De Grey Mining Claims New Gillies Gold Discovery

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) claimed a new gold discovery, located 30 kilometres southwest of the company’s Hemi gold discovery in Western Australia.

De Grey Mining identified a new shear hosted gold target via broad spaced RC drilling at the Gillies prospect, situated within the Farno Joint Venture.

De Grey undertook the drilling to increase its equity from 30 per cent to 75 per cent interest in the JV that involves tenement E47/2502 where De Grey is manager with TSX-listed Novo Resources Inc (TSX: NVO) its 25 per cent partner.

A follow-up RC drilling program is already planned for Q2 2021 along with additional aircore drilling is planned to test numerous bedrock gold anomalies, including several Hemi style intrusion targets within the Farno JV.

“Gillies is shear zone hosted, similar to Withnell, Wingina, Mallina and Mt Berghaus, which make up a significant portion of the company’s regional 2.2 million ounce existing endowment,” De Grey Mining managing director Glenn Jardine said in the company’s ASX announcement.

“Exploration within the Farno JV area is at a very early stage however this new gold system provides strong evidence on the potential of the region.

“De Grey has formed a dedicated regional exploration team which is preparing for the company to restart exploration outside of the Greater Hemi area, in parallel with extensional and exploration work within the Greater Hemi area.

“We anticipate following up the Gillies discovery hole in the next quarter.”

De Grey Mining Continues Crow/Aquila Expansion

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) has drilled further growth at the Crow and Aquila zones within the company’s Hemi gold discovery, south of Port Hedland in Western Australia.

Drilling at the Crow zone expanded the main lode – McLeod – that is now identified over 600 metres strike, 300m depth and up to 60m true thickness and remains open.

New results in the McLeod lode at Crow include:

HERC607
33 metres at 4.9 grams per tonne gold from 171m, including 11m at 12.1g/t gold from 171m;

HERC039D
24.8m at 2.1g/t gold from 308.19m;

HERC355
7m at 3.9g/t gold from 215m; and

HERC611
18m at 1.3g/t gold from 55m.

Additional new intercepts in other lodes at Crow returned:

HERC535
6m at 6.9g/t gold from 57m;

HERC623
18m at 3.4g/t gold from 210m; and

HERC310D
14.3m at 2.9g/t gold from 239.5m.

Drilling at the Aquila zone has defined over 800m strike and recent results have highlighted plunging higher-grade shoots at the eastern and western ends of the intrusion.

New extensional results include:

HEDD012
52.2m at 2g/t gold from 519.83m, including 15.3m at 4.5g/t gold from 556.68m;

HERC208D
12m at 3.6g/t gold from 371m including 0.5m at 71.3g/t gold from 374.77m, and 27.1m at 1.2g/t gold from 405m that intersected the eastern end of the McLeod Lode; and

HERC250D
24.6m at 1.7g/t gold from 293.2m.

“The large Crow/Aquila gold system continues to expand and be defined across multiple stacked subvertical lodes,” De Grey Mining managing director Glenn Jardine said in the company’s ASX announcement.

“The dominant lodes of McLeod and Aquila are oblique to each other, intersect at the eastern end and are expected to support a combined open pit scenario.

“Both lodes demonstrate high-grade mineralisation that should also provide underground mining potential below any open pit mining limits.

“The ongoing systematic infill RC drilling program at Crow has improved our understanding of the continuity of mineralisation.

“Step out drilling continues to extend mineralisation at all zones at Hemi.

“RC drilling also continues at the recently discovered Diucon and Eagle zones to the immediate west.”

De Grey Mining Defines Depth Extensions and New Footwall Lodes at Falcon

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) has defined further mineralisation at the Falcon intrusion, part of the company’s Hemi gold discovery in Western Australia.

De Grey Mining reported the mineralisation has been defined over a strike length of approximately one kilometre and is associated with highly brecciated and extensively sulphide altered portions of the north-south orientated subvertical intrusion.

The company said the style and intensity of alteration and brecciation is similar to its nearby Aquila deposit.

The latest results include:

HERC400DW1
55 metres at 1 gram per tonne gold from 263m and 16.5m at 1.1g/t gold from 324.5m − within an overall zone of 111.2m at 0.8g/t gold from 239.8m.

The company explained this to be currently the deepest hole showing mineralised intrusion that extends to 450 below surface.

HERC401D
24m at 0.9g/t gold from 302m and 12.5m at 1.3g/t gold from 331m − within an overall interval of 57m at 0.8g/t gold from 299m.

“The latest extensional drilling at Falcon demonstrates the increasing scale of the zone with mineralisation now intersected over one-kilometre strike and over 350 metres in depth,” De Grey Mining general manager exploration Phil Tornatora said in the company’s ASX announcement.

“New 160 metres spaced step out diamond drilling is underway to extend mineralisation to approximately 450 metres depth.

“The intrusion is increasing to approximately 100 metres thick at depth and multiple new footwall lodes are beginning to develop.

“Infill drilling is also providing confidence in the continuity and consistency of gold mineralisation.

“Falcon is open at depth and deeper step out diamond drilling is being prioritised to test this potential.

“These recent results, and further depth extensions, have the potential to significantly increase the already substantive gold endowment at Falcon.”

De Grey Mining Metallurgic Testwork Confirms High Recoveries

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) reported results from a metallurgical testwork program undertaken at the company’s Hemi and regional deposits, south of Port Hedland in Western Australia.

De Grey Mining is conducting a comprehensive metallurgical testwork program across each of the mineralised zones at Hemi (Brolga, Aquila, Crow and Falcon) and the regional deposits of Mallina and Withnell.

The other main regional deposits of Toweranna and Wingina are free milling and will be able to be treated through a conventional CIL circuit.

Gravity testwork on three composite samples from Brolga achieved gold recoveries of 12.4 per cent, 27.3 per cent and 12.1 per cent as gravity testwork continues on samples from Aquila, Crow and Falcon.

Overall gold recoveries of 95 per cent have been achieved on samples from Brolga using a flowsheet combining gravity, flotation/oxidation and CIL in initial testwork to date.

“The results from our ongoing metallurgical testwork program continue to give us confidence in the multiple pathways we have to achieve high gold recoveries from Hemi and the regional deposits at Mallina,” De Grey Mining managing director Glenn Jardine said in the company’s ASX announcement.

“Each of the potential oxidation processes delivered high recoveries, with POX and Albion® the standouts respectively at 97 per cent and 98 per cent.

“Further testwork and trade off studies underway will enable us to optimise the various aspects of our metallurgical program in terms of capital, operating costs, recoveries and operability.”

De Grey Mining Lights Up Scooby and Antwerp Gold Potential

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) has been encouraged by recent drilling activity at the Greater Hemi Intrusion targets, surrounding the company’s Hemi gold discovery in Western Australia.

De Grey has been undertaking exploration within the Greater Hemi area using systematic aircore drilling, geophysical and geochemical techniques to identify mineralised intrusions based on recent experience from the Hemi discovery.

Between January 2020 and early February 2021, the company has drilled 2,135 aircore holes.

A combination of these exploration approaches is being used to identify and prioritise high prospectivity targets for follow up RC drilling at the Scooby and Antwerp targets.

The recent results include:

Scooby

Shallow gold intercepts in aircore include:

BXAC437
3 metres at 97.4 grams per tonne gold from 45m, including 1m at 264g/t gold from 45m;

BWAC630
10m at 2.1g/t gold from 48m;

BWAC635
3m at 1.5g/t gold from 48m; and

BXAC436
2m at 4.8g/t gold from 39m.

Antwerp

Results followed on from previously reported shallow gold mineralisation results, including the intersection of quartz veined and altered intrusion in limited shallow RC drilling.

New results include:

HERC146
6m at 1.4g/t gold from 62m; and

HERC146
3m at 1.1g/t gold from 96m.

De Grey considers potential exists for Antwerp to link with the recently discovered Eagle zone.

“Recent exploration activities at Scooby and Antwerp have identified widespread gold mineralisation in aircore drilling warranting follow-up RC drilling,” De Grey Mining technical director Andy Beckwith said in the company’s ASX announcement.

“This drilling will commence in the near future in parallel with resource delineation and extension drilling at Hemi, including at the recently discovered Diucon and Eagle zones.

“The new IP target coincident with gold and arsenic mineralisation at Scooby are encouraging.

“The IP results potentially provide a new tool to identify and prioritise targets beneath the transported cover.

“Diucon, Eagle and Antwerp will be our next priority IP areas.”

De Grey Mining Claims Two More Hemi Gold Discoveries

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) appears to have done it again with the claiming of two new gold discoveries at the company’s Hemi gold project located south of Port Hedland in Western Australia.

De Grey Mining announced the discovery of two new mineralised intrusions immediately west of Crow, at Hemi.

The new discoveries, Diucon and Eagle, are located immediately west of Crow along the SW-NE trending structural corridor running from Scooby to Antwerp.

Recent aircore and RC drilling defined two new zones of gold mineralisation over approximately one kilometre and 500 metres of strike respectively.

The company noted the intrusions are not highlighted by any magnetic signature, which it said leaves large scope to define further non-magnetic intrusions throughout the region.

Gold mineralisation was intersected in first pass aircore and RC drilling, including:

Diucon intrusion initial RC drill results include:

HERC382
99 metres at 1 gram per tonne gold from 114m (at a 0.3g/t lower cutoff), including 19m at 2g/t gold from 158m, 6m at 4.5g/t gold from 186m and 9m at 1.3g/t gold from 204m; and

HERC435
29m at 1.1g/t gold from 55m in (at a 0.3g/t low cutoff) including 10m at 2.6g/t gold from 74m

An encouraging gold zone was identified in aircore drilling over approximately 1km in strike and 300m wide.

The strongest gold mineralisation appeared at the western end from 40m to 200m depth and remains open to the west and at depth with further RC drilling underway.

Eagle intrusion results from the first two RC holes at Eagle include:

HERC377
68m at 0.7g/t gold from 50m (at a 0.3g/t lower cutoff), including 3m at 1.3g/t gold from 51m and 6m at 2g/t gold from 78m and 18m at 1.3g/t gold from 96m.

“Systematic aircore drilling around Hemi has discovered two new mineralised intrusions: Diucon and Eagle,” De Grey Mining managing director Glenn Jardine said in the company’s ASX announcement.

“The initial follow up RC drilling has intersected broad zones of shallow gold mineralisation.

“Wide spaced drilling is at an early stage and both intrusions remain open along strike and at depth.

“Follow up RC drilling will continue with the aim to delineate the extent and continuity of gold mineralisation in both intrusions.

“Potential exists to define new resources to add to the existing gold endowment at Hemi.

“Systematic aircore drilling continues in the Greater Hemi area.”

HERC421
67m at 1.6g/t gold from 119m – within an overall interval of 93m at 1.2g/t gold from 110m

HERC402D
66.7m at 1.4g/t gold from 198.3m – within an overall interval of 145.7m at 0.9g/t gold from 198.3m. Visible gold was previously reported in HERC402D

HERC425
25m at 2.1g/t gold from 268m – within an overall interval of 90m at 1g/t gold from 210m – The hole ended in a mineralised horizon – a diamond tail follow-up is planned.

HERC299DW1
20.9m at 1.9g/t gold from 369m – within an overall interval of 133.4m at 0.7g/t gold from 256.5m − Mineralisation tested to approximately 350 vertical metres and remains open at depth.

HERC426
6m at 5.9g/t gold from 99m.

De Grey Mining managing director Glenn Jardine said in the company’s ASX announcement.
“The latest results at Falcon demonstrate the consistently high gold endowment of this zone along a strike of 1,000 metres and to a depth of at least 350 metres.

“Mineralisation remains open down dip, along this strike and up dip on some sections.

“Drilling will continue to expand the mineralisation at Falcon to define a resource in mid-2021.

“The company has recommenced its drilling program with eight drill rigs operating on site – two aircore rigs, three RC rigs and three diamond rigs.

“As well as delineating the existing zones at Hemi, aircore and RC drilling is progressively expanding to known and new intrusive targets in the Greater Hemi area.

De Grey Mining Hits Depth Extensions and Visible Gold at Falcon

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

De Grey Mining carried out aircore drilling at the new Falcon intrusion, located approximately 600 metres west of the Brolga deposit and immediately south of the Aquila deposit.

The drilling encountered a broad mineralised zone extending from 800m to more than 1,000m along strike and 300m below surface at Falcon.

Results include:

HERC296
31 metres at 3.3 grams per tonne gold from 101m.

Tis intersection was achieved 50m downdip of a previous intersection of 50m at 3.3g/t gold from 50m in HERC265.

Mineralisation is interpreted to remain open across strike and down dip.

Elsewhere 42m of sulphide altered intrusion containing visible gold was intersected in HERC402D, extending mineralisation 50m – 100m below a previous intersection of 25m at 2.2g/t gold from 124m in HERC256.

Mineralisation is open down dip of HERC402D and up dip of HERC256.

Other intersections encountered along the mineralised zone include:

HERC414
74m at 0.9g/t gold from 88m and 31m at 1.3g/t gold from 209m; and

HERC412
32m at 2.4g/t gold from 43m and 8m at 5.5g/t gold from 99m.

De Grey claimed the intrusion to be now defined by aircore drilling over approximately three kilometres in strike.

Strong mineralisation has been defined over a strike length of approximately 1km with bedrock mineralisation covered by approximately 30m to 40m of transported material, similar to the Aquila, Brolga and Crow deposits.

“Falcon was identified as a separate intrusion zone at Hemi in September,” De Grey Mining managing director Glenn Jardine said in the company’s ASX announcement.

“The company has been following up the initial positive shallow aircore drill results with infill and extensional RC and diamond drilling.

“The latest results demonstrate the gold endowment of this zone along a strike of 1,000 metres and to a depth of at least 300 metres.

“Mineralisation remains open down dip, along this strike and up dip on some sections.

“Falcon has the potential to provide an important contribution to the overall gold endowment at Hemi.

“Extensional RC and diamond drilling will remain a focus at Falcon.

“The company has seven drill rigs operating on site; two aircore rigs, three RC rigs and two diamond rigs.

“A third diamond rig is being mobilised and is expected to commence by early December.

“As well as delineating the existing zones at Hemi, aircore and RC drilling is now progressively expanding to known and new intrusive targets in the Greater Hemi area.”

De Grey Mining Extends Crow and Aquila Mineralisation

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) reported on drilling recently carried out at the company’s Hemi gold discovery, located south of Port Hedland in Western Australia.

De Grey Mining has been drilling on the Aquila and Crow zones that are located adjacent and to the north of the large Brolga intrusion at Hemi.

The company is continuing with extensional step out drilling in these two zones on a nominal 80m by 80m spacing to the northwest while infill resource definition drilling to a 40m by 80m spacing is continuing in the central and eastern portions of Crow.

Step out and infill drilling at Hemi is on-going and the latest results at Aquila and Crow continue to firm up areas of high-grade gold mineralisation (+2g/t) within a much larger and broader gold system.

High-grade gold was intersected at the eastern edge of Crow with mineralisation remaining open to the east.

Results on section 30520E include:

HERC342
17 metres at 12.9 grams per tonne gold from 91m, including 7m at 29.4g/t gold from 94m;

HERC343
5m at 7.4g/t gold from 139m, including 3m at 11.6g/t gold from 141m; and

HERC350
15m at 1.8g/t gold from 79m.

Depth and strike extensions were encountered at the southwestern portion of Crow where mineralisation remains open along strike and up and down dip.

Results on section 30080E include:

HERC246D
24.6m at 1.4g/t gold from 345m.

New results from Aquila extended mineralisation at depth and to the southwest, again mineralisation remains open.

Results include:

Section 30080E

HERC246D
24.6m at 2.7g/t gold from 244.36m, including 5m at 5g/t gold from 252m; and

Section 29920E

HEDD010
35.6m at 1g/t gold from 419m.

“The new results at Crow continue to demonstrate potential for higher grade lodes within the large, broad mineralised zones,” De Grey Mining managing director Glenn Jardine said in the company’s ASX announcement.

“The company recently announced extensions to the northwest of Crow.

“Potential also remains for extensions to the northeast and southwest.

“Wide spaced 80 by 80 metres extensional RC drilling continues in the northwest of Crow, with assay results awaited.

“Aircore drilling further to the west of the Crow intrusive has identified areas for follow up RC drilling.

“Drilling will continue at Crow to infill and expand the mineralised footprint.

“Drilling at the western end of Aquila continues and has extended mineralisation at depth and to the west toward Falcon.

“A broad mineralised zone is present at least 400 metres below surface that includes narrower high-grade intervals.

“Total metres drilled at Hemi now exceed 200,000 metres since the discovery in December 2019.

“Seven rigs are currently operating around Hemi in support of completion of a maiden resource by the middle of 2021.”

De Grey Mining Achieves High-Grade Gold Recoveries at Hemi

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) reported results from initial metallurgical testwork from the company’s Hemi gold deposit, located south of Port Hedland in Western Australia.

De Grey Mining undertook initial metallurgical testwork on mineralisation from the Brolga Zone, which achieved excellent gold recoveries of:

Oxide: 93 per cent based on CIL leach; and
Fresh: 96.3 per cent based on sulphide flotation, oxidation and CIL leach.

The company explained the testwork flowsheet comprised a conventional carbon in leach (CIL) circuit to treat oxide mineralisation.

“The gold recovery achieved in the initial metallurgical testwork of oxide, transition and fresh mineralisation at Brolga is very encouraging,” De Grey Mining managing director Glenn Jardine said in the company’s announcement to the Australian Securities Exchange.

“The testwork significantly de-risks the potential development of Hemi as a Tier 1 gold project in a Tier 1 jurisdiction.

“The testwork flowsheet used for Hemi can also be applied to De Grey’s other regional resources in the Mallina Basin.

“Hemi is a growing resource and contains a combination of oxide, transitional and fresh sulphide mineralisation.

“We will continue to increase our understanding of the scale and metallurgical properties of each of these domains across the deposit with ongoing testwork.

“Hemi’s excellent location, along a major transport, gas and power corridors, all within 60 kilometres of Port Hedland, is a major advantage for a Tier 1 gold resource and development project.”

The flotation circuit generated a gold-rich sulphide concentrate that was oxidised using pressure oxidation (POX) that represented approximately 10 per cent of the ore feed to the flotation circuit.

Oxidised flotation concentrate from the POX circuit was treated by CIL to recover gold.

The company indicated it would assess other methods of oxidation during ongoing test work.
