Piedmont Lithium Confirms Ore Body Pure Spodumene Nature

THE DRILL SERGEANT: Piedmont Lithium (ASX: PLL) completed mineralogical testing, comprising semi-quantitative and quantitative x-ray diffraction (XRD) analysis, on samples of mineralised pegmatites and composite samples from the company’s Core, Central, and Sunnyside properties in North Carolina, USA.

Piedmont dais it has been advised that the relatively pure spodumene character of its ore body is unusual and highly positive, allowing for a simplified flowsheet to produce strong lithium recoveries.

A total of 36 samples of mineralised pegmatites were collected from Piedmont’s Core, Central, and Sunnyside properties.

The resulting data demonstrated the Piedmont ore body to not contain any petalite, lepidolite, or zinnwaldite – non-spodumene lithium bearing minerals concentrate under different operating conditions than spodumene when processing with dense medium or flotation.

The company explained that petalite (4.86% lithium dioxide (Li2O)) and lepidolite (7.7% Li2O) have lower lithium content than spodumene (8.03%).

Because the numbers are in its favour, Piedmont expects to maintain both high lithium concentrate grades and recoveries at the company’s planned concentrator in part due to the absence of petalite or other lithium bearing minerals.

“As the market’s understanding of lithium processing evolves, it will become increasingly clear that mineralogy and metallurgy are the fundamental building blocks of a successful hard-rock lithium business,” Piedmont Lithium president and CEO Keith D. Phillips said in the company’s announcement to the Australian Securities Exchange.

“Our testwork confirms what we have always suspected – the Carolina Tin-Spodumene Belt is exceptional not only in scale but in terms of mineralogy.

“When combined with the shallow nature of our ore body and the capital and operating cost advantages of our location, we are excited about the upcoming resource, metallurgical and scoping study updates.”

Comet Resources Identifies Large Graphite Target

THE DRILL SERGEANT: Comet Resources (ASX: CRL) has identified a large, priority exploration target immediately to the north east of the company’s existing Springdale graphite resource in Western Australia.

Comet Resources believes the target could be a fold repeat of graphite-bearing stratigraphy that hosts the current high-grade Springdale resource that consists a defined Inferred Resource of 15.6 million tonnes at 6 per cent total graphitic carbon (TGC), including a high-grade portion of 2.6 million tonnes at 17.5 per cent TGC.

The company’s interpretation of a recent regional aeromagnetic survey identified a potential fold-repeat of graphite-bearing stratigraphy eight kilometres east-north-east of the defined resources.

The scale of the folding presents a target of approximately seven square kilometres.

The target sits in a similar, favourable fold-closure position to the one that already hosts the high-grade graphite resource.

Comet said its ability to target shallow, high-grade graphite mineralisation using electromagnetic surveys (EM) was confirmed during its February drilling campaign with the discovery of two new zones.

The company’s exploration to date has focussed on the fold closure of a northeast-southwest trending syncline.

Recent interpretation of the regional aeromagnetic survey has highlighted a potential fold-repeat of graphite-bearing stratigraphy to the east-north-east of the existing resource.

Comet plans to use EM as a high-grade targeting tool to test the newly identified area.

“We don’t yet know if we have found the highest-grade areas of graphite mineralisation at Springdale,” Comet Resources CEO Philippa Leggat said in the company’s announcement to the Australian Securities Exchange.

“The highest intercept of one metre at 48 per cent TGC was retuned in our February drilling program.

“The two new discoveries made in the program are outside the current resource and clearly confirmed the potential to use EM to target the high-grade zones near surface, and that is really quite exciting.

“We already have an Inferred Resource of 2.6 million tonnes at 17.5 per cent TGC on less than ten percent of our licence, mostly within 60 metres of surface, and this is before we look at the potential that a fold repeat could deliver.

“Moving forward, we see EM helping to identify the highest grade in new areas and around the existing resource, so that we can cost-effectively upgrade the high-grade component of our project.”

Cassini Resources Encounters Multiple High-Grade Copper Hits at One Tree Hill

THE DRILL SERGEANT: Cassini Resources (ASX: CZI) declared recording the best results to date from drilling underway at the One Tree Hill prospect within the West Musgrave project (WMP) in Western Australia.

Cassini Resources explained the ongoing exploration program is being funded as part of the company’s Joint Venture Agreement with OZ Minerals (ASX: OZL).

The JV is currently undertaking a Pre-feasibility Study (PFS) on the Nebo-Babel deposits in conjunction with a regional exploration program across the WMP.

The latest results stem form drill hole CZD0099, which returned high-grade results including:

9 metres at 2.56 per cent copper, 0.37 per cent nickel, 0.06 per cent cobalt and 1.32g/t PGE from 344m within a broader disseminated zone of 40m at 1.16 per cent copper from 343m (Zone B)

6.2m at 3.61 per cent copper, 0.11 per cent nickel, 0.03 per cent cobalt and 0.51g/t PGE from 435.8m within 22m at 1.80 per cent copper from 435m (Zone C)

0.75m at 1.71 per cent Ni, 0.52 per cent copper, 0.10 per cent cobalt and 2.67g/t PGE from 133m within 44.7m at 0.35 per cent copper from 116.3m (Zone A).

Cassini described the results as encountering, “the first significant zone of nickel-rich massive sulphides at this prospect”.

Four distinct zones of mineralisation were intersected in the hole:

Zone A. Predominantly disseminated copper mineralisation in a meta-gabbro intrusion starting at 100m below surface.

Zone B. A broad zone of mineralised meta-gabbro with a copper-rich massive sulphide at the top of the unit.

Zone C. A second broad zone of copper-rich gabbro, also with a massive sulphide component at the top of the unit.

Zone D. A very narrow massive sulphide zone that corresponds with the target EM conductor.

“CZD0099 has exceeded our expectations,” Cassini Resources managing director Richard Bevan said in the company’s announcement to the Australian Securities Exchange.

“We’ve intersected several mineralised zones that were effectively blind to previous geophysical modelling, and this presents real opportunities for further exploration success.

“It’s also worth recognising that whilst this is only our sixth hole at the One Tree Hill prospect, it is showing all the hallmarks of a major mineralised system with the potential to add future mine life and value to the West Musgrave Project.

“The exploration results continue to confirm the excellent prospectivity and potential of the project.”

Cassini indicated it considers high resolution magnetic data very important for future exploration at One Tree Hill, however, the current magnetic data it possesses is relatively coarse and does not allow confident mapping of lithologies and structures at the prospect scale.

This being the case, the company has an airborne magnetic survey planned to be carried out prior to follow-up drilling that will extend west across the tenement boundary into Cassini’s 100 per cent-held Mt Squires project to assist exploration at both projects.

The survey will also extend north east to ensure complete high-resolution coverage of the entire extent between One Tree Hill and Nebo-Babel.

Cassini said it expects the surveying and processing will be completed by the end of July, from which the interpretation of new magnetic data will assist follow-up drill targeting.

The relatively shallow nature of the upper parts of this system means that at least that part is amenable to testing by RC rather than Diamond drilling, which is both faster and cheaper.

Exore Resources Confirms Veronique Gold Discovery

THE DRILL SERGEANT: Exore Resources (ASX: ERX) declared that results from ongoing shallow aircore (AC) drilling had confirmed the company’s emerging Veronique gold discovery in northern Cote d’Ivoire.

Exore Resources said the results had provided progress towards the company’s objective of defining a multi-million-ounce gold project in northern Cote d’Ivoire.

The ongoing AC drilling at Veronique intersected high-grade, shallow gold mineralisation the company said produced evidence of a new gold discovery with large-scale potential.

Results from the latest broad-spaced, shallow AC drilling include:

12 metres at 7 grams pe tonne gold from 16m;
12m at 3.12g/t gold from 36m;
1m at 38.01g/t gold from 28m (EOH); and
8m at 2.23g/t gold from 48m.

“We remain extremely excited about the potential for a large-scale gold discovery at Veronique with these latest exceptional shallow aircore results,” Exore Resources managing director Justin Tremain said in the company’s announcement to the Australian Securities Exchange.

“This latest drilling has resulted in an interpreted WNW strike orientation to the mineralisation which opens up the potential for a large array of kilometre scale sub-parallel mineralised lodes across many kilometres in width.

“The improved confidence in the strike orientation allows for ongoing infill and step out aircore drilling during the wet season in preparation for maiden RC drilling at the start of the dry season.”

Cygnus Gold Extends Bencubbin North Nickel Anomalism

THE DRILL SERGEANT: Cygnus Gold (ASX:CY5) extended nickel anomalism on the back of further results from soil sampling over the Bencubbin North nickel and base metals prospect within the company’s wholly owned Bencubbin project in the Wheatbelt region of Western Australia.

Cygnus Gold completed an additional 267 auger soil samples it claims to have extended its original nickel auger soil results noting the nickel anomalism is associated with widespread copper and PGE anomalism.

The company reported that a total of 74 samples assayed for PGEs were also anomalous, with maximum values of palladium (Pd) of 44.4ppb (associated with 5.5ppb Platinum) and maximum platinum of 11.8ppb (with 35ppb Pd).

Cygnus Gold explained that similar levels of PGE anomalism in soils are commonly associated with mineralised nickel sulphide systems elsewhere in the WA Goldfields, which it considers demonstrates potential for magmatic nickel sulphides at Bencubbin.

“The Bencubbin nickel and base metals project is shaping up as a high priority asset for the company, with sampling confirming the prospectivity of the northern section of more than 70 kilometres of untested prospective stratigraphy,” Cygnus Gold managing director James Merrillees said in the company’s announcement to the Australian Securities Exchange.

“The company also acknowledges the WA Government awarding $150,000 in EIS funding towards drilling at Bencubbin.

“This recognises the technical merits of the project, as well as the underlying prospectivity of the WA Wheatbelt.”

With the surface sampling having extended the nickel-copper and copper-lead-zinc prospectivity at Bencubbin North, outlining widespread PGE anomalism consistent with potential for magmatic nickel-copper sulphide mineralisation, Cygnus Gold declared it intends carrying out infill sampling to refine targets for drill testing with sampling to commence on the highest priority targets in the middle of this month.

Cygnus is also planning to commence sampling on the Bencubbin South tenement over extensions of the Bencubbin Greenstone as well as further sampling of the Mandiga Trend, located at the southern end of Bencubbin North project, which it considers highly prospective for base metals.

Drilling is planned in the second half of the year once it has received and interpreted these results.

VRX Silica Upgrades Muchea Mineral Resource Estimate

THE DRILL SERGEANT: VRX Silica (ASX: VRX) completed drilling at the company’s Muchea silica sand project north of Perth in Western Australia that has led to an upgraded Mineral Resource Estimate.

VRX Silica announced the JORC 2012 Mineral Resource Estimate for the Muchea silica sand project, which has been upgraded to 208 million tonnes at 99.6 per cent silicon dioxide (SiO2) comprising a 49 per cent increase to the JORC 2012 Indicated Resource estimate of 29 million tonnes at 99.6 per cent SiO2 and a four percent increase to the JORC 2012 Inferred Resource estimate of 179 million tonnes at 99.6 per cent SiO2.

“This drill program is over an area of 217ha, which is still only a small portion of the 2,900ha Mining Lease Application area,” VRX Silica managing director Bruce Maluish said in the company’s announcement to the Australian Securities Exchange.

“Testwork indicates that high-grade silica sand can be produced from Muchea for which there is strong demand for glassmaking in Asia.

“With low variability of results over the Resource area our expectation is that the majority of the Indicated Resource will convert to Probable Reserves in our impending BFS.”

The company explained the Resource estimate only includes sand three metres above the year 2000 mapped water table level and discounts the top half metre of topsoil, which will be used for rehabilitation.

VRX claims metallurgical testwork it has carried out to-date confirms its updated silica sand model to be readily amenable to upgrading by conventional washing and screening methods to produce a high-purity silica sand product with high mass recoveries.

The high-purity silica sand product specifications are expected to be suitable for industries such as the glass making and foundry industries.

VRX Silica anticipates that further testwork focusing on currently discounted sand layers may result in further reinterpretation and upgrades to the Muchea MRE.

The company indicated future drilling and estimations will include this zone of sand which is expected to add to the Resource inventory.

A more extensive Program of Work (PoW) has been lodged to enable an aircore drill program over areas that have been previously hand augered.

Drilling is planned for the September quarter 2019.

St George Mining Assays Confirm High-Grade Drill Hits

THE DRILL SERGEANT: St George Mining (ASX: SGQ) announced further thick intercepts of high-grade nickel-copper-cobalt-PGE sulphide mineralisation from Phase 1 of its 2019 drill program at the company’s Mt Alexander project in Western Australia.

St George Mining said it had received assays indicating that drilling had intersected nickel-copper sulphide mineralisation with the best intersections being at the Investigators prospect.

Laboratory assays for hole MARC118 confirmed thick intersections of high-grade nickel-copper-cobalt-PGE mineralisation of:

10 metres at 2.47 per cent nickel, 1.06 per cent copper, 0.07 per cent cobalt and 2.52 grams per tonne PGEs from 142m, including 3m at 3.85 per cent nickel, 2.12 per cent copper, 0.11 per cent cobalt and 4.22g/t PGEs from 145m and 2m at 5.04 per cent nickel, 1.47 per cent copper, 0.16 per cent cobalt and 2.12g/t PGEs from 150m.

St George explained that hole MARC118 was drilled along the north-south MAD60 Line at Investigators, where high-grade nickel-copper sulphide mineralisation had previoulsy been intersected from very shallow depths of 25m below surface and extending down-plunge for a length of more than 380m.

The company said the 10m thick high-grade intercept in MARC118 greatly extends the continuity of mineralisation on the north-south trending MAD60 Line.

High-grade mineralisation was also intersected in hole MARC109, which was drilled approximately 200m to the west-northwest of MARC118.

Assays for MARC109 returned:

4m at 1.21 per cent nickel, 0.47 per cent copper, 0.04 per cent cobalt and 0.99g/t PGEs from 200m, including 2m at 2.04 per cent nickel, 0.83 per cent copper, 0.07 per cent cobalt and 1.67g/t PGEs from 202m.

“The latest high-grade intersections at Investigators establish further continuity to the scope and scale of mineralisation at Investigators,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.

“Ongoing step-out drilling is being planned for Investigators, with two SAMSON EM anomalies in the northern section of the prospect area lined up as high-priority targets for the upcoming drill program.

“The SAMSON anomalies are corroborated by data from two separate geophysical surveys – the recent Sub-Audio Magnetics (SAM) survey as well as a prior moving-loop EM survey, and are compelling drill targets for the discovery of additional mineralisation.”

Tanga Resources Commences Hagenhof Drilling in Namibia

THE DRILL SERGEANT: Tanga Resources (ASX: TRL) announced drillinhg has commenced at the company’s Hagenhof copper project in Namibia.

Tanga Resources explained the program has been updated to now consist of approximately 3,000 metres of diamond and Reverse Circulation (RC) drilling to test copper mineralisation at several targets at Hagenhof.

The company had to revise its previously announced RC drill program due to an unexpected delay in the arrival of an RC rig from South Africa, resulting in the drilling contractor providing a track mounted diamond drill rig, at no additional cost to the company, until the RC drill rig arrives, at which time the program will revert back to RC drilling.

“Diamond drilling has commenced at the Main Gossan targeting a prominent ground magnetic anomaly and will test the strike, plunge and grade of the historically reported copper mineralisation,” Tanga Resources said in its ASX announcement.

“It is expected that RC drilling will then test the prominent magnetic anomaly coinciding with a large interpreted structural domal feature at Liv’s Hill, before going on to test copper mineralisation at Jette’s Hill, Copper Cap and P5; all of which have never previously been drilled.”

De Grey Mining Scores Further High-Grade Intercepts at Toweranna

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) released results for an additional 17 RC drill holes undertaken at the company’s Toweranna gold deposit in the Pilbara of Western Australia.

De Grey Mining has now completed the RC program with a total of 42 holes drilling in advance of 10,126 metres.

The company explained the RC drilling was undertaken on a 40m by 40m basis to allow for an open pit resource estimation to 200m depth, targeting lateral and depth extensions to the existing shallow 2018 Toweranna Mineral Resource of 2.01 million tonnes at 2.2 grams per tonne gold for 143,900 ounces.

De Grey stated the new drilling results confirm lateral extensions and additional stacked lodes and add further support to an anticipated substantial increase to the current open pit resource to 200m depth.

Potential to extend gold lodes beyond 200m is currently being evaluated with selected scout diamond holes testing for mineralisation between 200 to 600m depth.

Latest RC results include:

TRC153
11 metres at 2.11 grams per tonne gold from 45m;

TRC164
8m at 2.71g/t gold from 31m, including 3m at 6.73g/t gold from 35m;

TRC157
7m at 9.27g/t gold from 209m, including 1m at 25.5g/t gold from 209m, including 1m at 17.85g/t gold from 212m; and

15m at 4.71g/t gold from 223m, including 3m at 8.55g/t gold from 223m, including 1m at 37.1g/t gold from 235m.

TRC158
12m at 2.23g/t gold from 195m;

13m at 1.61g/t gold from 217m; and

23m at 1.54g/t gold from 246m.

“De Grey continues to successfully establish strong shallow gold mineralisation at Toweranna,” De Grey Mining technical director Andy Beckwith said in the company’s announcement to the Australian Securities Exchange.

“Toweranna continues to open our eyes to this new style of gold mineralisation.

“We don’t know how big Toweranna can be just yet as it remains open and is only constrained by the limit of drilling.

“This next phase of deeper scout diamond drilling will give us an indication of the resource potential between 200 to 600 metres depth.”
