Positive Developments Continue in southwestern Newfoundland

Posted by on Thursday, 19 May, 2011

Private Canadian Junior Mining Company Triple Nine Resources Ltd. (TNR) owners of the Four Corners Iron Ore – Titanium – Vanadium Property 23 kms east of the TCH along the Burgeo Paved Highway in southwestern Newfoundland announces significant developments for the property and it’s corporate business plan. Company Chairman and CEO Mr. Len Muise states that he is very pleased with the latest developments TNR has achieved to date in 2011 and which are summarized below.

In late February an independent consultant, based in Europe, visited the Four Corners Project (FCP) and confirmed the 2010 surface, drilling and airborne survey results that is suggesting a large, bulk tonnage deposit could exist on the FCP.

The first phase of exploration for this year is an airborne geophysical survey, which has been awarded to Geotech Ltd. of Aurora, ON. The survey planned for next week will cover the area of new staking extending 21 kms west of last years 6 km long Magnetic (MAG) anomaly. This highly anomalous region, based on drilling and surface trenching results, is now known to host significant concentrations of iron ore, titanium and vanadium mineralization. Geotech will be using their helicopter borne VTEM PLUS or Versatile Time Domain ElectroMagnetic (EM) system, which they advertise “as the most innovative and successful airborne EM system to be introduced in 30 years”.

In early July TNR will commence the 2011 core-drilling program for further testing of the mineralization intersected during the 2010 drilling. Up to 40 drill sites are planned to test the strike and down dip extensions of the Keating Hill Mineralized Zone. In concert with the drilling there will be a program of prospecting and excavator trenching designed to test the indicated extension of the more than 6 km long MAG anomaly. Last years prospecting up to 2 kms west of the MAG anomaly identified highly mineralized samples further confirming the potential for significant strike extension to the west (ref. press release November 9, 2010).
Geology and field technical support crews are in place and will be mobilizing to the project site within the next couple of weeks. Work has now commenced on recommissioning and expanding the existing trailer base camp facilities to accommodate the larger crew necessary for this years expanded work program. Geotech has advised the preliminary results from the airborne survey should be available by mid June and this information together with an upgraded interpretation and modeling of last years airborne survey results will assist greatly with directing the drilling and other phases of the planned 2011 exploration program.


Progress on Semple-Hulbert and Butler Lake properties with geophysics

Posted by on Monday, 9 May, 2011

MacDonald Mines Exploration Ltd. announces the commencement of a 3,000 meter diamond drill program on its Semple-Hulbert Property in the James Bay Lowlands of Northern Ontario. The program follows the Butler Lake drill program which consisted of 3800 metres of drilling over 17 diamond drill holes targeting volcanogenic massive sulphide (VMS), nickel-copper-platinum group element (Ni-Cu-PGE), and vanadium targets.

The Semple-Hulbert drill program will focus on high priority Ni-Cu-PGE targets in a never-before-drilled geologic complex that geophysically has been interpreted to resemble the Voisey’s Bay Ni-Cu deposit.

Semple-Hulbert Property

Drilling has commenced on the highly prospective Semple-Hulbert Property, located within the traditional territory of the Kasabonika Lake First Nation.

The Semple-Hulbert claim group was initially targeted by MacDonald’s because it had:

The strongest regional magnetic anomaly;

The strongest regional gravity feature;

Been mapped as an ultra-mafic feature on regional geology maps.

The primary catalyst for this information was a Geotech VTEM survey of the claim group in 2008, interpreted by Quentin Yarie, P.Geo., Hadyn Butler, P.Geo. and Larry Hulbert, D.Sc.

Geophysical Interpretation of Semple-Hulbert

- The geophysical data exhibits the characteristics of an intact intrusive body.

- Modeling of the magnetic data outlined a magnetic feature, which is dimensionally about >10km long by 3-4km wide and extending to at least 3km below surface.

- 8 electromagnetic targets (conductors) located within the interpreted intrusive are targeted for drilling;

- Within this body the magnetic response varies spatially – suggesting multiple geologic events.

- This interpretation fits the analogy to the Voisey’s Bay deposit; that being multiple magma pulses over time.

- The modeling also exhibits features similar in nature to four of the Voisey’s Bay intrusive components; the Eastern Deeps, Discover Hill Zone, the Ovoid, and the Reid Brook Zone (feeder sheet).

Butler Lake Property

The recently completed drill program on the Butler Lake Property consisted of 17 diamond drill holes, 7 targeted VMS mineralization, 2 targeted Ni-Cu-PGE mineralization, and 8 targeted vanadium.

VMS – (Copper/Zinc)

Stringer, semi-massive, and massive sulphides consisting of pyrite, pyrrhotite, chalcopyrite, and sphalerite were intersected in 6 of the 7 VMS drill holes. Samples have been submitted to Activation Laboratories Ltd. (ActLabs) in Thunder Bay for analysis, with assay results expected by May 16.

Nickel

Disseminated magmatic sulphides were intersected within each of the 2 Ni-Cu-PGE drill holes. Samples have been submitted to ActLabs for analysis, with assay results expected by May 16.

The Company will be conducting the next phase of drilling on the Butler Lake property once all of the current exploration data and assays have been received and analyzed.  Geochemical and geophysical signatures will be utilized to direct the drill program which is anticipated to begin in July, 2011.


Mag for Iron-T Vanadium Project at 11630000 Tonnes

Posted by on Sunday, 21 November, 2010

Apella Resources Inc.  announces that Abitibi Geophysics Inc. from Val d’Or, Quebec has completed the contracted 250 line km Magnetic-GPS survey on Apella’s Iron-T Vanadium-Iron-Titanium project near Matagami, Quebec.

Patrick D. O’Brien, ICD.D, Apella’s CEO stated, “This survey is expected to increase the number of drill-ready targets significantly.”

The magnetic survey comprised approximately 250 km of transversal lines, base lines and tie lines over the entire western part of the property from Shallow Lake to the Bell River. This represents about 50% of the total area of the Iron-T Project. The central part of the Iron-T which was the subject of the 2009-2010 exploration drilling campaigns, as well as the eastern part, have been surveyed by Apella over the years from 2007 (17 original claims) to March 2010.

Now that this survey is complete the entire Iron-T project consisting of 146 claims totaling 3,995.57 hectares has been covered by ground magnetic survey.

Results of the new magnetic survey will be available to Apella around the beginning of December 2010 and are expected to provide an abundance of drill targets which collectively, once drilled, should confirm the size of this World-Class magmatic V-Fe-Ti oxide deposit(s) covering the Iron-T.

In the past, the Iron-T area was covered by a regional airborne magnetic and electromagnetic INPUT MK VI survey which was conducted in 1977. Regional magnetic data over the Iron-T project from that airborne survey was acquired at a nominal lines spacing of 200 metres and a nominal mean terrain clearance of 125 metres. In addition, the western half of the Iron-T Vanadium-Titanium-Iron property, now being ground surveyed by Apella was covered by a regional airborne gradiometric survey carried out in 1984. Magnetic data in that survey was acquired at a nominal lines spacing of 300 metres and a nominal mean terrain clearance of 150 metres. The two airborne magnetic surveys outlined a broad magnetic anomaly up to 4 000 nT above the background level which is continuous over some 25 km in a WNW direction.

To date, the ground magnetic surveys undertaken by Apella have shown a direct relationship with the Vanadium, Iron and Titanium mineralization discovered. They have also provided more precise locationing of the anomalies and more accurate shapes of the targets.

This latest ground magnetic was carried over lines at 100 spacings with readings every 2 seconds. The diurnal corrections are made with a synchronized Mag base station. Observation of the Total Magnetic Field (TMF) was recorded and will be treated with Geosoft software. The Vertical Gradient will be calculated from the TMF.

The survey was also planned to confirm the lengths and widths of a number of specific airborne anomalies. It covered a 3 km long NW oriented magnetic axis which starts near the southwest shore of Shallow Lake and which seems to joins the main magnetic axis. This magnetic “South Branch” is about 3 km long and has never been drill tested.

In other news, Apella has received from Viasat Geo Technologies Inc. all data permitting it to address a topographic map of the whole Iron T mining property. The data includes geo-referenced rivers, roads and lakes; as well as level curves at 1 m interval. The base of this topographic map is a mosaic of satellite images from Worldview-2 at 50 cm resolution. The base topographic map was released in jpeg format at a scale of 1: 25 000. The cartographic reference system used for local mapping and drawing is Universal Transverse Mercator projection for Canada (NAD 83), Zone 18.

This work will provide the exploration team with the tools necessary to prepare the longitudinal and transversal geological sections with an accuracy of 0.35 m in all directions. Those sections will be used for 3D modelling and for the ongoing resource calculations; as well as provide qualification with a better accuracy.

In addition, this topographic information will later be used by the mining engineers for future open-pit design and planning, the localisation to the concentrator and waste piles and all infrastructures necessary for a mining operation (power line, telecommunications, water supply, drainage, etc…).

The present satellite image taken in August 2010 clearly shows all drill sites and strippings made since 1998. The grid of cut lines made in 2009 is also well visible.

The Iron-T Vanadium-Titanium-Iron property is located in the Matagami area in the west-central part of the Province of Quebec, Canada, approximately 780 km north of Montreal. Matagami, situated in the administrative region of Northern Quebec, is the major town in the area and can provide housing, servicing, supplies, consumable and transport facilities including railway access for an efficient mining operation. The property is accessible via Matagami located approximately 780 km of Montreal, 250 km from Val d’Or and 185 km from Amos along regional highways. Matagami is accessible via Regional Highway 109 which links Amos to the Bay James Highway. The central part of the Iron-T Vanadium-Titanium-Iron property is located 10 km ESE of the town of Matagami. Access to the property itself is via all-weather gravel road N805 which links Lebel-sur-Quévillon to Matagami.


New staking increases with airborne geophysics

Posted by on Tuesday, 9 November, 2010

Triple Nine Resources Ltd announces that it had increased the size of the Four Corners Vanadium – Titanium – Magnetite (Iron Ore) Project with the staking of 70 full sized mining claims in 2 separate blocks.  These claims, which increase the total number of claims from 194 to 264 covering 16,566 acres (6707 hectares) add 8.5 kms of strike length to the project area that now exends 21 kms west of the Neils Prospect marking the eastern limit of the mineralized target zone.

Earlier this summer, prospecting and surface grab samples together with the Fugro airborne survey results confirmed the potential for the 5.6 km long target zone to extend west (ref Sept 29/10 release).  As a result, a group of new claims was staked in July and initial prospecting and sampling identified significant mineralization in outcrop and boulders up to several kms west of the target zone.  These newly identified mineralized sites yeilded a high range of values with a best assay of 0.263% vanadium pentoxide, 14.64% titanium oxide and 50.30% iron oxide.

This recognition of significant strike length to the west and the potential for continuation of the minerlization beyond the 9 kms now inferred from the earlier prospecting and surface sampling prompted Triple Nine to add the 2 new claim blocks.

Triple Nine Resources Ltd.  releases the details of the latest exploration results from its 2010 exploration program just completed on the Four Corners Vanadium – Titanium – Magnetite (Iron Ore) project situated along the Burgeo Highway in Southwestern Newfoundland.

The company advises the analytical results from the first shipment of 136 drill core samples completed at Actlabs, Ancaster, ON together with the final release of airborne data acquired during the Fugro helicopter borne electromagnetic survey completed by Fugro Airborne Surveys of Mississauga, ON in early June are very positive in supporting the model for a large tonnage resource on the Four Corners Project.

The assay results from the 136 samples, which are from sections of 3 of the 5 holes completed in October, confirm the continuity along strike and down dip of the mineralization detailed during the July 2010 surface trenching and channel sampling program, which returned previously recorded weighted average grades of 23.00% Total Iron (Fe2O3 T), 5.70% Titanium Oxide (TiO2) and 0.13% Vanadium Pentoxide (V2O5).

EM anomalies are typically produced by concentrations of sulphide mineralization, which can be associated with magnetite – ilmenite rich deposits.  Because of the unique nature of the EM response, first identified in the early June 2010 survey, Fugro subsequently carried out modeling of the responses, which based on a case study in a similar geological environment shows a probable source for the anomaly at a depth greater than the current drilling.  (The responses from the magnetic survey also show that the mineralization dipping at 55° west probably extends down dip for at least 1000 metres – 3300 feet).  Hole FCP-04-10 is the deepest hole drilled to date testing the zone down to a vertical depth of 220 metres – this hole was stopped in semi-massive to massive magnetite.


Extensive 250 km Iron-T Mag Survey Underway

Posted by on Sunday, 31 October, 2010

Apella Resources Inc.  announces  that the company granted Abitibi Geophysics Inc. from Val d’Or, Quebec, a contract to conduct an extensive 250 line km Magnetic-GPS survey on Apella’s Iron-T Vanadium-Iron-Titanium project near Matagami, Quebec.

From the positive drill results obtained to date coupled with data from earlier airborne surveys covering the western part on the Iron-T Project the company has concluded that the rich mineralization discovered to date extends over the entire western extension of the Iron-T. Based on these conclusions, the rich mineralization identified to date would extend over a multi-kilometer strike length and be open in all directions and at depth.

The magnetic survey now underway will comprise about 250 km of transversal lines, base lines and tie lines and is planned to cover the entire western part of the property from Shallow Lake to the Bell River. This represents about 50% of the total area of the Iron-T Project. The central part of the Iron-T which was the subject of the 2009-2010 exploration drilling campaigns, as well as the eastern part, have been surveyed by Apella over the years from 2007 (17 original claims) to March 2010.

Once this new survey will be completed, the entire Iron-T project which currently consists of 146 claims totaling 3,995.57 hectares will have been covered by a ground magnetic survey.

Results of the new magnetic survey will be available to Apella at the beginning of December 2010 and will provide considerable abundance of drill targets which will confirm the size of this World-Class magmatic Fe-Ti-V oxide deposit.

In the past, the Iron-T area was covered by a regional airborne magnetic and electromagnetic INPUT MK VI survey which was conducted in 1977 (Questor Surveys Ltd. ?). Regional magnetic data over the Iron-T project from that airborne survey were acquired at a nominal lines spacing of 200 metres and a nominal mean terrain clearance of 125 metres. In addition, the western half of the Iron-T Vanadium-Titanium-Iron property, now being ground surveyed by Apella was covered by a regional airborne gradiometric survey which was carried out in 1984. Magnetic data in that survey was acquired at a nominal lines spacing of 300 metres and a nominal mean terrain clearance of 150 metres.

The survey under progress is planned to confirm the lengths and widths of the airborne anomalies. It will also cover a 3 km long NW oriented magnetic axis which starts near the southwest shore of Shallow Lake and which seems to joins the main magnetic axis. This magnetic “South Branch” is about 3 km long and has never been drill tested.

The Iron-T Vanadium-Titanium-Iron property is located in the Matagami area in the west-central part of the Province of Quebec, Canada, approximately 780 km north of Montreal.


HIGH GRADE INFILL DRILLING RESULTS AT EAGLE’S NEST

Posted by on Thursday, 14 October, 2010

Noront Resources Ltd. reports the remaining assay results from the infill drilling program at the Eagle’s Nest deposit at the Company’s McFaulds Lake Project in the James Bay lowlands, Ontario.

Noront’s President and CEO, Wes Hanson, states: “The Company is pleased with the results. Nickel, copper, platinum and palladium grades were higher than expected in the majority of the holes completed. Most of the holes targeted the inferred resource and the Company believes that a large percentage of the inferred resource has been upgraded as a result of this drilling.”

Four Corners Project – surface and airborne surveys

Posted by on Wednesday, 29 September, 2010

Triple Nine Resources Ltd. updates shareholders on the latest results from 2010 exploration program on the Four Corners Vanadium – Titanium – Magnetite (Iron Ore) Project.  During the fieldwork, which is still in progress, TNR successfully completed an airborne magnetic and electromagnetic survey, trenching and channel sampling of bedrock, geological mapping and prospecting.  The different work phases all produced highly positive results that indicate the potential for outlining a major bulk tonnage resource of ore grade mineralization (overall these results from our first full exploration season have exceeded our expectations).

“We were fortunate in early June to contract Fugro Airborne Surveys to complete a 110 kilometre airborne survey over the project area.  (Fugro was in the area surveying for other mining companies thereby allowing TNR to avail of their services).  The Fugro survey has produced “exceptional” magnetic and electromagnetic responses over a 5.6 km (3.5 miles) strike length extending the strike length of 3.5 kms initially outlined during earlier ground magnetic surveys in 2009 and 2010.  Adding to the strike length by 2 kms increases the overall size of the target zone by almost 40%.”

This is a significant exploration result for the Four Corners Project, particularly as prospecting in the area of the strike extension has identified strong mineralization in grab samples of outcrop and boulders.  A suite of 18 samples assayed at Actlabs in Ancaster, ON yielded a high range of values with iron oxide (Fe2O3 T) averaging 31.55%, titanium oxide (T1O2) 7.00% and vanadium pentoxide (V2O5) 0.172%.  These are very robust mineral values and present another new and exciting target to explore.

TNRs 1000 metre first phase drilling program is nearing completion and the last of 5 holes will be completed this week.  “The success we have achieved in our surface and airborne surveys is continuing in our drilling as all 5 holes have interested the magnetite – titanium – vanadium enriched zones sampled during the surface sampling completed in July.  The results of the trench sampling and airborne surveys have greatly assisted in positioning the drill holes for testing this large target zone on the Four Corners Project.  The 2010 work program of airborne surveying, trenching, rock sampling and diamond drilling is generating a large database which will provide important information on the mineralizing nature and extent of the mineralized zone which is emerging to be a major resource potential.”


Airborne Mag-EM initiates the drilling at Four Corners

Posted by on Monday, 20 September, 2010

Triple Nine Resources Ltd. of Stephenville, NL is pleased to announce it has commenced the planned 1000 metre (3500 ft) drilling program on it’s Four Corners Magnetite – Titanium – Vanadium Project along the Burgeo Highway in southwestern Newfoundland.  The drilling program is following up on the highly positive results obtained from 1100 metres of surface trenching and 110 kilometres of airborne surveying completed during the summer work program.

A total of 351 channel samples from the surface trenches, assayed at Actlabs in Ancaster, ON, reveal there is an extensively mineralized zone at Four Corners that corresponds to a more than 6 kilometre (3 ¾ miles) zone of “exceptional” magnetic and electromagnetic airborne geophysical responses defined during the airborne survey.  These airborne results recently received by the company are greatly assisting in directing the first phase of drilling now in progress.

Company Chairman and CEO Len Muise advises that Triple Nine will release the details of the surface and airborne surveys at the upcoming Canadian Institute of Mining (CIM) Convention to be held at St. John’s from Nov 4 – 6 and also will be displaying the Four Corners drill core at this mining convention.

Airborne survey in the Lac Lablache

Posted by on Sunday, 14 February, 2010

Argex Silver Capital Inc.  reports that it has completed an airborne geophysical survey of its titanium, vanadium and iron ore properties in the Lac Lablache region on the North Shore of Quebec. A total of 418.5 kilometers was covered in this survey, comprising all of the Company’s claims in this region. The combined survey consisted of Magnetic, Electromagnetic and gamma-ray spectrometric surveys. This information will be integrated into the upcoming drilling campaign in the Lac Lablache area. The survey was completed by Geophysics GPR International Inc. a pioneer in applied geophysics in Canada, of Longueuil, Quebec.
