 Patriot Gold Corp.  a developing gold and silver exploration and production company, announces the results of an airborne magnetic survey of its Moss Gold-Silver project located in the historic and active Oatman Mining District near Bullhead City, Arizona. Results of the survey included use of magnetic, field mapping and historic mineral and workings data.

  • The main Moss resource and hosting structure lies along a well-defined magnetic high and includes three kilometers of unexplored potential on one structure.
  • Nine magnetic linear anomalies associated with know mineral occurrences and historic workings were found as part of the Moss structure, indicating potential for hosting new discoveries along these structures.
  • One structure includes nearly six kilometers of a mapped extension of the Gold Road deposit which previously produced nearly 500,000 ounces at 0.32 opt gold.
  • The implications of the new data indicate that the exploration potential of the Moss site is very good and that there is the likelihood of further discoveries on the Moss property.
  • Following the interpreted results of the survey, the Company’s partner Northern Vertex Mining Corp., is currently designing an exploration program to assess the potential of the additional structures identified that would run concurrently with Phase II – Operations Phase of the Moss project plan.

The survey found a total of 21 kilometers of potential strike length along the entire Moss Mine property. In addition, several other linear magnetic lows and highs were found that would require ground work to determine if they are mineralized.

In June 2013, a preliminary economic assessment of the Moss Mine Project, which did not include the current survey results, assessed the measured and indicated gold equivalency of the site at 654,000 ounces with an inferred resource estimate of 82,000 ounces.

“While the results of the survey are preliminary at this stage, this type of mapping has been the foundation for many successful early stage exploration programs,” said Bob Coale, CEO of Patriot Gold. “Considering that the historic production in the Oatman District previously exceeded 2 million ounces of gold production, we believe the survey results highlight the Moss Gold-Silver project’s high potential for additional gold discoveries which could further increase the value of this property.”

Geology of the Moss Mine Property

The project area is underlain by Tertiary quartz monzonite (a coarsely crystalline rock composed primarily of quartz, plagioclase and orthoclase) intruding Tertiary age volcanics. Precambrian basement rocks underlie the volcanics. The veins consist of quartz-calcite and lesser adularia. The Moss vein system is up to 45 feet thick and can be traced on surface for over a mile. The hanging wall of the main vein commonly has several tens of feet of stockwork veining. Dipping 40-60 degrees to the south from a high ridge, the quartz-calcite veins and stockworks are being drilled as a bulk minable gold target. Based on the results to date, Patriot believes the Moss Mine project has the potential for an economic resource of leachable gold and silver in the order of one million ounces of gold equivalent.


Integrated airborne geophysics and geologic data interpretation for new Eskay-Creek style deposits

Posted by on Wednesday, 9 April, 2014

Dolly Varden Silver Corporation announces that through recent geoscience modeling and ongoing interpretation, the Company has focused its primary advanced exploration target areas on three corridors within the Dolly Varden property. Work is now being done to prioritize the most prospective drill-ready targets within these corridors. The corridors and targets were chosen for their potential to best expand areas of known high-grade silver mineralization and to identify new Eskay-Creek style precious metals deposits.

 

 The three targeted corridors are the 1) Torbrit-Red Point Corridor – following known silver mineralization underneath Red Point, an Eskay-Creek style target; 2) Musketeer Corridor – which runs along the east side of the Kitsault river with numerous Ag-rich epithermal vein-type showings with strong potassic radiometric signatures; and 3) Wolf-Surprise Corridor where an Eskay-Creek style host formation containing silver-rich VMS mineralization was identified by the Company’s 2011 drill program.

————————————————————————————————————————————
Through recent modeling and ongoing interpretation, the Company has now moved from kilometer scale targeting to meter scale targeting within these defined corridors. The Company’s technical team is working to delineate specific drill ready targets within these corridors. An aggressive 40 to 50 hole (13,500 meter drill program) is being finalized, subject to financing.
The combination of airborne MAG, VTEM, ZTEM radiometric, and geochemical data, along with geological and structural mapping, was used to define priority target zones. These helped define steep linear features, syngenetic faults, lithologic contacts related to basin formation, and key fluid controlling structures. In addition, key rock units, contact zones and alteration zones most likely to be associated with mineralization, were identified.
This compilation has demonstrated that the known deposits, showings, and related alteration zones are all located within a rift setting. The key rock units that infill the rift have also been identified, and these represent viable targets for Eskay Creek style VMS mineralization. Drilling will be conducted within corridors where mineralized occurrences and coincident alteration haloes point to extensive hydrothermal fluid flow. The key target areas for 2014 drilling include syngenetic VMS-style mineralization and associated feeder structures.

New Strongly Conductive Target on Feagan Lake Graphite Project

Posted by on Wednesday, 26 March, 2014

Metals Creek Resources Corp.  reports that the company has discovered several conductive electromagnetic targets on its recently staked, 100% owned Feagan Lake Graphite property which is located approximately 7 km due west of  Zenyatta’s hydrothermal graphite discovery.

These new electromagnetic (EM) conductive responses were flown with the VTEM plus time domain system targeting previously identified magnetic lows that resulted in the discovery of several new exploration targets exhibiting similar features to that of Zenyatta’s hydrothermal graphite discovery. One of the EM responses in particular returned a strong conductive response on all channels with an associated magnetic low.

The Feagan Lake claim block consists of 12 claim blocks totaling 175 claim units and is located immediately west and adjacent to Zenyatta’s claim block.  The Feagan Lake property to the best of management’s knowledge has never been flown for EM conductors making this a brand new discovery demonstrating the potential for the area to potentially host additional graphite mineralization.

Metals Creek’s President and CEO, Alexander Stares states, “With the discovery of several new EM anomalies within favorable stratigraphy to host possible additional graphite mineralization, it provides Metals Creek with an exciting new project strategically located adjacent to Zenyatta’s hydrothermal graphite discovery.  This new highly conductive EM target will be the focus of additional exploration work going forward.”

 


Geophysics indicates conductive core at Mary March in Central Newfoundland

Posted by on Wednesday, 26 March, 2014

Canstar Resources  provides an update on the current exploration activity for its Mary March Project, located near Buchan’s Junction in Central Newfoundland.
The Company’s recent borehole geophysical program conducted on holes drilled during 2013 has provided results that distinguish a high priority drill target near the Mary March massive sulphide zone. All of the holes surveyed clearly point to a more conductive zone downdip and to the east of holes MM13-29 and MM13-30, suggesting the mineralization is open for expansion in these directions.

 

 

 

 

 

 

 

 

 

————————————————————————————————————

The Mary March zone is the initial discovery area drilled by Phelps Dodge in 1999 where they encountered impressive grades of 10.1% Zn, 1.68% Pb, 0.64% Cu, 122.1 grams per tonne (g/t) Ag, and 4.2 g/t Au over 9.63 meters. The drilling completed by the Company in the Mary March area successfully added to these results, encountering massive sulphide zones with two separate holes. In drillhole MM13-30, 11.6 meters of mineralization containing 3.6% Zn, 0.1% Cu, 0.8% Pb, 25 g/t Ag, and 1.5 g/t Au; including a 3.6-meter high-grade zone containing 7.5% Zn, 0.04% Cu, 1.37% Pb, 26.1 g/t Ag, and 1.7 g/t Au, and extended the Mary March Zone to depth. In MM13-29, 5.0 meters of mineralization was encountered, containing 4.82% Zn, 0.38% Cu, 1.04% Pb, 71.3 g/t Ag, and 1.8 g/t Au, including 3.5 meters of 6.21% Zn, 0.13% Cu, 1.42% Pb, 82.8 g/t Ag, and 1.9 g/t Au (see Company Press Release dated January 21, 2014).
Results for surveys completed for holes in the Nancy April area, which is located approximately 500 meters southwest of the Mary March zone require more data and investigation, remaining relatively underexplored compared to the Mary March zone.

“This is exciting news for our shareholders and for the Mary March project,” stated Danniel Oosterman, President and CEO of Canstar. “In an area where mineralization is known to give weak responses, we are encouraged to find such an obvious anomaly offhole to known mineralization. Needless to say the company regards this as a high priority target for its next drilling program.”


Strong EM Targets Have Been Detected Downhole Geophysics at Yepleu and Samapleu Deposit

Posted by on Monday, 24 March, 2014

Sama Completes Downhole Geophysics on Five Drill Holes at Yepleu and Samapleu Deposit (West Africa); Strong EM Targets Have Been Generated

Sama Resources Inc./Ressources Sama Inc. announces the completion of the Downhole Electromagnetic Geophysical (“DHEM”) survey on five (5) holes at the Samapleu and newly discovered Yepleu nickel-copper-palladium Deposits in Côte d’Ivoire, West Africa.

Abitibi Geophysics Inc. from Val d’Or in Canada performed the survey and the interpretation is performed by Mr. Daniel Card, Senior Geophysicist for Southern Geoscience Consultants, Australia.

Three holes were surveyed at the Yepleu deposit, one hole at the Samapleu Main and one hole at the Samapleu Extension 1 deposits.

Preliminary inspection of the data indicate strong Electromagnetic (“EM”) responses on all holes surveyed. Detailed interpretation and modelling is in progress for the following geophysical anomalies:

 
Hole         Location       Response: Depth from surface in meters ("m") 
SM34-570407  Extension 1    - EM anomaly at around 280-320 m 
SM44-525290  Samapleu Main  - EM anomaly at around 150 m 
YE31-637117  Yepleu         - EM anomaly at around 120 m 
YE31-694543  Yepleu         - EM anomaly at around 160 m 
YE23-398223  Yepleu         - EM anomaly at around 40 m

“The survey was performed extremely well by Abitibi Geophysics,” stated Dr. Marc-Antoine Audet, President and CEO. “We look forward to some very good drilling targets from the modelling.” “We are working on this as top priority,” added Mr. Card, Senior Geophysicist for Southern Geoscience Consultants.

The Yepleu discovery is located 18 kilometers (“km”) southwest of the Samapleu nickel-copper-palladium deposits. Regional geological mapping has identified that the geological host of the newly discovered Yepleu nickel-copper-palladium mineralization extends beyond the original 3 km by 600 to 800m to an area as vast as 6 km x 4 km (Refer to News Release dated February 03, 2014).

A total of 18 diamond drilling holes for 3,320m were drilled at the Yepleu discovery testing the large sub-horizontal mineralized layer associated with pyroxenite, gabbro-norite and diorite units been part of the newly identified and described Yacouba Layered Complex (Gouedji et al., submitted to Bulletin de la Société Géologique de France (BSGF), January 24, 2014). Exploration results for all drilled holes at Yepleu will be announced in a subsequent press release.

Exploration Model and Targets

Exploration to date has focused mostly on shallow targets (<150m) at the Samapleu and Yepleu deposits. Sama believes that mineralization at the Samapleu deposits could plunge deeper and could extend laterally as suggested by responses obtained from the Helicopter Electromagnetic survey completed in January 2013 and by the current DHEM survey.

At Yepleu, the Company is chasing embayments or structural features that would have trapped mineralised pyroxenite within the sub-horizontal layered complex assemblage.

The technical information in this release has been reviewed and approved by Dr. Marc-Antoine Audet, P.Geo and President and CEO of Sama, and a ‘qualified person’, as defined by National Instrument 43-101, Standards of Disclosure for Mineral Projects.

For more details, the reader is invited to review Sama’s updated compilation on its website at: http://www.samaresources.com/i/pdf/Sama_Corporate_Presentation.pdf

 

amapleu Project

“Samapleu poly-metallic deposits will give Sama the opportunity to become the first poly-metallic producer in West Africa.”

The Samapleu deposit is comprised of disseminated and semi-massive to massive sulphide mineralization hosted by a mafic-ultramafic intrusion located in the southern border of an early Proterozoic age deformation zone affecting the Archean Charnockitic shield. Mineralization is strata bound within pyroxenite layers of the Samapleu mafic-ultramafic complex.

The disseminated mineralization is typically characterized by fine isolated grains to large granular aggregates of iron, nickel and copper sulphides. Sulphide phases observed so far include pyrrhotite, chalcopyrite, pentlandite and minor pyrite. Pentlandite occurs as inclusions in pyrrhotite. Disseminated sulphide occurs as fine grains of 0.5 to 1 mm in diameter, showing a high ratio of pyrrhotite versus chalcopyrite. Sulphide veinlets and fine filaments are also present. Composite grains of sulphide material are dominant, forming sulphide masses of odd shapes ranging from a few millimeters up to several centimeters in any one dimension.


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.

Location:

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

Property:

  • 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.

Highlights:

  • 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.

Recent investigations of geophysics abilities in aquifer mapping and resource evaluation

Posted by on Thursday, 13 March, 2014

Buried beneath the glaciated terrain, valleys filled with coarse-grained permeable sediments  potentially are great sources of fresh ground water. During the last several years Geological Survey of Canada has been investigating geophysical methods potential, particularly airborne electromagntics, for mapping and resource evaluation of buried valleys.   Spiritwood valley aquifer in southern Manitoba has been chosen for the investigations. Heliborne AeroTEM, VTEM, fixed-wing TEMPEST and MULTIPULSE, ground electrical resistivity and time-domain methods, seismic reflection and borehole data have been involved into the complex analysis. Recently collected ground TEM data for Spiritwood and the report (G.A. Oldenborger and K. Brewer, 2014) has been released: http://geoscan.nrcan.gc.ca/starweb/geoscan/servlet.starweb?path=geoscan/fulle.web&search1=R=293700.

Recent Airborne EM Survey close to Albany project

Posted by on Wednesday, 12 March, 2014

Xmet Inc. has successfully completed a Versatile Time Domain Electromagnetic Surveying (“VTEM”) survey, comprising 437 line kilometres, over 20,000 acres of recently staked 100% owned Xmet claims on its Blackflake project.
Three electromagnetic (“EM”) bedrock targets were delineated during the latest survey, including a more detailed survey over the Prime Target discovered and announced in Xmet’s December 12th, 2013 news release. Geotech, who flew the survey and assisted in interpreting the results, have concluded that all three of the anomalies extend into the bedrock beneath overburden and limestone cover.
“A tightly spaced VTEM grid survey was flown over our Prime Target in order to obtain higher resolution over the original TDEM anomaly which was originally defined over a length of 1500 meters,” said Alexander Stewart, Chairman and CEO of Xmet Inc. He continued by saying, “VTEM technology provided much deeper penetration than the TDEM survey flown over the Prime Target in late 2013. With this latest round, the conductivity and the size of the Prime Target is confirmed. The Prime Target is defined by an electromagnetic anomaly in bedrock with an associated magnetic low. The target is geologically constrained between two major diabase dykes. Two new bedrock conductors were also discovered which have similar geophysical characteristics. We are very excited about the potential of these targets, and with our ground permits now in place we are getting closer to drilling these targets.
Xmet’s Blackflake Project comprises over 29,000 acres of 100% owned claims approximately 60km to the northwest of Hearst, Ontario and is adjacent to Zenyatta’s Hydrothermal Graphite Deposit. Xmet has now conducted three airborne electromagnetic surveys, VTEM and TDEM, which discovered multiple electromagnetic conductors making the targets highly prospective for further exploration. Xmet has developed an excellent working relationship with the Constance Lake First Nation, with whom the company signed an ongoing Exploration Agreement.

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 (http://www.aurasilver.com/s/Home.asp) 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.


The renewed Interest in Pecors Magnetic Anomaly-Serpent River Property Near Elliot Lake, Ontario

Posted by on Friday, 21 February, 2014

International Montoro Resources Inc. – The Serpent River Property, Elliot Lake, Ontario claims consist of 10 mining claims (115 units) covering approximately 1,840 hectares located in Gaiashk & Joubin Townships. Recent renewed interest has been shown in the 3 upper northwest claims known as the Pecors Anomaly. Click following for maps/regional geophysical overview http://ow.ly/tNTbz.

Montoro congratulates Kelly Strong, V.P. of Ontario and UK Operations -Vale, in the recent startup of the Totten Mine (Totten lies 40 km to the west of Sudbury and approx. 50 km from Pecors). This is Vale’s sixth operating mine in the Sudbury Basin. A polymetallic orebody with good nickel and copper grades as well as precious metals. Click following for the complete story: http://ow.ly/tLq2T. (See page 1 & 19-34 re the Totten Mine and page 15 re the KGHM Victoria Mine Projects)

The Uranium and Rare Earths discovered in the southwest portion at Serpent River may prove to be a sideshow to another deposit type. In a 2009 summary of the Ontario Geological Survey field work, a strong geophysical anomaly on the claims that was previously thought to be caused by an iron formation was reexamined. The new interpretation on the Pecors anomaly concludes it may be the result of contact style nickel-copper-PGE mineralization similar to that found to the east at Sudbury. Sediment sampling from Pecors Lake has shown high levels of nickel and chromium, lending further weight to this analysis. The total field magnetic anomaly strikes northwesterly and is about 15 km long and about 4 km wide.

Gravity survey for uranium in Athabasca

Posted by on Thursday, 20 February, 2014

Athabasca Nuclear Corporation  announces the completion of gravity surveys which have resulted in the identification of twenty-three (23) gravity low anomalies on the Western Athabasca Syndicate’s (the “Syndicate”) flagship Preston Lake Uranium Property (the “Property”). The identification process covers a portion of its’ Property and included a RadonEx survey (ground and water) to further refine targets in advance of a drill program scheduled to commence in March.

“As the largest tenure holder in the Western Athabasca Basin and having carried out the most significant regional target delineation program in the area, we are keen to commence further exploration through drilling on some of the gravity low anomalies identified to-date,” stated Ryan Kalt, Chief Executive Officer (Interim) of the Corporation.

Preston Lake Property Map and Regional Exploration Corridors:

http://www.athabascanuclear.com/wp-content/uploads/2014/02/Patterson_Lake_Regional_Map.pdf

Interpretation of the gravity data by Phil Robertshaw, P.Geo., has successfully delineated gravity low anomalies associated with previously identified high-potential exploration corridors defined by structure, magnetic lows, conductors, favorable geology and geochemistry. Gravity is a defining tool for exploration for uranium in the Athabasca Basin and was a key mechanism for vectoring in on the recent discovery made by NexGen at the Rook 1 Project.

 

Hydrothermal fluids associated with high grade uranium deposits will cause extensive alteration of the host rock, resulting in displacement and removal of minerals/elements, creating porosity and subsequent density contrast. This density contrast will be expressed as a gravity low anomaly and is a prime drill target when qualified by other coincident indicators of uranium mineralization such as geochemistry and radon.

Preston Lake Property - Gravity Survey Coverage:

http://www.athabascanuclear.com/wp-content/uploads/2014/02/Preston_Lake_Exploration_Update.jpg

In addition, several of the Syndicate’s gravity low targets have been further refined using a proprietary RadonEx survey which has been instrumental in assisting with numerous discoveries in the Athabasca Basin region. The Syndicate is carrying out a ground EM survey to further refine conductor trends and pinpoint drill pad locations. Details concerning the upcoming drill program shall be provided in the near-future.

The 246,643 hectare Preston Property is the largest individual property proximal to Fission Uranium Corp.’s Patterson Lake South (“PLS”) high-grade uranium discovery and the recent discovery made by NexGen Energy (“NexGen”) on the Rook 1 Project . The Syndicate is the largest land tenure holder in the southwest Athabasca Basin region including properties strategically situated to the southwest and to the northeast of the PLS and NexGen discoveries.

About the Preston Lake Property:

The 246,643 hectare Preston Lake Property is the largest land package proximal to the Patterson Lake South (PLS) high-grade uranium discovery, owned by Fission Uranium Corp. The Syndicate continues to employ a systematic, proven exploration methodology that has led to numerous uranium discoveries in the region and throughout the Athabasca Basin. This has been very effective in identifying numerous high-quality targets with similar geological features and exploratory indicators also present at the nearby PLS discovery and in other deposits in the Athabasca Basin. Management cautions, mineralization present on proximal properties is not necessarily indicative of mineralization on the Syndicate’s Property.


Geophysical exploration program in Nicaragua

Posted by on Tuesday, 18 February, 2014

Caza Gold Corp. announces that the Company has initiated the 2014 exploration program at the Los Andes and Pochote properties in Nicaragua. The Company is planning a large airborne geophysical survey and a drilling program which will test 2 of the highest priority gold targets.

Plans are underway to complete a geophysical survey along a 12 kilometer long trend of continuous alteration within the Los Andes and Pochote claims, followed by a drilling program to test two gold targets not previously drill tested during the 2012 Pedregal program. The upcoming drilling will test the Quisaltepe and San Francisco gold zones. Access agreements have been obtained for the San Francisco area and drill access road construction is underway. Negotiations for access in the Quisaltepe area are being finalized. The drilling program is expected to begin, pending contractor scheduling, by April and is planned to complete approximately 10 to 15 holes each 200 to 250 meters deep. A dedicated budget of approximately CDN$1.3 million has been set aside from the proceeds of the December 2013 CDN$2.5 million financing to execute the exploration program.

The Company has contracted Aeroquest Airborne to complete the helicopter based geophysical survey which will cover approximately 36 square kilometers over the Pedregal, Quisaltepe and San Francisco gold targets acquiring versatile time domain electromagnetic (VTEM) and magnetic data along approximately 530 line kilometers at 100 meter line spacing. The survey is scheduled to begin in March pending the importation of the survey equipment and final scheduling of personnel and equipment. Geophysical survey results in conjunction with geochemical results, structural and alteration mapping will further define the drilling locations.

The VTEM and magnetic data are targeting the conductive massive sulfide horizons and the resistive silicified zones associated with large faults and possible areas of gold mineralization. The magnetic portion of the survey will provide additional information identifying the fault zones and deeper porphyry style mineralization and intrusive bodies. The survey will cover the Pedregal area, drilled in 2012, which intersected thick horizons of sulfide mineralization and strongly silicified zones with elevated but sub- economic gold concentrations (refer to Nov. 29, 2012 news release for details) and along the 10 kilometer trend to the San Francisco target at the south end of the zone.

Los Andes High Sulfidation Gold Property, Nicaragua

The Los Andes Property is located approximately 1 hour east of Managua on Highway 7 with excellent access. The property covers approximately 6,575 hectares and is strategically located within the Central Nicaragua Gold Belt between the El Limon and La Libertad Mines of B2 Gold.

The Los Andes property is a high-sulfidation style of gold mineralization.  High-sulfidation gold systems host some of the largest gold deposits in the world with examples such as Yanacocha and Pierina in Peru.  Favorable alteration and mineralization has been traced along the regional northeast trending Los Andes structure for at least 11 km on the Los Andes property.  The extensive alteration system is exposed on the surface and consists of very strong silicification associated with zoned alteration from higher temperature advanced argillic zones surrounded by successively lower temperature argillic, and propyllitic alteration.  The alteration is associated with anomalous values of gold, silver, and highly anomalous levels of indicator metals such as bismuth, tellurium, selenium, arsenic, antimony, and mercury.


Airborne EM before the discovery of wide spread gold-silver-zinc-copper mineralization

Posted by on Tuesday, 18 February, 2014

Bayfield Ventures Corp. announces the completion of a National Instrument (NI) 43-101 Technical Report on the Company’s 100% owned mineral rights “B” Block gold-silver property, Rainy River district, north-western Ontario.

 

 

 

 

 

 

 

 

 

Drilling on the “B” Block property has resulted in the discovery of wide spread gold-silver-zinc-copper mineralization. No mineral resource calculations have been done on the property. Drilling to date has been relatively wide spaced and shallow. All known mineralized intercepts lie within 400 metres of surface. Less than 5% of the drilling on the property has been done below the 400 metre below surface level.

The property is positioned in the eastern portion of the developing Rainy River district. The south edge of the property is located approximately 350 metres north of the near surface position of the Intrepid shoot, located on ground controlled by New Gold. The Intrepid shoot is a SW plunging, robust zone of gold-silver mineralization that has been jointly delineated by Bayfield Ventures and Rainy River Resources since its discovery by Bayfield in December 2011.

Mineralization on the “B” Block is contained within a package of NNE striking, vertically dipping, strongly foliated, sheared and locally folded dacite porphyry wall rocks. Pervasive sericite-silica +/- biotite alteration is developed within the dacite package. Sericite is dominant in the southern half of the property while biotite and silica are well developed in the northern portion.

The interlayered dacite porphyry, argillite and mafic volcanic lithology of the known rock package at the “B” Block are very similar to that found by Bayfield at its nearby Burns Block property. Additionally, discovered gold-silver-base metal mineralization at the “B” Block is hosted within highly foliated dacite intrusive and or volcanic rocks, again, a setting very similar to that at the Burns Block and at other well mineralized zones along the developing district-scale trend.

The drilling of a series of NW trending angle holes across the SW flank of the strong VTEM anomaly in the northern portion of the “B” Block property is also recommended. Drilling in the heart of the anomaly completed in 2013 showed a rock sequence nearly identical that which overlies the Intrepid Shoot in the eastern portion of Bayfield’s Burns Block project.

The survey was flown in two distinct blocks, an eastern block covering the Burns and “B” Block exploration areas and a western block covering the large “C” Block exploration area. Interpretation of the preliminary data is complete and the following drill targets have been identified:

• A strong, discrete conductor in the east-central portion of the Burns Block has been identified and will be drill tested. No previous drilling has been done in this portion of the property. The anomaly is located in the same area as the multi gram surface samples reported above.

• A strong, discrete conductor in the northeast portion of the “B” Block has been identified and will be drill tested. No previous drilling has been done in this portion of the “B” Block property.

• The cesium magnetic data from the “C” Block survey show clear evidence of mafic volcanic rocks in the northern portion of the property. These rocks are separated from interpreted intermediate volcanic rocks by a sharp contact that is very likely a fault. The interpreted fault contact and the area of interpreted intermediate volcanic (dacite or equivalent) rocks present top quality drill targets at the “C” Block. Drill testing of this area is planned for the first quarter.


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.
