Investigator extends Paris gaiety

/in /by

THE DRILL SERGEANT: Investigator Resources has received the final batch of assays for a program of reverse circulation percussion (RCP) drilling the company completed at its Paris prospect, located on the Eyre Peninsula of South Australia in late February.

The company said the final batch of assay results has produced a number of high silver grades of up to 7,365 grams per tonne silver, some of which required several cycles of repeat assaying with higher level techniques including concentrate level assays being conducted in Vancouver.

The new high-grade silver intersections add to the mineralisation the company previously reported in February.

 In addition to the high-grade silver intersections previously reported for Lines 7, 8 and 9, key new intersections along the one kilometre length of the Paris target include:

North Eastern Zone

–    7 metres at 1,810 grams per tonne silver from 31m;

Western Zone

–    10m at 432g/t silver from 49m;

South Eastern Zone

–    19m at 965g/t silver from 42m;

Central Feeder Zone

–    14m at greater than 427g/t silver from 97m;

–    8m at 710g/t silver, 0.81g/t gold from 90m;

–    6m at 596g/t silver from 40m; and

–    12m at1.43g/t gold from 41m.

Investigator said the drilling had struck new high-grade intersections flat-lying manto-style sheets with extensions that still are yet to be drill-tested.

The company is excited by the recognition of potential vertical feeder structures including the Central Feeder Zone of at least 400m, which it considers could potentially add up to 900 metres strike length of high-grade tonnage to the Paris system.

“The recent inclined drilling intersected the Central Feeder structure largely missed by the initial vertical aircore drilling that otherwise made many silver hits in the flatter manto-style mineralisation,” Investigator Resources managing director John Anderson said in the company’s announcement to the Australian Securities Exchange.

“The new opportunity is for a three to seven metres wide vertical structure assaying over 400 grams per tonne silver similar to some of the better silver mines around the world.

“This interpretation offers depth extensions for high-grade silver mineralisation with increasing gold credits already evident in some of the intersections.

“Although we are starting to find the limits to the high-grade pods in the flat overlying sheet structures, Investigator is moving the Paris prospect to a new level with the recognition of the first of the mineralised feeder structures that we predicted to underlie a large epithermal system like Paris.”

International Goldfields hits new gold in Brazil.

/in /by

THE DRILL SERGEANT: International Goldfields has received assay results from drilling conducted at the Ana Prospect located within the company’s 93 per cent-owned Latin gold project In Brazil.

The company has claimed the results have confirmed the discovery of a promising gold-copper discovery.

Highlights of the drilling results include:

– 21 metres at 5.9 grams per tonne gold from 45 metres, including 8 metres at 13.6 grams per tonne gold;

– 18m at 3.24g/t gold from 33m; and

– 6m at 5.18g/t gold from 36m.

Best copper intercepts include:

– 9m at 0.23 per cent copper from 51m;

– 9m at 0.24 per cent copper from 33m; and
 
– 6m 0.68 per cent copper from 36m.

The company said the assay results of 21m at 5.9g/t gold reinforces the potential for the tenor of the mineralisation at the Ana prospect as it is of teh opinion this combines with previously reported intercepts of 18m at 3.24g/t gold and 6m at 5.18g/t gold to confirm high-grade gold mineralisation along the newly drilled east-west trending vein zone.

“While International Goldfields is very excited about the high grade vein-gold intercepts at Ana, and will continue to target quartz veins to bring forth potential resources, the team is also excited about the results of the surface geochemistry that defines several targets for potential porphyry style mineralisation,” International Goldfields chief executive officer Travis Schwertfeger said in the company’s announcement to teh Australian Securities Exchange.

“Identifying large, bulk-mineable gold-copper targets has been the objective of the company since acquiring the project last year, and the recent work at Ana has defined the project’s best target to date.”

International Goldfields said it would be undertaking detailed mapping of the Ana prospect throughout the month of April as well as integrating datasets with surface geochemistry results to define drill targets.

The company will also have surface geochemistry crews carrying out soil sampling on other regional targets in the coming months.

An agreement is in place for 6,000m of RC drilling at the Latin gold project expected to commence in May.

Corazon discovers new sulphide zone at Lynn Lake

/in /by

THE DRILL SERGEANT: Canada-focused nickel sulphide exploration play Corazon Mining has claimed discovery of a new zone of sulphide mineralisation at the company’s Lynn Lake nickel-copper sulphide project in Canada.

The company said its most recent drill-hole (CRZ017) has defined sulphide mineralisation with approximately 51 metres of disseminated nickel-copper sulphides, including zones of up to four metres of higher-grade semi-massive to massive sulphide.

The drilling interested mineralisation at 670m down-hole.

This is at a shallower level and approximately 50m to the east of the strong sulphide mineralisation which has been the target of Corazon’s drilling at the Lynn Lake project since its discovery in 2011.

CRZ017 is the first drill hole into the eastern margin of the EL Plug, an area that has recently been highlighted as prospective by electromagnetic (EM) geophysics.

“EM is effective in identifying massive sulphide typical of the high-grade mineralisation at Lynn Lake,” Corazon Mining said in its ASX announcement.

“Within these deposits, massive high-grade nickel-copper mineralisation produces a stronger conductive anomaly than lower-grade semi-massive to disseminated mineralisation.”

The company said it was encouraging this particular hole had intersected such a broad zone of mineralisation so close to, what it considers to be, a strong geophysical anomaly.

Corazon described the identified conductor to be significantly stronger than any off-hole conductor it has been able to define so far within the EL Deposit and as such has become a priority target for the company.

“While determining the exact location and dimensions of this conductor will require additional work, modelling suggests that the conductor lies east of and at a similar level to mineralisation defined by Corazon’s drilling and is possibly a parallel feature between 700 metres and 850 metres below surface,” the company said.

Corazon said it intends to continue drilling at the EL Deposit and in the short-term the eastern and south-eastern margin of the intrusion will be a priority focus.

The company aims to define the potential of the EL Deposit at depth and progress the Lynn Lake project towards development.

Black Fire encouraged by Nevada drill results

/in /by

THE DRILL SERGEANT: Black Fire Minerals has received assay results for the final four diamond drill holes completed as part of the Desert Scheelite resource drilling program at the company’s Pilot Mountain tungsten project located in Nevada, USA.

The last two diamond drill holes of the program, DSDD-14 and DSDD-15 both intersected substantial tungsten (scheelite) bearing skarn mineralisation and returned encouraging down-hole assay results including:

–    13.9 metres at 0.89 per cent tungsten, 1.75 per cent copper and 31 grams per tonne silver from 198.7 metres, including 7.2 metres at 1.16 per cent tungsten, 2.15 per cent copper and 37 grams per tonne silver from 202.3 metres; (Hole DSDD-15)

–    20.3m at 0.35 per cent tungsten, 0.22 per cent copper and 6g/t silver from 188.1m, including 1.8m at 1.24 per cent tungsten, 0.20 per cent copper and 8g/t silver from 193.5m.

Other Encouraging results were also returned from the other two holes including:
 
–    12.1m @ 0.42 per cent tungsten and 33g/t silver from 153.9m.

Black Fire said the results achieved in hole DSDD-15 represent the best copper intersection ever recorded at the Desert Scheelite deposit and that it may be indicating a vector towards increasing copper grades.

“The Board is extremely pleased with the results of the final holes from the Desert Scheelite drilling program and are particularly highly-encouraged by the remarkable result of hole DSDD-15 which has successfully extended the Desert Scheelite deposit at least 150 metres to the east outside of the historic Union Carbide Feasibility Study area,” Black Fire Minerals chairman Anthony Baillieu said in the company’s announcement to the Australian Securities Exchange.

“These results have confirmed the company’s belief in the exploration upside potential of the Pilot Mountain project.

“Work has now commenced on the maiden JORC-compliant resource estimate for Desert Scheelite which is on track for delivery in June, and which will lead on to the scoping study to be delivered later in 2012.”

Black Fire said the latest drill intersections have confirmed substantial resource tonnage upside potential having defined significant tungsten skarn mineralisation over 650m of strike and a vertical extent of 330m.

New high-grade copper results strengthens Rex development options

/in /by

THE DRILL SERGEANT: Rex Minerals has continued positive news flow of high-grade copper results from infill and extension drilling underway at the company’s 100 per cent-owned Hillside copper project in South Australia.

The company said the recent results have broadened its mine development options with assay results from the latest drill holes at Hillside demonstrating further extensions to the recently-discovered high-grade zones within the Dart and Zanoni structures.

Rex has an assessment of the development options for Hillside underway, which includes commencing production from a shallow higher-grade open pit mine.

This latest round of results of high‐grade copper intersections stem from drilling conducted at the Hillside project since July 2011 and as such they are not contained within the current Hillside Mineral Resource Estimate, which the company released in July 2011.

Highlights of the latest results from drilling at Hillside include:

32 metres at 1.0 per cent copper, 0.1 grams per tonne gold and 16 per cent iron for 1.2 per cent copper equivalent, including 6 metres at 3.1 per cent copper, 0.5 grams per tonne gold and 22 per cent iron for 3.4 per cent copper equivalent – Dart/Zanoni structure;

22m at 1.0 per cent copper, 0.2g/t gold and 17 per cent iron for 1.2 per cent copper equivalent – Zanoni structure;

30m at 2.0 per cent copper, 0.8g/t gold and 21 per cent iron for 2.5 per cent copper equivalent, including 8m at 5.1 per cent copper, 2.9g/t gold and 22 per cent iron for 6.3 per cent copper equivalent – Dart structure;

11m at 1.5 per cent copper, 0.5g/t gold and 20 per cent iron for 1.9 per cent copper equivalent – Zanoni structure; and

18m at 3.7 per cent copper, 0.3g/t gold and 24 per cent iron for 3.9 per cent copper equivalent, including 4m at 12.9 per cent copper, 0.6g/t gold and 28 per cent iron for 12.7 per cent copper equivalent – Zanoni structure.

“The latest results, when added to the other recent high‐grade intersections on the Dart and Zanoni, have quickly provided Rex with valuable options to be considered as we move towards mine development at Hillside,” Rex Minerals managing director Steve Olsen said in the company’s announcement to the Australian Securities Exchange.

“Having completed the recent capital raising, the discovery of shallow, high‐grade ore has placed Rex in a strong position to maximise the value of the Hillside project.”

Talisman scares up exploration targets at Halloween

/in /by

THE DRILL SERGEANT: A maiden drilling program conducted by Talisman Mining at the company’s Halloween project in Western Australia has quickly delivered a series of encouraging gold intercepts.

Results from the 2,158 metre RC drilling program include:

–    10 metres at 3.56 grams per tonne gold from 84 metres, including 2 metres at 4.9 grams per tonne gold from 84 metres and 2 metres at 10.40 grams per tonne gold from 86 metres;

–    6m at 1.52g/t gold from 18m, including 2m at 3.26g/t gold from 20m;

–    28m at 0.53g/t gold from 70m, including 2m at 1.90g/t gold from 70m and 2m at 3.56g/t gold from 78m; and

–    2m at 1.14g/t gold from 62m.

The drilling program at Halloween was designed to test a series of copper-gold soil geochemical anomalies which Talisman said had been identified through an exploration program of geological mapping and in-fill soil sampling.

“The gold mineralisation identified from the drilling program appears to be related to strong silica-carbonate-epidote-pyrite alteration along a volcanic sedimentary horizon and adjacent basalt with up to 25 per cent disseminated/stringer pyrite and trace chalcopyrite mineralisation,” Talisman Mining said in its ASX announcement.

“The host volcanics intersected in the drill holes also show pervasive magnetite development and strong manganese enrichment with elevated zinc-lead geochemistry.

“These are key pathfinders which are potentially indicative of a VMS-related exhalative mineralising system.”
Talisman said its previous exploration experience in the Doolgunna region has indicated Fixed Loop Electromagnetic (FLEM) surveys over key exploration target areas may provide useful exploration targeting information.

The company is set to commence a detailed FLEM survey over the Halloween prospective volcanic corridor.

The aim of this survey will be to defining follow-up conductive drill targets that might be related to massive copper-gold sulphides along strike and down dip from the better RC gold drill results.

The FLEM survey will be completed in April. Talisman indicated further RC, and potentially diamond drilling, will most likely be undertaken later in the June Quarter.

The Halloween project is situated 16.5 kilometres west of Talisman’s Springfield VMS copper-gold project and 11.5km south-west of the DeGrussa VMS copper-gold project, currently being developed by Sandfire Resources.
 
Talsiman said it has interpreted the mafic volcanics and sediments at Halloween to be part of the Narracoota Volcanic Formation, which hosts the DeGrussa VMS deposits to the east of Halloween.

Adelaide Resources confirms copper / gold discovery at Paskeville

/in /by

THE DRILL SERGEANT: Adelaide Resources has claimed confirmation of a copper / gold discovery at the Paskeville prospect situated within the Moonta project, located on the Yorke Peninsula of South Australia.

Recent drilling undertaken at Paskeville returned an un-bottomed intersection of 42 metres at 1.10 per cent copper and 0.11 grams per tonne gold, including 5 metres at 2.93 per cent copper and 9 metres at 1.69 per cent copper.

The latest results follow an announcement made by Adelaide Resources in March of intersections of 10m at 1.06 per cent copper and 9m at 1.27 per cent copper from the first hole drilled by the company at Paskeville.

Since then Adelaide has completed a further 23 aircore holes and a single diamond drill hole that have returned results including:

–    7m at 1.16 per cent copper and 0.13g/t gold;

–    7m at 1.07 per cent copper;

–    7m at 1.40 per cent copper and 0.26g/t gold; and

–    5m at 1.05 per cent copper.

The drilling also identified the presence of silver with a best intersection of 10m at 26.6g/t silver.

“Compelling targets exist along strike from the area drilled to date, and on the broader Paskeville geochemical anomaly which is much larger than the area drilled so far,” Adelaide Resources said in its ASX announcement.

“In light of these excellent results the company’s Board has approved additional funding to immediately commence follow-up drilling.”

Centaurus has completed a total of 2,900 metres of drilling at Serra da Lontra (1,600m of diamond and 1,300m of RC drilling), out of a planned 7,500m drilling program, which has been designed to support a maiden JORC resource estimate for the project.

“We are very pleased with these early results, which have given us significant confidence in the potential of this Project to underpin our export strategy in Brazil,” Centaurus Metals managing director Darren Gordon said in the company’s announcement to the Australian Securities Exchange.

“Our focus will be to progress the drilling, in parallel with ongoing geotechnical drilling at Jambreiro, as the basis for a maiden JORC resource at Serra da Lontra which we are confident of delivering in July this year.”

Highlights of the first drill results include:

34 metres at 36.6 per cent iron, 8.4 per cent aluminium oxide and 0.05 per cent phosphorous from surface;

15m at 36.6 per cent iron, 2.2 per cent aluminium oxide and 0.06 per cent phosphorous from 7m and 25m at 33.4 per cent iron, 2.4 per cent aluminium oxide and 0.06 per cent phosphorous from 59m;

21m at 33.9 per cent iron, 6.8 per cent aluminium oxide and 0.06 per cent phosphorous from surface and 10m at 34.3 per cent iron, 5.6 per cent aluminium oxide and 0.07 per cent phosphorous from 25m;

25m at 32.0 per cent iron, 2.0 per cent aluminium oxide and 0.07 per cent phosphorous from 61m;

23.2m at 32.5 per cent iron, 1.2 per cent aluminium oxide and 0.08 per cent phosphorous from 11m;

31.7m at 34.2 per cent iron, 4.7 per cent aluminium oxide and 0.06 per cent phosphorous from surface;

27m at 34.3 per cent iron, 3.2 per cent aluminium oxide and 0.08 per cent phosphorous from 28m; and

11.5m at 41.6 per cent iron, 3.2 per cent aluminium oxide and 0.05 per cent phosphorous from surface and 18.8m at 34.0 per cent iron, 1.2 per cent aluminium oxide and 0.08 per cent phosphorous from 19.8m.

Centaurus said the drilling provided strong support for its Exploration Target of 30 to 50 million tonnes grading 30 to 40 per cent iron for the Serra da Lontra project.

As drilling at the Fittipaldi prospect nears completion, the company will be moving one of the contracted diamond rigs to Jambreiro to commence the geotechnical drilling required as part of the Jambreiro Bankable Feasibility Study.

Blackham fires up new drilling program at Matilda

/in /by

THE DRILL SERGEANT: Blackham Resources has re-commenced drilling at the company’s Matilda gold project with a program of approximately 2,000 metres targeting the Matilda Mine area.

The drilling will pay particular attention to shallow oxide mineralisation at the M10 prospect.

The current drilling follows on from the company’s first campaign at Matilda in February, which returned a number of high-grade intercepts from the M10 prospect including:

–    16 metres at 4.50 grams per tonne gold from 34 metres;

–    7m at14.0g/t gold from 74m;

–    8m at 9.98g/t gold from 107m; and

–    6m at 5.11g/t gold from 41m.

Blackham said the February drilling identified a core shoot, which remains open up and down plunge as well as extensive supergene mineralisation that is open in several directions.

“This current program will build on the original program by testing the extensions of mineralisation as well as following up several new mineralised positions on the peripheries of the M10 prospect and nearby M6 pit,” Blackham Resources said in its ASX announcement.

“Results from the program are expected around the end of April.”

In conjunction with the Matilda drilling, Blackham said it is continuing to evaluate resource opportunities at the project following its recent upgrade of the Regent deposit to 237,000 ounces of gold and a combined project total of 757,000 ounces of gold.

Blackham’s exploration work is targeting previously defined deposits, which it said are most likely to be converted to reserves in the near term.

Kumarina increases knowledge at Murrin Murrin project

/in /by

THE DRILL SERGEANT:  Kumarina Resources has received results from a recent drilling campaign undertaken on the Malcolm /Challenger open pits at the company’s 100 per cent-owned Murrin Murrin project in Western Australia.

Highlights from the drilling results include:

–    13 metres at 6.26 grams per tonne gold;

–    2m at 3.46g/t gold;

–    4m at 3.68g/t gold;

–    3m at 3.75g/t gold; and

–    1m at 2.85g/t gold (EOH).

“These results enhance previous results reported in the Prospectus and furthers the company’s understanding of the structure,” Kumarina Resources managing director Jamie Sullivan said in the company’s announcement to the Australian Securities Exchange.

“The results will be used, along with a further phase of drilling, to quantify resources available from expansion of the two pits, which were only mined to a depth of 30 metres.”

Kumarina drilled twenty RC holes for 1410m along the eastern side of the Malcolm and Challenger gold pits.

Step-out holes were designed to test for extensions of gold mineralisation under and between the two pits.

The company said the results provide further support to its earlier drilling campaigns in that it has demonstrated the mineralisation below the pit floor is continuous down to at least 55 metres.

The mineralisation remains open at depth.

Kumarina said it is planning further infill and deeper drilling to test continuity of mineralisation between sections and down dip.
