THE DRILL SERGEANT: Hillgrove Resources (ASX: HGO) has reported encouraging hits from one of the first exploration drill holes to be drilled on a Mining Lease, 200 metres to the north of the current resource profile at the company’s Kanmantoo copper mine, located in the Adelaide Hills.

The 433 metre deep reverse circulation (RC) hole returned the following assays at a depth of 300 metres below surface:

28 metres at 0.61 per cent copper, 0.14 grams per tonne gold and 2.6g/t silver at a 0.2 per cent copper cut off – within a broader mineralised zone of:

39m at 0.47 per cent copper, 0.11g/t gold and 2.1g/t silver at a 0.1 per cent copper cut off, from 324m downhole.

Hillgrove reported the 28 metre intersection included:

A higher grade zone of 10 metres at 0.88 per cent copper, 0.18g/t gold and 3.2g/t silver; and

A peak one metre interval of 2.86 per cent copper, 0.8g/t gold and 9.4g/t silver.

The company explained the intersected mineralisation is down dip of existing shallow level mineralisation to the north of the main ore zones and Giant pit, in an area where no previous deep drilling has taken place.

Hillgrove has interpreted the location and tenor of the mineralised intersection to indicate:

It is within the same geological domain and along strike of the main ore zones in the Giant pit, approximately 200m north of the edge of the current mineralisation at the same depth;

The intersection location is coincident with a density target Hillgrove identified during detailed gravity surveys undertaken in late 2014, which it has previously announced to the market; and

Mineralised intersection copper and gold grades are similar to current mining areas within the Kavanagh/Giant pits, with similar copper/gold ratio.

“This is the first stage of a targeted program aimed at extending the life of the Kanmantoo mine, and was designed to test a pronounced coincident gravity, magnetic and electromagnetic (EM) target,” Hillgrove Resources said in its ASX announcement.

“Next steps for this area north of the Giant pit will include a downhole EM survey, a plan for six follow up holes along strike and based on downhole EM further up-dip drilling will be planned.”

THE DRILL SERGEANT: Centrex Metals (ASX: CXM) has completed a four hole diamond drilling program at the company’s Goulburn polymetallic project in New South Wales.

The drill program targeted extensions of the known Collector Skarn deposit plus a coincident magnetic and IP anomaly to the northeast.

Centrex has already released results of the first hole of the program CD010, which intersected a zone of massive and semi-massive polymetallic sulphide mineralisation at the newly discovered Collector North Polymetallic prospect.

The company has just taken receipt of assay results of the second hole of the program CD009, which targeted mineralisation at Collector down-dip and along strike from historic holes DDH C3 and DDH C2.

CD009 intersected a zone of massive and semi massive sulphides with:

8 metres at 2.5 per cent zinc, 0.8 per cent copper, 0.4 per cent lead and 10.6 grams per tonne silver from 242.2m, including 3m at 4.5 per cent zinc, 0.9 per cent copper, 1 per cent lead and 17.8g/t silver from 242.2m.

“Whilst the results of CD009 were encouraging and showed an extension of the skarn mineralisation from the historic holes, a down-hole gyroscopic survey showed CD009 deviated significantly north of its planned orientation causing it to intersect the targeted magnetic anomaly deeper than planned,” Centrex Metals said in its ASX announcement.

THE DRILL SERGEANT: Windward Resources (ASX: WIN) has commenced drilling at the Western Margin prospect (WMA1 conductor), located within the company’s Fraser Range North project in Western Australia.

The Fraser North project is located just on the doorstep of the Nova deposit of Fraser Range trendsetter Sirius Resources (ASX: SIR).

Windward has modelled the WMA1 conductor as a 1.6 kilometre by 600 metre north-west dipping body.

It has interpreted the top of the conductor to lie at a depth of approximately 250m, which it intends drill testing at approximately 325m below surface.

Windward claims the WMA1 conductor has the highest conductivity of any conductor it has been able to identify to date (7400 siemens) and a time constant of 185 milliseconds.

The company explained the combination of this high conductivity and time constant are typical for massive sulphides.

The conductor has been modelled to sit between two north-west striking faults, which Windward has interpreted to run through or very close to the nearby Nova deposit.

“Based on the information we have to date we believe WMA1 is highly promising and look forward to the results of the drilling within the next fortnight,” Windward Resources managing director David Frances said in the company’s announcement to the Australian Securities Exchange.

THE DRILL SERGEANT: Metals of Africa (ASX: MTA) has confirmed high-grade lead and zinc mineralisation from an ongoing exploration program at the company’s Kroussou project in Gabon.

The company has encountered grades of up to 9.69 per cent zinc and 33.1 per cent lead with elevated copper and silver hits from the first batch of rock samples taken from a rock chip sampling program of surface outcrop at the project.

MTA claims the results to be the highest known lead and zinc grades ever reported in Gabon.

The company reported the discovery of additional outcropping zinc and lead prospects, over
50 kilometres, and expects laboratory assay results from this work to be available in May 2015.

MTA considers the laboratory results to have confirmed the Kroussou project to be a highly-prospective lead‐zinc mineralised system.

The company explained the rocks were sourced from outcrops at the Kroussou and Dikaki prospects, which outcrop for 3km and 1km respectively with flat lying mineralised beds ranging in thickness and outcrops up to five metres thick.

Metals of Africa indicated it has now completed a detailed mapping program at the Kroussou project.
“The company’s works program remains on schedule and it is currently compiling field results from this work, which will include another batch of outcropping rock samples for laboratory analysis,” the company said in its ASX announcement.

“The mapping program has targeted identification of the Cretaceous geological contact over the 85 kilometre length of the Kroussou license.

“It aimed at identifying additional prospective lead‐ zinc mineralised prospects within the project area, and to provide an indication of lead‐zinc grades where outcropping for historically defined prospects.

“Additional mineralisation prospects have been confirmed over a distance spanning more than 50 kilometres, along strike of the Dikaki prospect, and will be reported on in due course.”

THE DRILL SERGEANT: Impact Minerals (ASX: IPT) has identified six targets for follow up drilling at the Red Hill prospect within the company’s Broken Hill Joint Venture project in New South Wales.

Impact recently announced a discovery of high-grade copper-nickel-platinum group metal (PGM) mineralisation at Red Hill.

The six targets – cleverly named T1 to T6 – were identified during Impact’s exploration activity carried out over the past six months.

The drilling program is expected to be completed by the end of May.

Target T1: follow up drilling at the Red Hill mine

At T1 Impact has claimed discovery of a 25 to 30 metre thick near-surface zone of mineralisation beneath the dormant Red Hill mine containing high-grade PGM’s together with nickel and copper associated with an ultramafic intrusion.

Target T2: ground electromagnetic (EM) anomaly; possible massive sulphide

Target T2 is an EM anomaly that was identified in a ground geophysical surve. It has been modelled to be at depth of about 100m below surface.

Target T3: down hole electromagnetic (EM target); possible massive sulphide

Target T3 is a small EM anomaly identified via a down-hole EM survey Impact conducted on drill hole RDH003. It lies vertically beneath the Simons Find prospect which returned rock chip samples of up to 1.1 per cent nickel, 1.9 per cent copper, 1.9 grams per tonne gold, 54g/t silver and 1.7g/t palladium.

Targets T4: rock chip geochemistry target

Impact explained the eastern side of the Red Hill intrusion is characterised by elevated copper-gold-platinum-palladium-in-soil and rock chip samples. Target T4 will be a test of the eastern contact of the intrusion with the surrounding rocks.

Target T5: Induced Polarisation anomaly

An IP anomaly has been identified at a depth of about 100m below surface in the centre of the Red Hill intrusion. The company has determined this anomaly may be caused by disseminated sulphide and/or magnetite towards the base of or below the intrusion.

Target T6: magnetic anomaly

Airborne magnetic data indicates the Red Hill intrusion extends for about 100m to the north of the last outcrop beneath a recent stream bed. This area lies at the projected intersection between the Lode Rocks of Target T2 and the intrusion and is thus similar to the location of the Red Hill mine, which is also associated with Lode Rocks close to the western edge of the intrusion.
