Impact Minerals Adds Further Targets to Commonwealth Drill Program

/in /by

THE DRILL SERGEANT: Impact Minerals (ASX: IPT) described newly-identified drill targets at company’s 100 per cent-owned Commonwealth project, located north of Orange in New South Wales as “compelling”.

Impact Minerals said new drill targets have been identified along the eastern, upper contact of the Silica Hill Rhyolite.

The company explained that, until now, its exploration has been mostly focussed at the Main Shaft-Commonwealth SouthSilica Hill prospects up to one kilometre away on the lower, western contact of the Silica Hill Rhyolite and the underlying thinner Commonwealth Rhyolite.

Here, Impact has discovered high-grade gold-silver-base metal mineralisation it has interpreted to be part of a so-called ‘gold-rich Volcanogenic Massive Sulphide (VMS) system’ with strong similarities to the Eskay Creek deposit in Canada.

“However, certain features within these rhyolites and the associated mineralisation suggest that the area explored to date could be part of a much larger and very prospective high grade ‘feeder zone’ that extends for one kilometre north east through the Silica Hill Rhyolite up to its eastern upper contact with overlying volcanic rocks,” Impact Minerals said in its ASX announcement.

“In addition, the position where the interpreted feeder zone intersects the upper contact is an excellent conceptual target for further gold-rich VMS mineralisation and…geophysical and soil geochemical anomalies support this interpretation and have provided specific drill targets close to or at this location.”

Impact said that detailed research and development completed over the past few years, supports the feeder zone model and these concepts will be further tested in the upcoming drill program.

Impact has identified many follow up drill targets in and around the general Commonwealth-Silica Hill area.

The company said a large drill program to test these new anomalies and also at Welcome Jack will commence on the completion of a Share Purchase Plan, which is currently underway.

Musgrave Minerals Hits Shallow Gold at Lena

/in /by

THE DRILL SERGEANT: Musgrave Minerals (ASX: MGV) reported further high-grade gold results from a recently completed reverse circulation (RC) drilling program at the Break of Day and Lena gold prospects on the Cue project in the Murchison region of Western Australia.

Musgrave Minerals said it had encountered shallow intersections of high-grade gold at Lena that highlight the open-cut potential of the deposit with results including

17MORC073
2 metres at 12.4 grams per tonne gold from 3 metres down hole; and

17MORC079
13m at 9.7g/t gold from 61m down hole, including 1m at 83g/t gold from 62m down hole.

Highlights from infill drilling at Break of Day include:

17MORC055
2m at 10.3g/t gold from 224m down hole.

“Drilling at Lena and Break of Day continues to return strong high grade gold results,” Musgrave Minerals managing director Rob Waugh said in the company’s announcement to the Australian Securities Exchange.

“The near surface high-grade intersections at Lena highlight the open-cut potential of the deposit.

“The high-grade intersection in 17MORC079 is open to the north and at depth demonstrating an opportunity to continue to grow the Lena resource with further drilling.”

Musgrave Minerals said phase two of the drill program at Break of Day and Lena was completed in late May with 35 new drill holes and three hole extensions completed for a total of 6,644m.

The company has been encouraged by the strong gold results it believes will support a new Resource estimate scheduled to be completed in July 2017.

St George Mining Updates Drilling at East Laverton

/in /by

THE DRILL SERGEANT: St George Mining (ASX: SGQ) provided a progress report on drilling being undertaken at the company’s 100 per cent-owned East Laverton project in Western Australia.

St George Mining said Dimond drill hole WINDD005, at the Windsor nickel sulphide target, has been completed to a downhole depth of 150 metres.

The company explained the hole was drilled to test a highly-conductive DHEM plate with high conductivity of 210,000 siemens modelled at 95m downhole.

WINDD005 intersected a thick ultramafic unit from 61m to 142m downhole, however St George said there appeared to be no material in the drill core that could explain the highly conductive EM target.

A DHEM survey completed in WINDD005 recorded two strong off‐hole EM responses– one at 62m downhole and the other at 100m downhole.

St George has had two DHEM plates modelled for follow‐up testing, and drilling of these targets has commenced.

“The DHEM survey data at Windsor suggests that there are a number of conductive sources in the target area and this adds complexity to the modelling of EM plates,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.

“Our exploration model still strongly favours the presence of massive nickel sulphide mineralisation at Windsor and we are pleased the new EM targets provide immediate follow‐up drilling.”

Impact Minerals Identifies New Gold Trends

/in /by

THE DRILL SERGEANT: Impact Minerals (ASX: IPT) has identified two new five-kilometre-long trends within the company’s 100 per cent-owned Commonwealth project north of Orange in New South Wales.

Impact Minerals considers the trends to be prospective for further discoveries of high-grade gold-silver-base metal mineralisation similar to that discovered at Commonwealth-Silica Hill.

“The prospective trends have been recognised as significant following the identification in new drill assay data of extensive barium as an important pathfinder and indicator element directly associated with the Commonwealth-Silica Hill mineralisation,” Impact Minerals said in its ASX announcement.

“This has led to a new interpretation of the barium results from both Impact’s soil geochemistry database and also the Geological Survey of New South Wales regional stream sediment geochemistry database.”

Impact Minerals explained the importance of the presence of barium due to it being an accessory element that can be used as a vector to, and direct indicator of, ore in gold-rich VMS (volcanogenic massive sulphide) deposits such as Eskay Creek in Canada.

Impact believes the work it has completed at Commonwealth-Silica Hill has demonstrated similarities to the Canadian mineralisation.

Drilling completed by Impact in 2016 returned a high-grade seven-metre-thick intercept of massive sulphide.

Recent petrographic work on the intercept identified barite as a component of the mineralisation and accordingly Impact re-submitted the samplessubmitted for assay.

“Barium mostly occurs as barite (barium sulphate) which is very resistive and which requires an (expensive) XRF fusion assay to accurately determine the quantity present,” Impact explained.

“There is a strong correlation between high-grade gold and high-grade barium.

“Sporadic assays from drill holes completed by previous explorers also indicate high-grade barium in places and it is clearly present throughout the massive sulphide mineralisation.

“It is also a minor component in the surrounding disseminated mineralisation and also within the high-grade gold-silver mineralisation at Silica Hill.

“The recognition of extensive barite intimately associated with ore is a further compelling similarity between Commonwealth-Silica Hill and Eskay Creek as well as the nature of the host rock, the style of mineralisation, the contained commodity and pathfinder metals and the high grades of individual units and veins of commodity metals.”

Rox Resources Claims New Fisher East Nickel Mineralisation Discovery

/in /by

THE DRILL SERGEANT: Rox Resources (ASX: RXL) reported “encouraging results” from a recently-completed RC drilling program at the company’s Fisher East project in Western Australia.

Rox Resources said the program had generated the first ever intersection of massive and disseminated nickel sulphides at the Mt Tate prospect, expanding the prospectivity of the Fisher East Ultramafic Belt.

“This new discovery at Mt Tate supports our confidence that Fisher East is an extremely fertile Ultrmafic Belt,” Rox Resources managing director Ian Mulholland said in the company’s announcement to the Australian Securities Exchange.

“Mt Tate is now the fifth nickel sulphide mineralised zone we have identified after Camelwood, Musket, Cannonball and Sabre.

“In addition, the indications of nickel sulphides at Cutlass and Sabre North are also encouraging and worthy of follow-up.

“Our Mineral Resources at Fisher East are 2.04 million tonnes at 2.5 per cent nickel (at a 1.5% Ni cut-off) for 50,600 tonnes of contained nickel, and we are confident of adding to these resources as we continue to test new targets and drill deeper holes at known deposits.”

Highlights of the Mt Tate drilling include:

MFEC127
1 metre at 0.88 per cent nickel from 121m, within semi-massive sulphides. 

MFEC128
2m at 1.45 per cent nickel from 94m, transitional disseminated nickel sulphide.

MFEC135
4m at 0.57 per cent nickel from 141m, disseminated sulphides.

MFEC136
2m at 1.42 per cent nickel from 146m, disseminated sulphides.

MFEC137
1m at 0.81 per cent nickel from 196m, disseminated sulphides.

MFEC140
1m at 0.85 per cent nickel from 125m, within massive sulphide.


At Cutlass:

MFEC132
4m at 0.43 per cent nickel Ni from 108m, and 4m at 0.35 per cent nickel from 134m, two zones of low grade disseminated nickel sulphides.

At Sabre North:

MFEC133
5m at 0.67 per cent nickel from 115m, disseminated sulphides.

Rox Resources said a seven-metre-thick massive pyrite zone at Mt Tate sits approximately 20m stratigraphically above (downhole because sequence is over-turned) the nickel sulphide zone.

This massive pyrite zone was also intersected at Tomahawk, which the company considers to be of importance interpreting it to show a strong sulphide source is present, which is an essential ingredient to the formation of nickel sulphides.

Rox intends further investigation of the mineralisation at Mt Tate with downhole EM before deeper drilling is contemplated.

Diamond drilling is currently underway at Fisher East to test downhole EM anomalies at Camelwood, Musket, and Sabre.

Impact Minerals Approved for Commonwealth Drill Program

/in /by

THE DRILL SERGEANT: Impact Minerals (ASX: IPT) has received all statutory environmental approvals for a follow up drill program to be conducted at the company’s 100 per cent-owned Commonwealth project, north of Orange in New South Wales.

Impact Minerals said clearing of access tracks and drill pads will commence this week with drilling scheduled to commence on completion of a current Share Purchase Plan.

“The drill program will test a significant number of targets along trend and at depth from the high-grade mineralisation discovered in the Commonwealth-Silica Hill area as well as new targets in the immediate surrounding areas,” Impact Minerals explained in its ASX announcement.

The Commonwealth project forms part of Impact’s 100 per cent-owned land holding of 1,000 square kilometres in the Lachlan Foldbelt, home to numerous gold and copper mines including the giant Cadia deposit near Orange.

Impact has intersected silver mineralisation at Silica Hill in previous drilling of six drill holes across and of 200 metres by 100m down to a depth of 120m below surface and with an average true thickness of at least between 50m and 70m.

The mineralisation Impact has previously encountered is open in all directions including up dip with four drill holes out of the six having returned gram-times-metre intercepts of more than 100 gram.metres.

Impact considers these to be robust results for potential bulk mining, saying they indicate the potential to increase the resources at the Commonwealth project, which currently stand at 720,000 tonnes at 2.8 grams per tonne gold, 48g/t silver, 1.5 per cent zinc and 0.6 per cent lead.

Alliance Resources Commences Wilcherry HEM Survey

/in /by

THE DRILL SERGEANT: Alliance Resources (ASX: AGS) has commenced ground moving loop electromagnetic (MLEM) surveys to follow up heli-electromagnetic (HEM) conductors at the company’s Wilcherry project in South Australia.

The Wilcherry project is a Joint Venture between Alliance (51%) and Tyranna Resources (ASX: TYX) (49%).

Alliance Resources said the high powered MLEM survey program, being undertaken by Gap Geophysics Australia, kicked off at the first of four targets to follow-up first order regional HEM survey conductors identified during a survey completed in December 2016.

The company said the targets may be prospective for accumulations of massive sulphides.

A total of 22 traverse lines are planned for 34 line km of surveying (353 stations).

The aims of the survey are:

To follow-up HEM anomalism and confirm the presence of bedrock conductors at the target areas; and

To optimise drill targets in order to test bedrock conductors for economic concentrations of metals.

“Preliminary interpretation by Southern Geoscience Consultants has identified four first order targets (in addition to Zealous and Telephone Dam), based on how discrete the anomalies appear, strength of the HEM signatures, and clear association or correlation with structure observed in aeromagnetic data,” Alliance Resources said in its ASX announcement.

“It should be noted that the HEM survey data is collected at 25Hz base frequency and as such, anomalies defined at late channels can range between weak bedrock conductors to strong bedrock conductors.

“The strength of the conductors can only be resolved with ground EM follow‐ up.”

Vimy Resources Updates Mulga Rock Mineral Resource

/in /by

THE DRILL SERGEANT: Vimy Resources (ASX: VMY) announced a Mineral Resource update on the Ambassador deposit at the company’s Mulga Rock project (MRP) in Western Australia.

Vimy Resources explained the update relates to the Ambassador East deposit where drilling was completed in 2016, and is part of a larger resource update of the entire Mulga Rock Project which is due for release in June 2016.

Highlights from the Mineral Resource Estimation (MRE) update are:

A maiden Measured Mineral Resource for the MRP of 12.4 million pounds uranium, including a high-grade, Measured Resource at greater than 0.11 per cent uranium (1,100ppm);

A 14 per cent increase in contained metal at Ambassador East (from 12.4 to 14.1 million pounds uranium);

Further resource work underway indicates a 20 to 25 per cent uplift in metal in the entire Ambassador Resource; and

Drilling results that include intersections of: 7.5 metres at 2,598ppm uranium and 4.5m at 2,792ppm uranium.

Two open pits were excavated as part of an ongoing Definitive Feasibility Study (DFS) on the Ambassador deposit, from which 75 dry tonnes of ore was excavated.

A subsequent assessment of the material from the test pits confirmed the contained U3O8 in the excavated material was 53 per cent higher than expected from the resource model. 

This provided Vimy with the impetus to conduct further ‘Optimisation Drilling’, in 2016, the results from which have been included in the recent update.

The 2016 drilling program was carried out over part of the Ambassador East deposit which falls inside the current pit designs.

Key intersections include:

NNA7060 (AC)
5m at 2,090ppm uranium from 38.5m;

NNA7092 (AC)
4.5m at 2,792ppm uranium from 39.5m;

NND7108 (DD)
2.3m at 3,008ppm uranium from 44.9m;

NND7304 (DD)
4.9m at 2,417ppm uranium from 44.9m;

NNA7146 (AC)
7.5m at 2,598ppm uranium from 43.5m; and

NND7041 (DD)
2.3m at 4,059ppm uranium from 34.5m.

Vimy said Ambassador East will provide ROM Feed for the first years of production, noting a 92 per cent conversion from Indicated to Measured Status. 

“This resource upgrade is very positive for us, but more importantly, the lessons we’ve learned and applied to our models will result in very improved economics in the DFS,” Vimy Resources managing director Mike Young said in the company’s announcement to the Australian Securities Exchange.

“Instead of talking about forward demand for uranium, we’ll be able to compete in today’s market.

“In a nutshell, these results have changed our paradigm from a wannabe to a gonna-be.”

Impact Minerals Identifies New Priority Drill Targets

/in /by

THE DRILL SERGEANT: Impact Minerals (ASX: IPT) has identified specific drill targets it believes to have potential to extend high-grade gold-silver-zinc-lead-copper massive sulphide mineralisation that forms part of the Commonwealth deposit at the company’s 100 per cent-owned Commonwealth project north of Orange in New South Wales.

Impact Minerals said the targets occur at depth below and along trend from Main Shaft, which lies at the northern end of the Commonwealth deposit in a new area called the Main Shaft North prospect.

The company generated the new drill targets from a detailed interpretation of three lines of Induced Polarisation (IP) conductivity data and from soil geochemistry data.

Impact said the IP conductivity anomalies may represent massive sulphide bodies, such as that found at Main Shaft at the northern end of the Commonwealth deposit, where a relatively small massive sulphide lens about 50 metres by 50 metres by about 8 metres thick in size has an Inferred Resource of 145,000 tonnes at 4.5 grams per tonne gold, 4.8 per cent zinc, 1.7 per cent lead and 0.2 per cent copper (10g/t gold equivalent for 47,000 ounces of gold equivalent).

“The nature and location of the IP conductivity anomalies and their coincidence with strong lead-zinc-copper-in-soil anomalies is very encouraging for the discovery of further high-grade massive sulphide mineralisation,” Impact Minerals said in its ASX announcement.

“These new targets lie up to 200 metres west of and are separate to, other recently identified drill targets in IP chargeability data at the nearby Silica Hill prospect where Impact has discovered high-grade gold-silver mineralisation.

“The chargeability anomalies may represent disseminated sulphides.”

Black Rock Mining Achieves 99.6% Purity on Mahenge Graphite Optimisation

/in /by

THE DRILL SERGEANT: Black Rock Mining (BKT: ASX) announced results of initial metallurgical test work results from a flowsheet optimisation program being undertaken in Canada for the company’s Mahenge graphite project in Tanzania.

Black Rock Mining explained the primary composite ore sample from the project’s Ulanzi prospect achieved a marked increase in overall purity to 99.5 per cent, based upon size fraction assays or 99.6 per cent on the combined final concentrate.

Black Rock highlighted the results demonstrated high purities across the entire size fraction and that the very coarse flake fraction had been increased from previous test work, together with a reduction in very fine flake.

The company said the key outcome from this test was that exceptionally high purities in the 98.5 to 99.5 per cent range were immediately achieved.

Black Rock said this validated the straightforward processing attributes of Mahenge ore and improved flake size distribution.

The company suggested graphite at this high purity level will be sought after for battery and other applications and is expected to attract a price premium.

“The initial pilot plant test results confirm we have an exceptional ore that can be easily beneficiated into a high purity concentrate,” Black Rock Mining executive director and interim CEO John de Vries said in the company’s announcement to the Australian Securities Exchange.

“We were delighted to see we also have super jumbo flakes in our flake size distribution.

“We expected this, given earlier test work ground our flakes to a size where it was impossible to achieve the super jumbo sizing.

“We believe the results confirm we have the best ore of any development stage global graphite project.

“In addition, we now have confirmation of the highest purity and best flake size distribution in the market.

“This is a very positive outcome that will help our ongoing discussions with potential end users.”
