Alto Metals Identifies Additional Aircore Drilling Targets

/in , /by

THE DRILL SERGEANT: Alto Metals (ASX: AME) received the first batch of assays from a regional soil sample program on the company’s Sandstone project in Western Australia.

Alto Metals said the program had defined several new gold-in-soil anomalies between and around the Vanguard and Maninga Marley areas of the project.

The sampling demonstrated extensive gold in soil anomaly associated with Vanguard (and Vanguard North), and a new northeast trending anomaly halfway between Vanguard and Maninga Marley, and a strong and extensive gold in soil anomaly to the north and east of Maninga Marley, which complements a previous soil anomaly detected by Troy Resources.

The recent sampling program followed a compilation put together by Alto of a patchwork of soil sampling programs from various previous explorers.

The soil sampling program is to involve 3,000 samples over 17 target areas that Alto expects will, “fill in the gaps” in regard to its current knowledge base.

“To date, 1,654 soil samples have been collected and submitted for low level gold analysis, and results have been received from the first batch of 332 samples located between Vanguard and Maninga Marley,” Alto Metals said in its ASX announcement.

“The results of Alto’s two previous soil sampling programs, located over Vanguard and Maninga Marley indicated that gold in (residual) soils was more widespread than previously thought, and that further soil sampling at Sandstone could assist in the identification and ranking of gold targets for drill testing.

“The current soil sampling program is approximately 50 per cent complete, with another 1,400 samples planned to be taken.”

Alto Metals indicated a nominal 20,000 metre program of aircore drilling has been budgeted for drill testing soil anomalies at Vanguard, Maninga Marley, and a number of other prospects.

This work will commence in late May with RC drill testing to follow shortly thereafter.

This program includes a 5,000m aircore drilling program between and around Vanguard and Vanguard North, and these new soil results will add further holes and metres to that program.

Global Geoscience Reduces Rhyolite Ridge Leach Time and Acid Consumption

/in , /by

THE DRILL SERGEANT: Global Geoscience (ASX: GSC) announced the results of the latest acid-leach testwork carried out at the company’s 100 per cent-owned Rhyolite Ridge lithium-boron project in Nevada, USA.

Global Geoscience said the latest vat leach testwork demonstrated that over 90 per cent of the lithium and boron was extracted into solution in less than seven days.

The company said the decrease in leach time, acid consumption and solution requirements are expected to result in lower capital and operating costs than previously envisaged.

Latest results from the recent optimisation showed:

Much faster leach times of less than seven days – a reduction of more than 50 per cent;

Lower acid consumption of less than 400 kilograms of acid per tonne of feed – a reduction of more than 15 per cent;

Higher lithium and boron concentration in Pregnant Leach Solution (PLS), reducing mechanical evaporation requirements;

Faster, more selective leaching means lower levels of other elements in the PLS;

Continued high recoveries to PLS – greater than 90 per cent for both lithium and boron;

Preparation for vat leaching requires only a coarse crush of 25 millimetres; and

No grinding, agglomeration, high temperature or high pressure required.

“The latest vat leach results represent a significant improvement on already favourable acid-leach results and clearly demonstrate the advantages that vat leaching offers,” Global Geoscience managing director Bernard Rowe said in the company’s announcement to the Australian Securities Exchange.

“The rapid leach times, lower acid consumption and lower solution requirements are expected to have a very positive impact on both capital and operating cost estimates.

“The results bode well for the soon to be released trade-off studies being undertaken as Phase 1 of the Rhyolite Ridge Pre-Feasibility Study.

“Sulphuric acid will be the largest reagent cost and reducing acid consumption will have a very positive impact on operating costs.

“Vat leaching allows for much greater control of the leaching processing resulting in faster, more efficient and targeted leaching when compared to heap leaching.

“With a vat leach, we can control temperature, acidity (pH) and solution flow rates and this provides significant advantages over heap leaching.

“This control allows a more selective leach which recovers the lithium and boron, however, does not leach as many of the other elements into solution.

“Lower levels of other elements in the PLS has the benefit of simplifying the crystallisation and purification process steps.

“On-going metallurgical testwork is concurrently evaluating various attractive options to produce lithium carbonate and boric acid on site.”

Global Geoscience reiterated its claim that the Rhyolite Ridge is the only lithium deposit in the world that has been demonstrated to be amenable to simple acid leach processing, reinforcing it as an economically viable alternative to spodumene and brine deposits as a major, low-cost and long-term source of lithium.

Kalium Lakes Completes Beyondie BFS Drilling Campaign

/in , /by

THE DRILL SERGEANT: Kalium Lakes (ASX: KLL) has completed Bankable Feasibility Study (BFS) sonic monitoring bore installation and air-core geological programs at the company’s Beyondie sulphate of potash project (BSOPP) in Western Australia.

Kalium Lakes conducted some 8,504 metres of drilling throughout the program, which it said had continued to confirm the PFS Resource and Reserve Assumptions, reaffirming the project’s high-grade potassium results while indicating new aquifer targets.

The drilling returned potassium results up to 11,100 milligrams per litre (mg/L) – equivalent to a sulphate of potash (SOP) grade of 24,736mg/L.

The company has test pumping activities ongoing, with results being utilised to update the BFS numerical hydrogeological modelling of the project’s Ten Mile and Sunshine Stage 1 production areas.

Kalium Lakes explained the program is aimed at achieving future Measured Resources and Proved Reserves to support project financing requirements.

“The program has continued to confirm the Pre-Feasibility Study Resource model within our initial Stage 1 Mining Lease Areas,” Kalium Lakes managing director Brett Hazelden said in the company’s announcement to the Australian Securities Exchange.

“We envisage these results will enable an upgrade of the deposit to include a future Measured Resource and Proved Reserve, which in turn will support the Bankable Feasibility Study and project financing.

“The current assumed Stage 1 Area has a mine life of 23 years at 75,000 tonnes per annum SOP, when utilising our existing Probable Reserve, which has enabled Kalium Lakes to have very detailed discussions with both domestic and international offtake parties and financial institutions.”

Cassini Resources Eyes New Targets at Yarawindah Brook

/in , /by

THE DRILL SERGEANT: Cassini Resources (ASX: CZI) has identified new anomalies via results and interpretation of an Airborne Electromagnetic (AEM) survey carried out at the company’s Yarawindah Brook project in Western Australia.

Cassini Resources completed the AEM survey on the early stage nickel-copper-cobalt sulphide Yarawindah Brook exploration project in February.

According to Cassini, the survey identified several new conductive anomalies on the project, the strongest being a pair of anomalies, known as XC05 and XC06, in the western portion of the project.

These anomalies measure approximately 800 metres and 400 metres in strike respectively and are aligned along a strong regional structural trend, closely associated with a mafic/ultramafic intrusion.

The company collected nickel anomalous rockchip samples from outcrops immediately to the east of the conductors, however the anomalies themselves have no surface expression.

A third new anomaly, XC14, has an extent of 100m, and also appears to be associated with a strong NWSE trending structural feature in the centre of the project area.

Similarly, this anomaly has no surface expression.

“The company is highly encouraged by these early results, which supports the belief that the project has excellent potential to host significant bodies of magmatic nickel-copper-cobalt sulphides,” Cassini Resources said in its ASX announcement.

“The exploration team has begun planning for follow-up surface moving loop EM surveys over XC05, 06 and 14 to assist drill targeting.

“Drill testing is likely to occur at several targets including down-plunge testing of YWRC0083, as soon as practical, following the company’s current activities at West Arunta and Mount Squires.

“An RC drill program is due to commence at the West Arunta zinc project in June, pending heritage and environmental clearances.”

Kin Mining Extends Gold Mineralisation at Helens Deposit

/in , /by

THE DRILL SERGEANT: Kin Mining (ASX: KIN) released results from recent drilling at the Helens deposit, located within the Cardinia Mining Centre of the company’s Leonora gold project (LGP) in Western Australia.

Kin Mining conducted a total of 15 Reverse Circulation (RC) drill holes on the Helens project areas targeting extensions to the thick, high-grade mineralisation Kin intersected in 2017.

The company said the results from the March 2018 drilling have extended the Helens Main Lode mineralisation a further 75 metres south.

Helens Main Lode results included:

HE18RC160
14 metres at 3.08 grams per tonne gold from 88m;

HE18RCD161
8m at 8.6g/t gold from 88m; and

HE18RCD162
13m at 1.48g/t gold from 106m.

Kin said it is waiting to receive assay results from diamond drillholes targeting the Helens Main Lode, adding that mineralisation was intersected in each of these holes and the program provided insight into the continuity of gold-bearing lodes and the structural and lithological controls on the gold mineralisation.

“The recent drilling has indicated the untapped potential for resource growth within the LGP,” Kin Mining CEO Andrew Munckton said in the company’s announcement to the Australian Securities Exchange.

“In late 2017, wide, near surface intersections at above average grade, signalled that the Helens mineralisation continued further south.

“This recent drilling confirms those earlier results and illustrates the continuity of high-grade mineralisation down plunge towards the south.

“In addition, the discovery of new mineralised positions in close proximity to the established mineralisation at Helens indicates that significant opportunity lies ahead.

“The company will continue to target this lightly drilled area of the project.

“The geological team are continuing to develop the mineralising system model across a number of deposits at Cardinia and the increased use of diamond core drilling is proving invaluable in our understanding of the fundamentals of the mineralisation.

“Further work, is continuing.”

Marindi Metals Claims LCT Outcrop Discovery at Forrestania

/in , /by

THE DRILL SERGEANT: Marindi Metals (ASX: MZN) claimed an exploration breakthrough at the company’s 100 per cent-owned Forrestania project in Western Australia.

Marindi Metals announced the discovery of multiple outcropping specialised pegmatites, which the company declared to represent priority drill targets.

The company believes the outcropping (in-situ) lithium-caesium-tantalum LCT-type pegmatites could be the likely source of both the Tillerson and Scaramucci anomalies.

These were identified by the company’s newly-appointed managing director and CEO Simon Lawson, during an orientation site visit to the Forrestania project.

Lawson asserted the discovery of the potential source of the previously identified Tillerson and Scaramucci anomalies to be a pivotal breakthrough for the company, providing a series of drill-ready targets and reducing the need for further reconnaissance exploration work.

“This is an important step forward in our aggressive lithium exploration strategy at Forrestania,” Lawson said in the company’s announcement to the Australian Securities Exchange.

“These newly-defined outcrops are fixed-position, drill-ready specialised pegmatite targets that can be rapidly evaluated using definitive RC and diamond core sampling.

“On the basis of these finds, we will now pivot the majority of the planned reconnaissance-style aircore expenditure, as well as the costs for the associated drill-line establishment earthworks, and instead use those funds to undertake drilling to rapidly define the potential value of these pegmatites for shareholders.

“We have effectively eliminated the need for additional reconnaissance work by refining the geochemical soil sampling anomalies using simple boots-on-ground geological investigation – a great outcome for the company.

“We can now move immediately to begin planning an RC and diamond drill program, which we are aiming to kick off later this quarter.

“The potential of this belt for world-class lithium discoveries is amply demonstrated by the Earl Grey and Bounty lithium deposits, located around 50 kilometres along strike to the north.”

Sunstone Metals Encouraged by Limon Prospect Trenching Results

/in , /by

THE DRILL SERGEANT: Sunstone Metals (ASX: STM) received encouraging initial results from a surface trenching program at the Limon prospect, part of the company’s Bramaderos gold-copper project in Ecuador.

Sunstone Metals said the first batch of assays from the initial trench (LM-01) at Limon from trench LM-01 intersected 35.9 metres at 0.92 grams per tonne gold and 0.4 per cent copper, with the intersection at surface remaining open on all sides.

Peak copper and gold assays were 1.94m at 1.2g/t gold and 1.25 per cent copper and 2.06m at 1.74g/t gold and 0.41 per cent copper from separate samples.

The company explained that geological mapping, alteration mapping using spectral analysis, as well as soil and rock geochemistry all support its interpretation of the results of an outcropping window of a more extensive mineralised diorite body.

Sunstone said the results indicate that there are multiple targets for porphyry gold-copper mineralisation at the extensive Limon prospect.

“These initial trench results from Limon are extremely encouraging,” Sunstone Metals managing director Malcolm Norris said in the company’s announcement to the Australian Securities Exchange.

“This is a breakthrough result for our Bramaderos project, where we have now identified higher grade porphyry mineralisation at surface within a very large area of altered rock.

“Limon will be amongst the first areas to be drill tested, together with Bramaderos Main and West Zone targets.”

Intermin Resources Claims New Teal Project Gold Discovery

/in , /by

THE DRILL SERGEANT: Intermin Resources (ASX: IRC) claimed a new gold discovery from reverse circulation (RC) drilling being carried out on the company’s 100 per cent-owned Teal gold project, located 11 kilometres northwest of Kalgoorlie-Boulder in Western Australia.

Intermin Resources explained the drilling program is focussed on new discoveries and resource extensions at the company’s Teal, Anthill and Blister Dam projects.

As part of the program, 20,000 metres of RC and diamond drilling is underway for the Teal project area to grow the current resource base and test new discovery targets identified in the 2017 program.

Intermin has completed 26 holes for 3,156m to date testing high-priority new discovery targets, which has resulted in the discovery of a new prospect 200m east of Peyes Farm named Wills Find.

Wills Find returned promising gold mineralisation including:

PFRC18012
18 metres at 2.69 grams per tonne gold from 96m, including 11m at 4g/t gold from 96m;

PFRC1805
23m at 1.29g/t gold from 67m, including 10m at 2.13g/t gold from 78m; and

PFRC18013
3m at 1.28g/t gold from 128m.

Further new mineralisation was identified 400m north west of Yolande and 250m west of Teal, also returning encouraging levels of gold mineralisation including:

JFRC18012
4m at 2.6g/t gold from 54m.

Intermin Resources said the results confirm the presence of multiple parallel structures.

The company has extension drilling and testing of further new discovery targets ongoing.

“These latest drilling results provide further evidence of multiple parallel structures across the entire Teal project area and demonstrate the potential scale of the mineralised system,” Intermin Resources managing director Jon Price said in the company’s announcement to the Australian Securities Exchange.

“We are less than 20 per cent the way through our 55,000 metre drill program and look forward to testing the remaining new discovery targets and continuing with our resource growth program across 2018.”

Blackstone Minerals Commences Little Gem Drill Program

/in , /by

THE DRILL SERGEANT: Blackstone Minerals (ASX: BSX) commenced drilling at the company’s very high-grade Little Gem cobalt-gold project in British Columbia, Canada.

Blackstone Minerals explained the first hole in the current program is planned to intersect the entire target zone on the same section to the company’s previous drill hole which was abandoned halfway through the target zone yet encountered and intersection of 1.1 metres at 3 per cent cobalt and 44 grams per tonne gold, within 4.3m at 1 per cent cobalt and 15g/t gold.

Blackstone is planning an initial six diamond drill holes to test the original strike target zone of approximately 300m at Little Gem before looking to explore a strike extension of over one kilometre to the east and plus-500m strike extension to the west.

The company recently completed the final payment for Little Gem and is now the 100 per cent owner of project.

Blackstone indicated the initial results from its maiden drilling have been consistent with historic drilling and adit channel sampling, which returned average grades of 3 per cent cobalt and 20g/t gold.

“Blackstone is pleased to announce the company has commenced drilling at the very high-grade Little Gem cobalt-gold project in British Columbia, Canada,” Blackstone Minerals managing director Scott Williamson said in the company’s announcement to the Australian Securities Exchange.

“It has been a great effort by the team at Radius drilling in conjunction with our exploration team on site to establish the drill pad in the winter conditions.

“We look forward to the first assay results to be reported over the coming weeks, shareholders can expect more consistent news flow throughout the drill season as we explore the full potential of the Little Gem cobalt-gold project.”

Corazon Mining Identifies new Cobalt Anomalies at Mt Gilmore

/in , /by

THE DRILL SERGEANT: Corazon Mining (ASX: CZN) claimed discovery of three new cobalt anomalies at the company’s Mt Gilmore cobalt-copper-gold project in New South Wales.

Corazon Mining identified the anomalies while conducting an ongoing soil sampling program at Mt Gilmore.

The anomalies are located in the northern extent of the project at the Lantana Downs prospect approximately 12 kilometres north of the priority drill-defined Cobalt Ridge cobalt-copper-gold sulphide deposit.

The company said the discovery of the three high tenor soil anomalies – with up to 949ppm cobalt – further highlights the potential of the Mt Gilmore project to host a much larger cobalt system than it initially considered.

The current phase of exploration at Mt Gilmore is designed to identify new areas of cobalt mineralisation that have the potential to compliment the Cobalt Ridge deposit.

“The current area of exploration was historically explored for volcanogenic massive sulphide (VMS) deposits, with cobalt not previously tested,” Corazon Mining said in its ASX announcement.

“The basement rocks between Lantana Downs and Cobalt Ridge host numerous historical copper-gold sulphide workings, which provide the discovery potential for multiple Cobalt Ridge ‘lookalike’ deposits.”

Three soil anomalies have been defined based on geochemical signature and location.

The Southern Lantana Anomaly is very similar in tenor and multi-element association to that seen in the Cobalt Ridge soil-sampling program.

The cobalt-copper-gold anomaly is at the intersection of at least two mineralised trends and returned a peak cobalt assay of 151ppm.

The Central Lantana Anomaly has a cobalt-antimony-zinc-lead multi-element association with a peak cobalt result of 224ppm and in general appears to be a higher tenor than that observed in soil sampling at Cobalt Ridge.

The Northern Lantana Anomaly is located over what is interpreted to be a lateritic (weathered) serpentinised ultramafic.

Within the soil sampling results, cobalt peaks at 949ppm and nickel at 0.7 per cent, with the tenor of mineralisation increasing towards the north and east, yet to be closed off.
