The project has a current JORC Inferred Resource of 241.6 million tonnes at 54.3 per cent iron, which includes a main CID zone of 169.1 million tonnes at 55.6 per cent iron, and an Exploration Target of 350 to 400 million tonnes at 54 to 56 per cent iron.

According to Winmar the Resource at the Hamersley project remains open in most directions, with the current drill program intersecting mineralisation in the southwest and northeastern areas.

The company indicated it anticipates conducting follow up infill drilling on completion of the current program as it is required.

“CID mineralisation has been logged in new drill holes up to 800 metres in distance from the current resource, which is extremely encouraging,” Winmar Resources said in its ASX announcement.

“Samples have been submitted for analysis and assay results from the drill program are expected to be received during July.

“The current phase of drilling is designed to deliver a significant Resource upgrade.

“The new Resource statement will be used to provide an updated scoping study and as input for potential mining plans.”

Part of this phase of drilling will entail Winmar conducting a 600 metre diamond drill program to provide bulk material for metallurgical testing.

This is scheduled to commence by end-June, and the company said results will be released as they become available.

Winmar has a Joint Venture Agreement with Cazaly Iron, a wholly owned subsidiary of Cazaly Resources, for the Hamersley project, whereby Winmar is able to earn 51 per cent of the project by way of exploration expenditure.

Under the joint venture Winmar is undertaking and managing a $2.2 million exploration and development program in 2012 at the Hamersley project.

The Hamersley project is located in close proximity to Fortescue Metals’ Solomon project and Rio Tinto’s Marandoo and Brockman mines.

TNG Limited expands Mount Peake

/in /by

THE DRILL SERGEANT: Australian resources company TNG Limited has completed a regional drilling program at the company’s Mount Peake iron-vanadium-titanium project in the Northern Territory.

TNG said the drilling has confirmed the potential to further increase its resource inventory in the region.

The company had previously identified three large magnetic zones and one isolated magnetic anomaly from geophysics and fieldwork to have the potential to be new vanadium- and titanium-bearing magnetite zones.

According to the company the drilling has confirmed two of these magnetic zones as large magnetite-rich gabbro bodies while one drill hole intersected a large granitic body in the southern anomaly.

Drilling results included:

–    24 metres at 23.36 per cent iron, 0.20 per cent vanadium oxide and 3 per cent titanium oxide and 4 metres at 23.82 per cent iron, 0.17 per cent vanadium oxide and 3.16 titanium oxide;

–    34m at 21.94 per cent iron, 0.20 per cent vanadium oxide and 4.63 titanium oxide, including 7m at 0.25 per cent vanadium oxide and 5.36 per cent titanium oxide and 5m at 0.30 per cent vanadium oxide and 4.60 per cent titanium oxide.

“Assay results from these holes have produced grades consistent with those noted at the Mount Peake deposit and provide further encouragement that higher mineralised grades may exist within the magnetic features,” TNG Limited said in its ASX announcement.

“Further drilling will be required to substantiate this but as mineralisation has been identified in this preliminary phase the potential is encouraging.

“It also provides encouragement to further assess untested magnetic features in the MPPA.”

The company has concluded these results open up the potential in the MMPA for an increase to the current Mount Peake JORC Indicated and Inferred Resource of 160 million tonnes at 0.3 per cent vanadium oxide, 5 per cent titanium oxide and 23 per cent iron:

–    Indicated 110Mt at 0.29 per cent vanadium oxide, 5.3 per cent titanium oxide and 23 per cent iron;

–    Inferred 48Mt at 0.24 per cent vanadium oxide, 4.5 per cent titanium oxide and 21 per cent iron).

TNG Limited has an exploration target for the MPPA of 500 to 700 million tonnes with a grade range of 0.2 to 0.4 per cent vanadium oxide, 20 to 40 per cent iron, 4 to 6 per cent titanium oxide.

AMMG produces encouraging results at Bencubbin

/in /by

THE DRILL SERGEANT: The first phase of reverse circulation (RC) drilling being conducted by Australia Minerals and Mining Group at the company’s 100 per cent-owned Annie’s Prospect at the Bencubbin iron ore project in Western Australia has produced encouraging Davis Tube Recovery (DTR) results.

The results were achieved from what the company described as “the most promising iron mineralisation zones”, with an average concentrate grade of above 70 per cent iron, an average mass recovery of 42.8 per cent and low contaminants.

“This first stage drilling program has produced extremely promising iron concentrate results from the beneficiation DTRs”, Australia Minerals and Mining Group managing director Ric Dawson said in the company’s announcement to the Australian Securities Exchange.

“With a coarser grind size than has previously been reported in the Mid-West area, this has the benefit of lower energy input in a processing plant.

“With potential access to rail infrastructure traversing through the tenement, and the relatively close location to the port of Kwinana, it provides encouragement for pursuing a magnetite project in this locality.”

BrightStar claims new gold discovery

/in /by

THE DRILL SERGEANT: BrightStar Resources has claimed discovery of a new zone of high-grade gold mineralisation during Stage 2 Reverse Circulation (RC) drilling at the company’s Miyabi gold project.

The newly- revealed Dalafuma prospect lies near the southern margin of the Miyabi Structural Corridor (MSC), which hosts the gold deposits BrightSatr has previously defined at Miyabi.

Assay results have been received for the first six holes at Dalafuma and include:

–    6 metres at 4.1 grams per tonne gold from 75 metres;
 
–    18m at 18.3g/t gold from 45m, including 6m at 39.8g/t gold from 48m;

–    6m at 2.7g/t gold from 12m; and

–    9m at 2.9g/t gold from 15m;

The drilling was following up targets generated from RAB and RC drilling carried out by BrightStar throughout 2011 at Miyabi.

The new discovery was initially identified by a high-grade intersection of 21m at 6.7g/t gold from 21m, which was drilled during this program.

“These outstanding results confirm that the Dalafuma prospect has the potential to host a substantial, high grade gold deposit,” BrightStar Resources technical director Paul Payne said in the company’s announcement to the Australian Securities Exchange.

“The high grade zone is open along strike and down dip and we have planned follow-up drilling to commence immediately.”

BrighStar said these initial results from Dalafuma suggest the prospect has potential to host a new high-grade gold deposit additional to the 520,000 ounces the company has already reported at the project.

Havilah hits new copper at Kalkaroo

/in /by

THE DRILL SERGEANT: Havilah Resources has received assay results for the upper part of a diamond drillhole the company reported in May to have visible copper mineralisation.

The assay results include:

–    13 metres at 0.99 per cent copper and 1.05 grams per tonne of gold from 198 metres downhole.

According to the company this intersection is from a previously unknown structure above the usual Kalkaroo prospective sequence.

“The mineralisation appears to be hosted in a low angle, conformable fracture as a vein-filling with the tenor of the mineralisation about twice that of normal Kalkaroo grades,” Havilah said in its ASX announcement.

 The company has also received assays from what it has identified to be a prospective sequence interval in another drill hole that it said confirms an extension of the ore zone down dip from the known resource.

This included an intersection of:

–    33m at 0.37 per cent copper and 0.27g/t gold from 365m downhole.

In common with adjacent drillholes it also includes a molybdenum bearing zone containing:

–    8m at 533 parts per million molybdenum from 376m downhole.

“Core logging, cutting and assaying is still underway on remaining drillholes,” Havilah said.

“Upon compilation and thorough evaluation of all data for the Kalkaroo deep drilling program, consideration will be given to further follow up drilling of the newly identified mineralisation…, given its proximity to the current open pit.”

Alchemy Resources awarded WA government drill incentive

/in /by

THE DRILL SERGEANT: Alchemy Resources has been awarded a $120,000 grant through the Western Australian Governments’ Exploration Incentive Scheme.

Alchemy said the grant would support a targeted drilling program to be undertaken at the company’s Bryah Basin copper project in WA.

The Bryah Basin copper project covers over 45 kilometres of strike length of volcanic and sedimentary rocks of the Narracoota volcanic sequence and is situated to the west of Sandfire Resources’ DeGrussa copper-gold deposit.

“The grant will be used to investigate untested VTEM anomalies within the prospective Narracoota volcanic sequence and Peak Hill Schist on tenements recently acquired from Grosvenor Gold,” Alchemy Resources said in iits ASX announcement.

Alchemy identified the drill targets during it ongoing review of Grosvenor’s exploration and geological database.

The targets were delineated from interpretation of versatile time electromagnetic (VTEM) and preliminary moving loop electromagnetic (MLEM) surveys.

The company said it expects the drilling program to commence in the September quarter, once all necessary permits have been obtained.

“Award of the competitive grant validates Alchemy’s innovative and systematic approach to conducting its exploration at the Bryah Basin copper project,” the company said.

“Exploration of Alchemy’s Bryah Basin landholding is continuing with geological mapping and geochemical sampling on the recently acquired tenements currently underway, and with ground geophysical surveys planned to commence next month.

“In combination, the results from these surveys will be used to define additional targets for drill testing in the second half of 2012.”

Mary Kathleen JV hits strong REE

The Elaine 2 and Elaine 3 prospects are situated approximately one kilometre southeast of the Elaine 1 prospect, which consists of Elaine (uranium-REE) and Elaine North (copper-cobalt-gold) and is currently subject to resource estimation.

Elaine 2 and 3 are also situated along strike of the regional Mary K shear.

According to the JV these areas were historically explored for uranium.

A five diamond hole scout drill program was carried out focussing on the evaluation of copper, rare earth and thorium potential targeting areas of historic drilling, ground scintillometer/radiometric and soil geochemistry anomalies.

The JV has received assay results for the first 3 drill holes with highlights including:

Elaine 2 prospect

–    19 metres at 2,050 parts per million Total Rare Earth Oxides (TREO), 0.17 kilograms per tonne thorium oxide and 0.04 kilograms per tonne uranium from 55 metres; and

–    34m at 2,135ppm TREO, 0.18kg/t thorium oxide and 0.03kg/t uranium from 8m.

Elaine 3 prospect

–    22m at 1,633ppm TREO, 0.22kg/t thorium oxide and 0.03kg/t uranium from 71m.

“These initial results are exciting in that these areas have not previously been tested for rare earth mineralisation,” Chinalco Yunnan Copper Resources managing director Jason Beckton said in the company’s announcement to the Australian Securities Exchange.

“The total rare earth mineralisation at the Elaine U-REE deposit, one kilometre to the northeast is characterised by greater than 95 per cent light rare earth elements of cerium, lanthanum and neodymium.

“What we are seeing at Elaine 2 is the heavy rare earth component, dominated by dysprosium, gadolinium, erbium and terbium is now ranging 20 per cent to 35 per cent of the total rare earth mineralisation.

“Added to this the significant and broad intersections of thorium mineralisation and the area is developing into a well-endowed region”.

The JV is currently conducting follow up field work of detailed geological mapping, geochemical and geophysical surveys to assist in defining the next phase of drilling.

Kentor hits high-grade gold at Jervois

/in /by

THE DRILL SERGEANT: Kentor Gold has reported a raft of high-grade, near surface drill results from a drilling program at the company’s Jervois copper-silver-gold project in the Northern Territory.

The results returned assays of up to 19.4 per cent copper, 37.6 per cent lead, 14.2 per cent zinc and 702 grams per tonne silver.

Drilling results included:

–    60 metres at 1.73 per cent copper, 3.81 per cent lead, 1.15 per cent zinc, 113.3g/t silver, 0.21g/t gold from 7.1 metres, including 12.06 per cent copper, 2.42 per cent lead, 2.4 per cent zinc, 217.3 g/t silver and 0.62g/t gold in the first 3.35 metres.

–    16.3m at 1.87 per cent copper, 55.3g/t silver and 0.59g/t gold from 15.2m; and

–    10.3m at 2.1 per cent copper and 13.3g/t silver from 17.4 m.

The drilling is part of a feasibility study Kentor is undertaking to follow up a recently completed scoping study, which found Jervois would be a robust project capable of producing strong financial returns.

“These significant, near-surface results continue to confirm the open pit mining potential of the Jervois project,” Kentor Gold managing director Simon Milroy said in the company’s announcement to the Australian Securities Exchange.

“The high grade multi-metal results include good gold grades, strengthening the expectation that we will be able to include gold for the first time in an increased Mineral Resource.”

Kentor indicated the metallurgical drilling it is undertaking at the Jervois project continues to indicate significant mineralisation in targeted areas.

Of the planned 5,459m of diamond drilling, Kentor has now completed 4,179m.

The remaining six diamond tails totalling 1,280m are anticipated to be completed by mid-July.

The company is also nearing completion of a 10,000m RC drilling program with the remaining 11 holes to be drilled this month.

All thirteen metallurgical diamond holes have been delivered to a Perth laboratory where comminution test work and analysis has commenced.

The company said this would build on results it had received from three holes analysed in its earlier test work programs.

Liontown Resources finds new gold zone

/in /by

THE DRILL SERGEANT: Liontown Resources has unearthed a new zone of mineralisation at the Masabi Hill prospect via an ongoing program of drilling being conducted on the company’s Jubilee Reef gold project in Northern Tanzania.

The results come from reverse circulation percussion (RC) drilling being carried out 250m south of the previously discovered mineralised zone at Masabi Hill.

The company said the latest results had provided it further evidence of the project’s potential.

The latest assays returned:

–    20 metres at 2.5 grams per tonne gold from 12 metres and 32 metres grading 2.3 grams per tonne gold from 48 metres within an overall intercept of 80 metres grading 1.7 grams per tonne gold from 8 metres down-hole.

“This new intersection is from the first RC hole drilled into the southern contact of the Masabi Hill granitoid where anomalous gold was defined by shallow RAB/Aircore drilling in 2011,” Liontown Resources explained in its ASX announcement.

“The contact zone is completely covered by transported sediments and has only been partially defined by drilling.

“The newly discovered mineralised contact zone between granitoid and dolerite remains open along strike and at depth.”

The newly-identified zone is located approximately 250m south of a previously discovered central zone of gold mineralisation where drilling by Liontown recently intersected:

–    62m at 2.4g/t gold from 70m including 21m at 4.7g/t gold from 70m.

Liontown commenced a combined RC/aircore/diamond core drilling program at Jubilee Reef at the beginning of May 2012.
