De Grey Mining Hits Impressive Resource Definition Drilling Results at Brolga

/in , /by

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) reported resource infill drilling results from the Brolga zone within the company’s Hemi gold discovery near Port Hedland in Western Australia.

De Grey Mining is carrying out the drilling as part of a Prefeasibility Study (PFS) of the main Mallina gold project.

The Brolga zone was identified, along with Diucon and Falcon, in a Scoping Study De Grey completed in 2021 as one of the early proposed production sources for the project.

The company explained the Resource definition drilling allows more of the Brolga resource to be classified as JORC Indicated mineralisation.

New resource definition results include:

HEDD218
193 metres at 1.7 grams per tonne gold from 40m;

HMRC054
123m at 1.9g/t gold from 33m;

HEDD302
140.2m at 1.3g/t gold from 35.7m;

HMRC055
136m at 1.2 g/t gold from 38m;

HMRC065
128m at 1.2g/t gold from 94m; and

HMRC138
90m at 1.1g/t gold from 106m.

“These new resource definition drilling results at Brolga, including 193 metres at 1.7 grams per tonne gold in diamond drill hole HEDD218, successfully demonstrate the continuity of mineralisation within the proposed Brolga Stage 1 starter pit and reduce project risk associated with early production,” De Grey Mining general manager exploration Phil Tornatora said in the company’s ASX announcement.

“Resource extension drilling to the southwest of the proposed Brolga starter pit is in progress.

“Exploration drilling continues across both Greater Hemi and Regional areas.

“Resource definition drilling is nearing completion and rigs will then be targeting further resource extensional and discovery drilling within the Greater Hemi region.”

Ardea Resources Confirms Scandium and REE at Kalpini Nickel Project

/in , /by

THE DRILL SERGEANT: Ardea Resources (ASX: ARL) recently completed re-assaying of historic drill pulps from the company’s Kalpini nickel project in Western Australia.

Ardea Resources reported the re-assays have confirmed very high-grade historical nickel-cobalt intercepts and identified previously undocumented but significant scandium credits.

Additionally, notable Rare Earth Element (REE) and Rare Metal (RM) grades were indicated within the historic nickel-cobalt laterite mineralisation, including:

WERC0371
12 metres at 1.7 per cent nickel, 0.151 per cent cobalt, 28 grams per tonne scandium from 20m with;

0.244 per cent Total Rare Earth Oxide (TREO), includes neodymium (Nd), praseodymium (Pr), lanthanum (La), cerium (Ce); and

1.32 per cent Total Rare Metal Oxide (TRMO), includes titanium (Ti), yttrium (Y), zircon (Zr), niobium (Nb), hafnium (Hf), tantalum (Ta) and tungsten (W).

VKPRC0112
4m at 1.66 per cent nickel, 0.102 per cent cobalt, 40g/t scandium from 29m with;

0.1297 per cent TREO; and

0.7193 per cent TRMO.

“The Kalpini drill pulp re-assay was a major undertaking for Ardea in 2021, with the principal objective to validate historic resource drilling and obtain scandium assays for the current re-estimation of the full Kalgoorlie Nickel Project (KNP) Mineral Resource Estimate (MRE),” Ardea Resources managing director Andrew Penkethman said in the company’s ASX announcement.

“The importance of cobalt as a significant revenue contributor for the KNP was validated in the 2018 PFS.

“Significantly, the cobalt revenue credit reduced the then estimated C1 operating cost from US$5.59 per pound to US$0.42 per pound.

“If scandium and now REEs can be configured in the flowsheeet as additional revenue contributors, there are significant improvements to the already robust KNP financial metrics.

“These studies are all subject to the current Ardea-ALS bench-scale metallurgical R&D, where material with REE and RM credits are targeted in R&D programs.

“These R&D programs for Ardea are specifically targeting Critical Minerals, as supply chain security is more important than ever as the World continues the transition to a low carbon future.”

Kalamazoo Resources Achieves Excellent Metallurgy Results at Mt Olympus

/in , /by

THE DRILL SERGEANT: Kalamazoo Resources (ASX: KZR) reported results of initial metallurgical test work carried out on several zones within the Mt Olympus gold deposit, part of the company’s Ashburton gold project Western Australia.

Mt Olympus is a large component of Kalamazoo’s 1.65 million ounces of gold mineral resource at the Ashburton gold project.

Kalamazoo Resources carried out the work to determine whether the Indicated and Inferred 15.12 million tonnes at 2.2 grams per tonne gold for 1.08 million ounces Mt Olympus resource would be amenable to the production of a high-grade gold sulphide concentrate via an industry standard crush-grind-float processing circuit, commonly used world-wide on many refractory style gold deposits.

The test work was also used to confirm results from previous work completed by Northern Star Resources (ASX: NST) in 2011-12, when it owned the Ashburton gold project.

The tests achieved excellent gold recovery into an initial rougher concentrate of up to 94 per cent with gold in concentrate grades averaging 31.8g/t gold across all four composites with a maximum value of 39.2g/t gold.

“We are extremely pleased with this initial phase of metallurgical test work at Mt Olympus which substantially de-risks the potential development of our Ashburton gold project in the Pilbara,” Kalamazoo Resources executive director Paul Adams said in the company’s ASX announcement.

“Given these positive results, we have immediately commenced the next phase of the metallurgical program which will optimise the flowsheet to enhance performance even further.

“The flowsheet was designed to include a multi-phase cleaner process on the initial rougher concentrate.

“This work had not been performed previously and we are encouraged to see the very significant difference that this has made to the final concentrate grade, especially as this work has yet to be optimised and gravity recovery work is still pending.”

White Rock Minerals Chasing Global Commodities

/in , , /by

COMMODITY CAPERS: White Rock Minerals (ASX: WRM) describes itself as being a near-stage gold producer and poly-metallic and precious metals explorer.

The company’s aspirations are spread across a portfolio of three projects: the Woods Point gold project in Victoria, the Red Mountain silver-zinc VMS and Last Chance IRGS gold projects in Alaska USA, and the advanced gold and silver Mt Carrington project in News South Wales.

White Rock believes its portfolio provides investors with diversification through high-quality projects at differing developmental stages, exposed to different commodities, in two first world jurisdictions.

White Rock recently updated the Inferred Mineral Resource estimate for the Red Mountain project thanks to a doubling of the Dry Creek deposit high-grade Inferred Mineral Resource to 4.9 million tonnes at 8.4 per cent zinc equivalent or 393 grams per tonne silver equivalent (at a 3% Zn cut-off).

Dry Creek joins the West Tundra Flats as the most significant deposits within the Red Mountain project combining for a high-grade Inferred Resource of 11.6 million tonnes at 12 per cent zinc equivalent or 555g/t silver equivalent (at a 3% Zn cut-off).

The global Inferred Mineral Resource for Red Mountain now stands at 21.3 million tonnes at 8.5 per cent zinc equivalent for 1.8 million tonnes of contained zinc equivalent or 393g/t silver equivalent for 207 million ounces of contained silver equivalent.

Much of White Rock’s attention of late, however, has been focused on advancing its Woods Point gold project north-east of Melbourne in Victoria, which the company acquired in 2021.

Woods Point contains 660 square kilometres of highly prospective exploration ground that has seen historical production of more than 1,600,000 ounces of gold.

Along with the land holding, Woods Point also contains the Morning Star gold mine, which came complete with mining licenses, operational shaft and winder, underground workings, and a gold processing plant.

Over its lifetime, the Morning Star mine produced over 883,000 ounces of gold at an average grade of 26.5g/t.

 

 

 

 

With production now halted, White Rock has taken on the project with its focus on in-mine exploration, with the goal of following up high-grade gold potential in specific zones of the mine to define a long-term resource and mine plan, before considering a restart of production.

The most recent news from Morning Star came from an underground drilling foray that produced further assay results from the Kenny’s target area.

The Kenny’s target area includes multiple high-grade gold structures including the Whitelaw Reef, the Upper and Lower Burns Reefs, and the Upper and Lower Campbell Reefs.

This target area is located between 6 Level and 9 Level, where existing development provides access to the Whitelaw Reef and the immediate high-grade target area that White Rock is currently assessing for its future mining potential.

 

 

 

 

 

 

 

 

 

 

 

 

Recent drill intersection assay results from the Whitelaw Reef, include:

22KPL9002
4.3 metres at 9.3 grams per tonne gold, including 0.3m at 68.3g/t gold (true width); and

22KPL9004
0.2m at 56.6g/t gold (true width).

These results followed previous drilling results from the Whitelaw Reef, which included:

21L7006
0.8m at 34.1g/t gold, including 0.3m at 107g/t gold (true width); and

MS402
0.6m at 74.8g/t gold (true width).

White Rock has since moved the underground drill rig to the southern end of the mine, still on 9 Level, where it is completing definition drilling on extensions to the recently mined McNally Reef with a view to re-commencing mining in the near term.

The underground drill rig will then resume drill testing the prospective Gap Zone between 10 Level and 14 Level in conjunction with continuing to drill nearer-term production targets above 9 Level as it progresses through different drill sites along 9 Level.

While the McNally Reef is being drilled, White Rock will undertake a mining assessment of the Whitelaw Reef to determine whether it can be included in future development and production plans or requires additional drilling to reach a decision point.

The company believes these current drill programs potentially deliver four working areas for future mining, dependent on the outcome of an assessment of drilling results for each, providing a pathway to recommence mining at:

1. McNally Reef extensions where development is in place to commence mining immediately;

2. Dickenson Reef where sufficient development is in place to commence mining in the short term;

3. Stacpoole / Age of Progress Reefs where development is in place and minor infrastructure requirements will allow mining to commence in the short term; and

4. Whitelaw Reef where minor development is required, and more substantial infrastructure is needed to enable mining to commence in the mid-term.

Miramar Resources Identifies Nickel Sulphide Targets at Gidji JV

/in , /by

THE DRILL SERGEANT: Miramar Resources (ASX: M2R) informed the market of it has identified what it considers potential for nickel sulphide mineralisation within the company’s 80 per cent-owned Gidji JV project in the Eastern Goldfields of Western Australia.

Miramar Resources has been actively exploring at Gidji since listing on the ASX in October 2020 as it believes potential exists for discovery of one or more large gold deposits within its strategic 60 square kilometre land package located 15km north of Kalgoorlie.

The company has conducted a review of new and historic data over the Gidji JV project with a focus on the potential for nickel sulphide mineralisation.

This has shown the Gidji JV project contains approximately 10km of strike of various ultramafic units, including the ‘Highway Ultramafic’, which hosts the Scotia and Saints nickel sulphide deposits further to the north.

A cluster of highly anomalous nickel and copper results were identified where the magnetic signature of the Highway Ultramafic is strongest, which Miramar said may indicate the thickest part of the sequence.

The highest nickel and copper results also occur in an area of structural complexity where NE-trending faults crosscut the earlier stratigraphy.

“It’s well known that gold and nickel mineralisation occur in close proximity at many places within the Eastern Goldfields region,” Miramar Resources executive chairman Allan Kelly said in the company’s ASX announcement.

“Although the Highway Ultramafic hosts nickel sulphide deposits in at least two locations along the Boorara Shear/Bardoc Tectonic Zone, there has been minimal targeted nickel exploration at Gidji.

“The new nickel sulphide targets we have identified again confirm how underexplored the Gidji project is, not just for gold, but for other commodities as well.”

Carawine Resources Hits Highest Grade to Date at Hercules

/in , /by

THE DRILL SERGEANT: Carawine Resources (ASX: CWX) released the latest assay results from an ongoing drilling program at the Hercules prospect, part of the company’s Tropicana north project in the north-eastern goldfields of Western Australia.

Carawine Resources reported the assays had returned the highest gold grade and one of the best intervals from drilling at the prospect to date, including:

TNDD014
4 metres at 40.1 grams per tonne gold from 239m, including 1m at 137g/t gold from 239m; and

TNDD013
1m at 23.9g/t gold from 192m.

Hercules is described by Carawine as an advanced gold prospect held by the company’s Thunderstruck Joint Venture (Carawine 90% interest) within the Tropicana North project.

Gold mineralisation at Hercules is hosted by multiple parallel veins and shears within a wide, steeply dipping mineralised zone striking northeast.

To date, mineralisation has been reported along a 340m strike length, extending from 35m to 250m below surface, and remains open.

“Hercules has delivered, with today’s results including the highest gold grade returned from the prospect to date and increasing the size of the high-grade gold zone, which remains open to the north, south and at depth,” Carawine Resources managing director David Boyd said in the company’s ASX announcement.

“This supports our belief that Hercules is a significant gold discovery.

“We will continue to target extensions to the main zone of high-grade mineralisation at Hercules, with assay results pending from three recently completed holes, and at least five more holes planned in the current program.

“We look forward to sharing the results of this drilling over coming months, along with results from recently completed drilling at the nearby Big Freeze and Beanie prospects, and the planned commencement of regional drilling programs across the Tropicana North project.”

Hammer Metals Achieves Big Copper Hit at Ajax

/in , /by

THE DRILL SERGEANT: Hammer Metals (ASX: HMX) released laboratory assay results for a previously reported high-grade copper-gold sulphide intercept at the 100 per cent- owned Ajax prospect, within the company’s Mt Isa exploration portfolio in northwest Queensland.

Hammer Metals explained the lab results to have upgraded the previously reported p-XRF intercept at the Ajax prospect, returning assay results of:

HMLVRC014
11 metres at 5 per cent copper and 2.5 grams per tonne gold from 24m, within a broader interval of 16m at 3.5 per cent copper and 1.8g/t gold from 22m.

“It’s extremely pleasing to see a significant upgrade to the preliminary assay results at Ajax,” Hammer Metals managing director Daniel Thomas said in the company’s ASX announcement.

“Copper grades above five per cent are rare, especially with the potential relationship of this intercept to a nearby sizeable geophysical target.

“Given the absence of graphite in the immediate area, the conductor may represent a prospective sulphide horizon.

“The corresponding strong copper and gold geochemistry at surface presents Ajax as one of the more exceptional exploration targets that I have observed.

“Another high-quality target has now been added to our drilling sequence.”

Hammer indicated the identified mineral horizon at Ajax defined by hole HMLVRC014 will be followed up with drilling along strike and at depth to determine the potential geometry of the system.

The testing of the EM target zone to the east of Ajax has been prioritised with Hammer undertaking additional cultural clearances and finalising its land access arrangements.

The hole will be tested with diamond drilling with initial indications that drilling will commence once landholder negotiations have been finalised.
