineral concessions have been added to the project.

A total of 4,163 meters was drilled in the five holes to test a complex geophysical anomaly system coincident with variably anomalous soil geochemistry and extensive leached gossanous zones. The geophysical surveys produced strong IP chargeability/resistivity responses associated with both high and low magnetic anomalies. The holes were designed to test various gradations in IP response intensity. All holes were drilled on angled (not vertical) projections. This drilling was a portion of the second phase of the project’s exploration with Capstone which also included alteration mapping, prospecting, soil geochemical sampling and geological mapping.

All holes encountered abundant pyrite as disseminations, on fractures and in veinlets in intrusive host rocks (granodiorite, feldspar porphyry, igneous breccia and magnetic mafic intrusive) which exhibit weak to moderate porphyry-related alteration (potassic-phyllic) and sparse veining to minor sheeted vein and stockwork development (“B and D veins”) occasionally containing molybdenite. The nature of the metal content, and geologic interpretation of the core suggests that this first phase of drilling at the Montoso Zone has encountered a pyritic peripheral silver-enriched halo component of a laterally extensive porphyry hydrothermal system.

The Montoso Zone drilling showing elevated results. Holes 1, 2 and 5 tested the central and south high chargeability and magnetic high and low patterns while holes 3 and 4 were designed to test the northern edge of the Montoso target and a blanket-like conductivity anomaly extending further to the north. (See Drill Hole Location and Alteration Maps at )

Mineralization is characterized by high-grade, gold-copper-silver veins, breccias associated with porphyry deposit-style systems and hematite-magnetite-sericitized zones and structures containing copper-gold-silver mineralization in an IOCG / Porphyry setting.

Recent airborne VTEM and MAG geophysical survey results for the newly-discovered Cumbral-San Bartolo area identified district-scale alteration and magnetic highs and lows associated with regional structures and intrusive emplacements. Completed ground magnetic highs and lows associated with regional structures and intrusive emplacements. Completed ground magnetic and IP geophysical surveys confirmed airborne anomalous patterns and mapping identified surface mineralization associated with a large hydrothermal system.

Completed aggressive exploration in 2012 included expanded 3D-IP and ground MAG coverage (219 Line kilometers), soil sampling (5,000 samples), mineralization mapping and diamond drilling (7 holes, 1,641 meters). The new 3D-IP chargeability survey identified the 1 X 1-1/2 kilometer high chargeability Montoso target and numerous other copper-silver-gold mineralized zones. 2013 drilling at Montoso is directed at this large porphyry system.

Magnetic and IP surveys for copper-gold porphyry target in BC

Posted by on Thursday, 20 June, 2013

COLORADO RESOURCES LTD. reports the results of ground magnetic geophysical surveys recently completed and also announce the start of a 5,000 m drill program on its 100% owned North ROK Property (Porphyry copper-gold) located 15 kms northwest of Imperial Metals Red Chris Mine in NW British Columbia.

As previously reported in news release dated June 12, 2013 Colorado discovered a new Induced Polarization (I.P) chargeability anomaly that is 1 km north of the discovery drillhole in an area of limited outcrop. Preliminary modeling of the recently completed geophysics indicates that this new I.P chargeability anomaly measures 500-800 m wide and 1400 m long. Ground magnetic surveys conducted over the same area revealed two anomalies flanking the I.P chargeability anomaly and one anomaly in the core of the I.P anomaly. The magnetic anomalies flanking the I.P anomaly measure approximately 300 m by 750 and 200 m by 700 m; the magnetic anomaly in the core of the I.P chargeability anomaly measures approximately 500 m by 700 m. See map attached (to view, visit the following link: Company’s website for details.

The Company is encouraged that these new coincident I.P and magnetic anomalies appear to have a similar geophysical signature to areas of known mineralization on the Property.

The Company is also pleased to announce that a 5000 m diamond drill program has commenced on the property within the existing permits.

Adam Travis, the Company’s President and CEO stated “I’m very pleased with the progress our technical team has made on our North ROK property to not only fine tune our next phase of drilling but to also advance other exploration targets on our claims. I look forward to a very exciting next round of drilling.”

Airborne and ground geophysics on Swayze Gold Property

Posted by on Thursday, 14 March, 2013

GoldON Resources begins 2013 Exploration on Swayze Gold Property in Ontario’s Abitibi Greenstone Belt – Video Summary on

Based on interpretation of airborne geophysical data, GoldON Resources’ independent geological consultant has identified a priority area for the next phase of exploration on the company’s 100% owned Swayze Gold Property.

The 6,640 hectare Swayze Project, comprised of three non-contiguous claim blocks, is located half way between Timmins and Sudbury, Ontario in the Swayze greenstone belt, which is the southwestern extension of the Abitibi greenstone belt. These properties either adjoin or are surrounded by Iamgold’s multi-million ounce Cote Gold Project. Iamgold is GoldON’s largest shareholder, holding two million or approximately 10% of the outstanding shares.

The geological interpretation focused on the 6,000 hectare Neville Potier claim block, and while there were several areas that show good promise in terms of geology and structure, one area reportedly stood out above the rest as shown on the Aeromag map. Of particular significance is a major magnetic low that includes the historical Chester gold operations and the Côté Gold deposit and extends north into GoldON’s Neville Potier claims. This geophysical feature could be indicative of a major alteration system

Previous drilling on the Chester property encountered anomalous gold and similar alteration and fracturing as found at the Côté Gold deposit less than 1 kilometre to the south.

Access to the priority area of the Neville Potier claims is excellent year round with a paved road through the middle of the claims.

The company is arranging an equity financing to further fund the next phase of exploration on this property and Iamgold has expressed an interest in participating.

Line cutting and an IP /resistivity geophysical survey will commence shortly. The results of this survey will be used to identify the highest priority drill targets.

New Airborne and Ground Geophysical Surveys on Detour Gold Trend Properties

Posted by on Friday, 1 March, 2013

Adventure Gold Inc. announces the commencement of a significant exploration program on its 100%-owned Detour Quebec project along the Detour Gold Trend (“DGT”) in Abitibi, Quebec. The exploration program will consist of airborne and ground geophysical surveys on the best targets identified last year following a comprehensive geological modeling of the DGT. A helicopter-borne electromagnetic VTEM-type survey (VTEM) totalling 575 km, 400 km of detailed ground magnetic surveys and 30 km of Induced Polarization (IP) surveys are currently underway or will start soon.

Since last year, the Company has been actively exploring its Detour Quebec properties by completing 103 kilometres of IP surveys, 365 kilometres of detailed ground magnetic surveys, and 912 kilometres of high-definition helicopter-borne magnetic surveys. This work has highlighted new and very promising drilling targets by identifying IP anomalies close to strong gold anomalies in till, along strike from positive gold results intersected by historical drill holes. Geological modeling outlined nine possible distinct bedrock source areas along the Sunday Lake, Massicotte, and Lower Detour/Grasset gold deformation zones on our properties. Three possible bedrock source areas were covered by geophysical surveys (IP and Mag) in 2012 and nine new ground geophysical surveys will be completed over the other areas this year (see Figure 1 and press release dated November 14, 2012).

On the two northernmost claim blocks (Manthet and Martigny) respectively located 15 and 25 kilometres from the Detour Lake mine, adjacent and close to the Ontario border, two VTEM surveys totalling 575 km will be completed. Historically, very little exploration work has been completed on these claims and limited drilling in one area outlined VMS-style gold, zinc and copper mineralization. This geological environment shows some similarities with the Martiniere project located further east, where Balmoral Resources Ltd is actively exploring the Martiniere West, Bug Lake, and Martiniere East zones. In this emerging gold play, very high-grade drill intersections were recently reported, namely 273.0 g/t Au over 3.9 metres and 11.7 g/t Au over 8.9 metres (see Balmoral Resources Ltd press releases dated August 16, 2012 and January 28, 2013). The VTEM-type survey is known for its exceptional depth penetration and provides a more accurate definition of electromagnetic anomalies than conventional systems. At the Detour Lake mine, the original discovery of the main zone is directly credited to the presence of an airborne electromagnetic anomaly detected during an Input-type survey in 1974. On the Manthet and Martigny claim blocks, new east-west and northwest trends outlined last year and interpreted as subsidiary faults of the Sunday Lake deformation zone will be covered by the VTEM survey.

“Following recent successes in identifying quality drilling targets, firstly by outlining the best areas using our comprehensive geological model and secondly by performing detailed geophysical surveys, we have great expectations for the 2013 geophysical surveys, which will be mainly conducted over new claims acquired in April 2012. Once this work has been completed, we will plan a substantial drilling program scheduled to start next winter”, stated Marco Gagnon, President and CEO of Adventure Gold Inc.

The Detour Quebec project includes nine properties, 100%-owned by the Company, totalling 747 claims and covering a surface area of 40,397 hectares or 404 km2. The Detour Quebec properties are strategically located along the DGT over 80 km strike length and encompass three major proven gold structures, namely the Sunday Lake, Massicotte, and Lower Detour/Grasset deformation zones. The DGT hosts the Detour Lake gold deposit with NI 43-101 proven and probable reserves of 15.6 M ounces of gold (from global measured and indicated resources of 23.3 M ounces and inferred resources of 5.8 M ounces: see Detour Gold Corporation press release dated January 25, 2012). Adventure Gold’s Detour Quebec properties are adjacent to Detour Gold Corporation properties located on the Ontario border.

Jules Riopel, P.Geo., Vice-President Exploration and Acquisitions, acting as the Company’s “Qualified Person” as defined by NI 43-101, has reviewed this press release and supervised the exploration program on the Detour Quebec properties.

Induced Polarization Survey on Abitibi Greenstone Belt, Northwestern Quebec

Posted by on Thursday, 10 January, 2013

Belmont Resources Inc. updates the progress on the Berthiaume (the “Be”) property.

Geosig Inc. of Quebec completed approx. 46.2 km. of induced polarization (TDIP) geophysical survey with a dipole-dipole electrode configuration on the three areas line cut, and as recommended in the NI 43-101 Report to establish the potential of the structural features of the property. A provision for drilling has been budgeted to test the IP anomalies from the IP survey interpretation, which is expected in a couple of weeks.

The Be Property is located halfway between the towns of Matagami and Lebel-sur-Quevillon, located in the prolific Abitibi greenstone belt of northwestern Quebec. It consists of two designated claim blocks of eight claims covering 447.84 ha (West Block) and 23 claims covering 1,287.56 ha (East Block).

Regional and local geology

The Berthiaume property is located in the Harricana-Turgeon Belt, an Archean volcano-sedimentary and plutonic rocks assemblage that constitutes the northern part of the Abitibi sub-province, Superior Province (Hocq, M. DV 89-04). Volcanic and sedimentary rocks of the Berthiaume area (Joly, M., MB 93-13) occur as a homoclinal sequence striking east-west, dipping steeply to the north with a polarity also to the north. From bottom to the top (from south to north), the belt starts by massive to pillowed mafic volcanites known as the southern volcanites. These are surmounted by a thick sequence of clastic sediments and iron formations that belong to the Taïbi Group. Farther north lies a thick bimodal sequence of felsic lavas and pillowed, vesicular and porphyric mafic lavas. These are referred as the northern volcanites. The north and south borders of the Harricana-Turgeon Belt are composed of large felsic, mafic and ultramafic intrusive bodies. One of these is the Bell River anorthositic complex, which covers the northern part of Berthiaume Township. The metamorphic equivalents of the lavas and sediments are observed along the borders of the
intrusions as amphibolites (metavolcanites) and biotite-quartz schists (metasediments). NNE striking diabase dykes of kilometric extension constitute the younger geological unit as they cut all the other formations.
A penetrative E-W and sub-vertical schistosity is observed everywhere. The most extensive structures are E-W shear zones, followed by NE to NS striking faults.
The only mineralization reported on this property consists of massive pyrite and pyrrhotite horizons containing sphalerite and chalcopyrite locally in quantities ranging from trace to a few percent. In Umex drill holes, in the northeast part of the East Block, such mineralization was hosted by various graphitic rocks including argillites, breccias and conglomerates. As mentioned previously, highly-oxidized outcrops containing up to 70% pyrite and pyrrhotite with low values in Cu and Zn were also found in the same area during geological mapping by Falconbridge.


Joutel Property – Exploration Planning

The Company will also be considering recommended line cutting and IP work next on its Joutel Township optioned property. Significant activity has been announced recently by other exploration companies in the Joutel area such as: Bold Ventures Inc. (“BOL”)-December 7/12 nr; Visible Gold Mines (“VGD”)-December 4/12 phase 2 drilling nr; and Globex Mining (“GMX”)-November 5/12 nr announcing recent acquisition of 100% interest in the former Joutel copper mine (copper, zinc, silver) where Globex already has landholdings that include the 100% owned Eagle gold (gold, silver) and Poirier mines (copper, zinc, silver, gold), and a large package of prospective claims with excellent exploration potential.
