MS Ventures Inc. updates shareholders on the progress of its winter drill programs.

The Company has completed drill testing its 100%-owned base metal massive sulphide-type targets in the Snow Lake greenstone belt of Manitoba and several targets in the North Range of the Sudbury Basin, Ontario. All targets in Manitoba have been selected for drill testing subsequent to the integration of airborne VTEM or ground EM-magnetic geophysical surveys and Mobile Metal Ions (“MMI”) soil geochemistry coupled with a review of historic exploration databases. The Company completed 13 holes with two holes abandoned due to low water supply for a total of 3,259.9 metres. In Sudbury, the Company completed three skid mounted drill holes following up TDEM, VLF-EM and MMI anomalies on the Terra Incognita project for a total of 440.6 metres.

Drill testing of Manitoba targets began on the Reed East project and finished on our Copper project. All targets were confirmed as uneconomic iron sulphide mineralization, generally associated with graphitic argillite within basaltic host rocks.

Neil Richardson, COO states: “The cold winter and spring have been exceptionally good for skid mounted drilling with frozen ground providing good access to many of our planned targets. The cold weather created some problems with small ponds frozen solid, providing an inadequate water source for drilling of two targets. We continue to see excellent correspondence between our geophysical targets and the drill results in explaining the anomalies.”

The drilling for this season was completed on April 17, 2013. The final assay results for the last few holes are outstanding at the time of writing.

CAMAC Energy Inc.  has announced that Sander Geophysics Limited (“SGL”) has completed shooting  airborne gravity and magnetic geophysical surveys on the Company’s Kenya onshore Lamu Basin Blocks L1B and L16 (“Blocks”). The data acquisition covers essentially the entire 12,129 square kilometers in Block L1B and the entire 3,613 square kilometers in Block L16 and satisfies the gravity and magnetic survey requirements for each Block under the relevant Production Sharing Agreements.

The Company expects to receive initial results of the shoot in the third quarter of 2013. Results will be used to optimize the placement of 2-D seismic lines by identifying faults, basement structures and intra-sedimentary volcanic layers and/or intrusions.

“I am pleased that we completed the acquisition of the airborne gravity and magnetic geophysical surveys in Kenya safely, on time, and under budget,” said Senior Vice President of Exploration and Production Segun Omidele. “Our geophysical team will now work with SGL to interpret the data and delineate optimal areas for 2-D seismic acquisition.”

Cassini Resources (ASX: CZI) has defined a large scale high priority nickel-copper sulphide exploration target in a recent versatile time domain electromagnetic (VTEM) geophysical survey over its West Musgrave Project in Western Australia. Source..

The company believes the West Musgrave Project has the potential to host another large nickel-copper sulphide deposit such as BHP Billiton’s nearby 1.66 million tonne copper equivalent Nebo‐Babel deposit.

The target at West Musgrave is defined by a strong electromagnetic anomaly occurring over a strike length of about 600 metres.

The electromagnetic anomaly coincides with a dipolar total magnetic intensity anomaly.

Magmatic nickel sulphide deposits are usually highly conductive, and are often hosted by mafic and ultramafic rocks containing the magnetic iron oxide mineral, magnetite.

Cassini has begun planning and permitting for an on‐ground electromagnetic survey which will assist in defining higher order conductors and help to prioritise subsequent drill program targets.

The Musgrave is a poorly explored province currently experiencing aggressive exploration expenditure following the discovery of BHPB’s Nebo and Babel nickel-copper-PGE sulphide deposits. Beadell Resources’ “Handpump” project has seen the first intersections of economic gold mineralisation in the Musgrave.

The tenements are prospective for nickel, copper, Platinum Group Element’s (PGE), gold and iron.

Many of the gravity and magnetic anomalies identified by majors BHP Billiton and Anglo Australian are located on the project. None of these have been tested by drilling. Cassini looks forward to commencing exploration or partnership opportunities on successful grant of the tenements.

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.

CAMAC Energy Inc.  has announced it has signed an agreement with Sander Geophysics Limited (“SGL”) to shoot airborne gravity and magnetic geophysical surveys on its Kenya onshore Lamu Basin Blocks L1B and L16 (“Blocks”). The data acquisition will cover the entire 12,197 square kilometers in Block L1B and the entire 3,613 square kilometers in Block L16, exceeding the first exploration period’s gravity and magnetic survey requirements for each Block.

The results of the airborne gravity and magnetic survey will be used to optimize the placement of 2-D seismic lines by identifying faults, basement structures and intra-sedimentary volcanic layers and/or intrusions. Airborne gravity and magnetic data combined with 2-D seismic has been utilized to identify successful exploration targets in East African Rift Basins by regional operators Heritage, Tullow and Africa Oil. The Company expects SGL to commence data acquisition in the second quarter of 2013 and provide initial results in the third quarter of 2013.

Founded in 1956, the Ottawa-based SGL provides worldwide airborne geophysical surveys for petroleum and mineral exploration, and geological and environmental mapping. SGL has operated on every continent including Antarctica, and under diverse conditions ranging from the tropics, deserts, mountains and offshore.

“Executing this agreement with SGL is an important milestone for our Kenya exploration program,” said Senior Vice President of Exploration and Production Segun Omidele. “These gravity and magnetic surveys will satisfy the first requirement of the first exploration period, and most importantly, will allow us to delineate an optimal 2-D seismic program on the Blocks. This is the first step to unlocking the high potential value of our onshore Kenya acreage.”

Often not given its due in oil and gas geophysics, knowledge of basement geology can be critical to exploiting reservoirs including the unconventional.

New Approach to Basement Studies for Oil and Gas Explorers

Silver Spruce Resources Inc.

Highlights

• Sinuous magnetic low, possibly tracing the alteration zone, joins the Big Easy and ET zones, 3.5 km apart

Silver Spruce Resources Inc. reports on the final results of the high resolution, magnetic / VLF-EM survey and check sample results for diamond drilling carried out on the road-accessible, Big Easy gold/silver prospect in eastern Newfoundland. The Big Easy (BE) prospect is an extensive, altered (silicified) system that covers an area of approximately 1.7 km by up to 300 m wide which was drilled in 2011 and 2012, giving significant gold (Au) and silver (Ag) values in several holes (news releases August 16, 2012 and June 7, 2011) defining a low sulphidation epithermal Au/Ag system. The less explored ET zone, 3.5 km to the south of BE, was discovered by prospecting in the south central part of the property in June 2011 and has recently been extended to a minimum 400 m strike length.

High Resolution Magnetic/VLF-EM Survey

The 349 line km survey covered the entire property at 70 m terrain clearance and nominal 300 m line spacing, with 200 m line spacing over the known mineralization at the BE and ET zones. The results show magnetic lows, most likely representing the alteration coincident with the mineralized zones at both the BE and ET zones. These two established zones are joined by a sinuous magnetic low, which may represent alteration/mineralization linking the two known zones. The overall sinuous nature of the magnetic low is believed to be related to crosscutting faults, which may offset the alteration system as shown by magnetic highs representing mafic dikes emplaced along ENE and NW trending structures. The VLF-EM survey shows the ENE and NW trends as conductive zones, most likely representing water filled shear systems. The airborne data will be incorporated in the database for the area to plan for further exploration in 2013.

“The significance of the probable continuation of the alteration/mineralization over the 5 km plus strike length from the Big Easy to the ET zone is that the trend is becoming more defined as we continue exploration along the strong, extensive, mineralized alteration zone – which has only been tested by 12 drill holes over 1.2 km at the Big Easy itself, in the northern part of the property,” says Peter Dimmell, President and CEO of Silver Spruce Resources. “The Big Easy-ET trend is intensely altered with strong silicification and the strength of the system, coupled with the results from the early stage drilling at Big Easy, indicates that we have the potential for a large deposit that could be of interest to a major gold/silver producer.”

Diamond Drill Hole Check Analyses

Results have been received for the area of questionable results in Au only, noted in the first check sample analyses received (news release October 18, 2012). This “gold anomalous” area had been flagged in the original results as an outlier, as it gave only low Ag values in comparison to most of the other significant Au/Ag zones which were duplicated, although with “nugget-type” effects in the check sampling. Two check samples from section 101 to 112.25 m in DDH BE-12-10 gave values of 28 and 64 ppb Au, in comparison to the two original samples which gave values >1 g/T and the overall section from 101 to 112.25 m (11.3 m), giving 0.8 g/T Au and 3.8 g/T Ag. Subsequently, the rest of the rejected samples from this section were re-analyzed as check samples at a second laboratory, with similar results as the first set of check samples. The pulps from these re-analyses were then re-assayed at the original laboratory, where they found similar results indicating only background Au values throughout the section in question. None of the high Au values were duplicated and assays generally gave near background values (<70 ppb Au), indicating a problem in the Au analysis at the original laboratory. Interestingly, the highest check sample Au value was 150 ppb Au in the sample from 111.5-112.25 m, which gave 2279 ppb in the original analyses. The Ag values were 7.4 and 8 ppm respectively in this sample interval, the highest Ag values in this section and generally reflective of Au/Ag association throughout the Big Easy core sampling. The originating laboratory is still trying to determine how the spurious results occurred; however, to date no explanation has been brought forward.

Gold Dynamics Corp. contracted with Geotech Ltd. to complete a helicopter borne Versatile Time Domain Electromagnetic (VTEM Plus) and Horizontal Magnetic Gradiometer Geophysical Survey on the Hoyle North Palladium-Platinum-Gold Project located in Timmins, Ontario. A total of 84 line kilometers of geophysical data were acquired, flown at 100 meter spacing on the property.

Analysis of the preliminary data from the VTEM Plus indicate mineralized targets exist in the eastern portions and also a mineralized trend from the southeast to the northwest of the property at approximate depths of 200 meters. The survey also identifies a system of dykes which are very common in mineralized zones on this trend and are also common to the known geology of this area.

Further results and analysis are expected in the next few weeks. This information will be evaluated to select targets for ground follow-up in order to help prioritize anomalies for drilling.

Gary Kirk, CEO/President of Gold Dynamics Corp. said, “I am extremely pleased that we were able to contract with Geotech Ltd. who are a leader in their field, utilizing state of the art technology to help us build our base of knowledge on the Hoyle North project. With targets in hand, knowing the depth and location of these targets brings us much closer to finally drilling. The known geology common to the areas where other major international mining companies (Goldcorp, Xstrata Copper, Lakeshore Gold and Brigus Gold), whom are adjacent to our project, are currently producing large quantities of gold and other precious metals out of geologic structure very similar to what the VTEM Plus has identified in ours; is very encouraging for us.”

The Hoyle North property is contiguous to Goldcorp’s Hoyle Pond mine and is within short distances to significant resources such as Owl Creek and Bell Creek. The Hoyle North property remains relatively unexplored near to expansive mining and exploration efforts by significant companies such as, Goldcorp, Xstrata, Lakeshore Gold, San Gold, Osisko Mining and VG Gold and others.

Citation Resources Inc. announces preliminary results of its airborne versatile time-domain electromagnetic (“VTEM“) survey completed in October 2012 over a substantial portion of the Biricu Gold Project located within Mexico’s Guerrero gold belt.

The VTEM survey was conducted by Geotech Ltd. and covered approximately 1,400 line kilometres at 150 metre spacing over three specific high-priority areas of the concession within a broader survey coverage at 200 metre spacing. Condor Consulting Inc. experts in the field of airborne electromagnetics, has been retained to perform a detailed interpretation of the results and their final report regarding the significance of the survey is still pending.

The preliminary interpretation by Condor has identified 19 potential target zones as defined by conductivity and magnetic geophysical anomalies on the Biricu Project. Six of these target zones are aligned along a 5 kilometer northeast trending corridor, which to date has only been partially ground tested. A field crew has been mobilized to conduct further mapping and sampling over the geophysical anomalies in order to prioritize areas for possible drill testing. Upon receipt of the final geophysical interpretation, the results will be integrated with the analysis of the field work completed and drill targets will be prioritized. The details of the final results will be presented in a future news release.

Bellhaven Copper & Gold Inc. reports the commencement of the previously announced ZTEM (airborne electro-magnetics) survey over the entire La Mina property (1,800 Ha). The survey is also being extended to include an adjacent concession, which the Company is currently in discussions to acquire. The work is contracted to Geotech Ltd., a Canadian geophysical survey company specializing in leading edge airborne technology. The survey is designed to help refine the targets at La Mina, with a particular emphasis on the Garrucha and Cristalina target areas.

The helicopter-borne geophysical survey will result in approximately 132 line kilometres of data along east-west lines, spaced at 200 metres. The Z-TEM Electromagnetic (EM) system is an innovative technique making use of naturally occurring or passive EM fields from worldwide thunderstorm activity as the source of transmitted energy. The passive source combined with a proprietary receiver design, advanced digital electronics, and signal processing results in low noise levels, exceptional resolution, and unparalleled depth penetration. It has been used successfully to identify and map porphyry style mineral systems from Alaska to Chile.

Patrick Highsmith, Bellhaven’s CEO, commented on the program: “We are pleased to bring the ZTEM technology to the Middle Cauca Belt for the first time. It is a proven technique for porphyries in the Americas. This will enable us to prioritize existing geochemical and magnetics anomalies, including on concessions that we are in negotiations to acquire. This is a very cost effective tool that adds immediate value in an emerging mineral district such as La Mina. By sharing the mobilization and some of the administrative costs with neighboring explorers, we have made it even more cost effective.”

Discussion of ZTEM Survey

The survey is expected to identify conductive and resistive features that are associated with large mineral systems such as gold-copper porphyries from surface to considerable depth. The electromagnetic data is sensitive to sulfide minerals, as well as silicification and clay alteration; all of which are associated with the porphyry and epithermal deposits in the Middle Cauca Belt. This will be an important addition to the magnetics data that drove the initial discoveries. The EM data will advance the geologists’ knowledge of the known resource areas, particularly at depth, but it will also upgrade the targeting arsenal elsewhere on the property. This work will also enhance understanding of large structures in the district. Many of these structures have previously been mapped from both surface exposures and drill intercepts; and the Bellhaven team is focused on their importance in controlling mineralization.

The survey crew arrived on site November 17, and began conducting reconnaissance flights a few days later. They are currently flying the survey as cloud cover permits. It is expected that a total of 6 to 8 days of favorable conditions is needed to complete data collection, so the survey should be completed before the end of December.

La Mina Porphyry Gold Copper Project

La Mina is a resource stage porphyry gold-copper project located in the Middle Cauca volcano-plutonic belt in the Department of Antioquia about 45 km southwest of Medellin. The Middle Cauca belt is known to host large porphyry gold deposits such as AngloGold’s La Colosa Deposit (24 Moz Au) and Sunward Resources’ Titiribi Project (11 Moz Au).

Exploration Targets

The La Mina concession includes almost 2,000 hectares. A number of anomalous features are evident from the initial airborne magnetic survey, completed by AngloGold. As surface sampling and drilling progressed, a number of multi-faceted targets emerged. Through the first half of 2012, a total of four known mineralized porphyry systems have been identified; two of these deposits are host to NI 43-101 compliant inferred mineral resources. The two remaining known porphyries will be the focus of future drilling, meant to advance these prospects to the resource stage as well. The exploration pipeline at La Mina includes a number of other targets that, based on geology, geochemistry and geophysics, have characteristics similar to porphyry or porphyry related deposits. There are at least 7 of these discrete targets undergoing additional work, but they have not yet been drilled. The figure below shows total magnetic intensity (reduced to pole) from an airborne magnetics survey. Many of the targets are identified on this map; and more detailed information is available below.

Premium Exploration Inc.  reports that a ground-based Induced Polarization (“IP”) geophysical survey at the Idaho Gold Project (“IGP”) has successfully outlined a new target at the X Zone. This new IP target exhibits coincident highly anomalous gold-in-soil and airborne mag/EM signatures. These characteristics are similar to those associated with the three known deposits along the IGP and suggest potential for the discovery of new gold mineralization at the Idaho Gold Project. Details.

This is the 12^th advanced target identified on the project. These twelve targets all exhibit highly anomalous geochemical signatures associated with strong airborne magnetic and electromagnetic and ground IP geophysical anomalies. The majority of the targets are yet to be drill tested.

Anglo Swiss Resources Inc. has announced plans to commence an airborne electromagnetic (EM) survey over its Blu Starr Flake Graphite Property located near Nelson in southeastern BC. The property adjoins Eagle Graphite Corporation’s flake graphite operation which is one of only two natural flake graphite mines in North America. Next to Eagle Graphite, Anglo Swiss holds the largest land package covering 6,473 hectare (~65 sq. km) in the southern part of the favourable Valhalla Metamorphic Complex (see attached maps).

The planned ~550 line-kilometre survey will complete EM geophysical coverage over the entire property expanding on the 2010 survey completed by the Company. The earlier survey outlined a three kilometre long, shallow south-dipping conductor on the north side of Perry Peak which correlates well with numerous outcrops of large flake graphite occurrences known as the Tedesco showing. At this time the total thickness of the graphite bearing units is unknown as this conductor has not been drill tested. The new EM survey will cover the southern half of Perry Peak and central part of the property with the goal of identifying the possible southern extension of Tedesco as well as new large EM conductors. Aeroquest Airborne Limited will be conducting the EM survey utilizing the AeroTEM IV system.

Geology – Property

The varied geology of the property has been extensively mapped. Metamorphic rocks of the Valhalla Complex in the Passmore Dome area belong to the “upper sheet,” lying between the Airy quartz monzonite sheet dated at 62 Ma and the underlying Mulvey granodioritic gneiss sheet dated at 100 Ma. Graphite and minor sulphidebearing carbonate and calc-silicate layers lie at a structurally higher level in the the upper sheet, than that of the cordierite (iolite) and corundum (sapphire) bearing lenses that appear to lie within or near to the Gwillim Creek shear zone.

The Tedesco area geological map units cannot be directly correlated with other areas of the Slocan property. The Tedesco area hosts distinctive graphitic marble layers not known to occur on other areas of the property. During mapping and surveying, five distinct rock unites were observed.

Research –  Geophysical Survey

IP surveys of this property have identified a pronounced anomalous chargeability, possibly attributed to flat-lying marble or calc-silicate horizons containing concentrations of conductive graphite, possibly with other associated sulphide minerals such as pyrrhotite and pyrite.

The total magnetic field survey produced dissimilar but conspicuous magnetic features that might be attributed to either magnetite or pyrrhotite in the host rock.

CuOro Resources Corp. announces that Geotech Ltd. of Aurora, Ontario (“Geotech”) has been engaged to complete a 416 line-kilometre, helicopter-borne versatile time-domain electromagnetic (“VTEM”) survey of the Santa Elena Copper-Gold Project, in Antioquia Department, Colombia.

Geotech’s VTEM system has been shown to be excellent at identifying conductive, massive-sulphide bodies as well as mapping lateral and vertical variations in resistivity. The VTEM system is also equipped with a high sensitivity magnetometer which can aid in mapping geologic structure and lithology.

The survey is expected to be completed during October 2012. The Company will immediately investigate any targets generated by the survey with exploration and drilling.

Santa Elena Overview

Santa Elena is classified as a bimodal-mafic VMS deposit. This type of deposit is similar to that found in many of the major district of the Precambrian Shields of Canada, Western Australia, and Scandinavia, as well as the Urals and in the Cretaceous of Peru. The latter is comprised of the giant Tambo Grande deposits; TG1 and TG3, adjacent deposits comprising a single ore system contain a non 43-101 compliant resource of over 138 MT of 1.3% Cu and 1.1% Zn. The Tambo Grande deposits are in a very similar setting to the Santa Elena occurrence, and given that both are in what appears to be an oceanic back-arc setting, this district may be a model for Santa Elena. It is important to note that VMS deposits almost always occur in districts, and that their sizes are log-normally distributed.

The concessions contain 1,287.5 hectares near the north end of the Antioquia batholith, at the intersection between the San Pablo formation (Cretaceous marine sediments) located to the north, the basaltic volcanic flows located to the west, and the Antioquia batholith quartz-diorite complex to the east.

The infrastructure is excellent and includes paved road access, two hydroelectric plants within 5 km, and abundant water supply.

Geological mapping and sampling has identified 3 VMS areas of outcropping (TEM-1, TEM-2, and TEM-3) all of which coincide with historical geophysical anomalies. Several new mineralized outcrops have been located recently south of the known VMS outcrops.

Recently completed geophysical surveys have validated the historical data, as well as produced many new targets which will be drill tested.

Summary of Geophysics

A surface geophysical TEM survey at 50 m intervals was conducted on a selected area of the property where outcropping mineralization was visible. The survey was conducted by VAL D’OR Geophysics for Noranda Mining and Exploration Inc in 1996-1997.

The historical ground geophysics had identified 4 strong conductors with good vertical extent, 3 of which are coincident with the TEM-1, TEM-2, and TEM-3 outcrops.

An airborne magnetometer and radiometric survey was flown in August 2011. These surveys were followed-up by ground based induced polarization and resistivity surveys. These surveys validated the original survey data, and also generated several new drill targets which are currently being drill tested.

The company plans to initiate down-hole TEM surveys along with additional induced polarization and resistivity surveys in January 2012.

Silver Spruce Completes Airborne Survey and Receives Check Assays for the Big Easy Gold/Silver Property, Eastern Newfoundland

Silver Spruce Resources Inc. announces that the high resolution magnetic / VLF-EM airborne survey has been completed and preliminary results received on the road-accessible, Big Easy gold/silver property in eastern Newfoundland. The Big Easy prospect is a large, altered (silicified) system that covers an area of approximately 1.7 kilometres by up to 300 metres wide.   The prospect was drilled in 2011 and 2012 — a total of 12 holes over a 1.2 km strike length, giving significant gold (Au) and silver (Ag) values in a number of the drill holes (news releases September 18, 2012, August 16, 2012 and June 7, 2011).

Airborne Survey
The airborne, high resolution magnetic / VLF-EM survey was carried out in late September by Terraquest Ltd. of Mississauga, ON.    The aim of the survey was to improve the understanding of the geological setting of the area by a lithological/structural interpretation based on the survey results, drilling and surface geology.

The preliminary magnetic data shows a broad, NNE (025 degrees) magnetic high trending through the main portion of the claim group with narrow linear, NNE trending magnetic lows within the overall magnetic high.   The magnetic  lows are offset by linear zones and possible dikes / faults, trending NNW (340 degrees). A sinuous magnetic  low joins the BE and ET zones, continuing to the south of the ET zone.    The preliminary VLF-EM data shows NNE and NNW trending, as well as a number of E-W to ENE-WSW trending conductive zones cutting through the property.

“We are pleased with the resolution of both the magnetic and VLF-EM data.    Based on what we are able to tie into our existing geological and structural compilation, the final results should enable us to better target continued exploration, including drilling,” states Peter Dimmell, President and CEO of Silver Spruce Resources.

Line spacing was 200 m in the known mineralized areas (Big Easy and ET) and 300 m over the rest of the property, at a mean terrain clearance of approximately 70 m. The survey was flown using E-W lines and N-S tie lines for a total of 349 line km. The VLF-EM used two orthogonal receivers, with the main transmitter Cutler, ME.

Dalradian Resources Inc. has received final assays from hole 12-CT-162, which was drilled to test a geochemical anomaly from a recently released survey. The hole is located approximately 1700 metres along trend from the Company’s wholly owned Curraghinalt deposit in Northern Ireland.

From previous news about the property:

The recently-completed 1,034.3 line kilometre VTEM and magnetics survey that was flown along 10 km of the Curraghinalt Trend, which is both over and along strike from the Curraghinalt gold deposit. The tightly spaced survey (50m line spacing) will assist with targeting further drilling based on an improved three dimensional understanding of the geology, structure and alteration zones associated with mineralization.

The Curraghinalt Deposit is a mesothermal gold system consisting of a series of approximately east-west trending gold bearing high grade narrow veins in meta-sedimentary host rocks.

Purepoint Uranium Group Inc. has released the results of this summer’s geophysical survey at its 100% owned Turnor Lake Project in Saskatchewan’s Athabasca Basin. The induced polarization survey has moved the exploration of this property further north, covering the high-priority Anvil South uranium target area.

____________________

-     The induced polarization (IP) survey was conducted over the Anvil South grid with the purpose of outlining possible low apparent resistivity chimneys (LARCs) in the sandstone. LARCs are considered to be excellent drill targets when found within a favourable geologic setting as they represent potential zones of hydrothermal alteration.

“The IP survey data is of high quality, free of noise and aligns well with historic drilling data, unconformity depth, and overburden thickness,” said Roger Watson, Purepoint’s Chief Geophysicist. “Numerous geophysical LARCs have now been interpreted; many of them correlating with an untested, well-defined electromagnetic conductor.”

Highlights:

• Low apparent resistivity chimneys (LARCs), possible zones of hydrothermal alteration, have been outlined within the Anvil South zone and correspond with untested EM conductors;
• The resistivity survey successfully identified a LARC that corresponds with altered sandstone intersected by historic hole OD-1 that also returned 468 ppm U over 3.4 m;
• The geophysical results collected by Purepoint at Anvil South, which includes resistivity, gravity, and highly detailed airborne electromagnetics and magnetics, have been compiled with all available historic data identifying five new high priority drill targets;
• A strong geochemical anomaly of uranium, nickel and cobalt was outlined at the Klaproth South target in 2011 and verified by re-sampling in 2012.

Anvil South

The Anvil South grid covers over four kilometers of electromagnetic (EM) conductors that were outlined by a VTEM airborne survey in 2006. The EM conductors show significant offsets interpreted to be caused by faulting. Purepoint conducted a gravity survey over the Anvil South grid in 2008 but has not yet drill tested geophysical targets in this area.

During August 2012, over thirty line-kilometers of IP surveying was completed at Anvil South by Peter E. Walcott & Associates Ltd. of Vancouver, BC. The data was inverted by Purepoint using IP inversion software developed by the University of British Columbia. The IP survey was successful in that well defined resistivity “chimneys” (LARCs) were identified in the sandstone. The Anvil South LARCs have now been plotted in relation to resistivity, gravity, EM conductors and magnetics and five priority drill targets have been identified.

The historic drill hole OD-1, drilled at Anvil South by the Saskatchewan Mining Development Corp. in 1985, intersected 3.4 m of 468 ppm U within a highly altered graphitic pelite immediately below the unconformity. Anomalous concentrations of arsenic, nickel and cobalt were associated with the alteration encountered in the OD-1 drill hole.

Turnor Lake

The Turnor Lake Project is 100% owned by Purepoint. This 9,705 hectare property covers graphitic electromagnetic (EM) conductors that are directly associated with high grade uranium showings on adjoining properties, namely Cameco’s La Rocque occurrence (up to 33.9% U3O8 over 5.5 m) to the west and Areva’s HLH-50 intercept (5.2% U3O8 over 0.38 m) located to the south. The project lies in close proximity to several uranium deposits, including Roughrider, Midwest Lake, McClean Lake and Eagle Point, and has a shallow depth to the unconformity of less than 200 metres in most areas.

A series of detailed geophysical surveys have been conducted on the property since November 2006 and numerous drill targets, including EM conductors and structurally complex areas having evidence of intersecting structures, remain untested. Drill targets have now been prioritized with the completion of the 3D Targeting Workflow Process by Mira Geoscience.
