De Grey Mining Extends Brolga Gold Mineralisation

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) released further results from drilling on the Brolga Zone within the company’s Hemi gold discovery, located near Port Hedland in Western Australia.

New RC gold intercepts encountered at Brolga include:

HERC014
78 metres at 1.8 grams per tonne gold from 40m;

HERC015
72m at 1.6g/t gold from 105m;

HERC016
21m at 3.6g/t gold from 45m
15m at 5.5g/t gold from 75m;

HERC017
33m at 1.6g/t gold from 41m;

HERC023
76m at 1.5g/t gold from 42m; and

HERC024
56m at 1.1g/t gold from 93m.

De Grey Mining has now defined strong and extensive gold mineralisation across four sections, demonstrating a robust and large growing volume of mineralised intrusive at Brolga.

The gold-sulphide mineralisation is well defined by the RC drilling, which the company has interpreted to be dipping moderately to the south (local grid) with a large footprint over more than 340 metres of strike, up to more than 300m lateral width, up to 200m depth that remains open along strike and down dip.

The company considers the shallower dipping mineralisation important, believing it has the potential to increase ounces per vertical metre within a future open pit and may reduce the overall strip ratio.

“Brolga is growing substantially, we continue to increase the overall footprint of the gold-sulphide mineralisation, particularly to the west and down dip where substantial thicknesses of mineralisation remain open,” De Grey Mining technical director Andy Beckwith said in the company’s announcement to the Australian Securities Exchange.

“We have now confirmed the strong correlation between gold and sulphides.

“The recent four RC holes to the south and west have logged some of the strongest sulphide mineralisation noted to date.

“Drilling is planned to continue with one RC and two diamond rigs testing the limits of mineralisation at Hemi.”

De Grey Mining Continues Hemi Gold Discovery Growth

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) produced further results from the Brolga and Aquila Zones within the Hemi gold discovery, located within the company’s Pilbara gold project in Western Australia.

De Grey Mining has identified extensive sulphide mineralisation from RC and diamond drilling over 240 metres of strike length and has demonstrated additional strike potential from encouraging aircore gold results and observations along strike over approximately 600m.

The overall scale of the Brolga Zone remains open in all directions that is currently defined only by RC and diamond drilling.

The dimensions of the Brolga Zone currently stand at 240m strike by up to 200m wide by 220m below surface and remains open.

De Grey said RC drilling undertaken on section 30,640E had confirmed substantial thicknesses of gold mineralisation associated with the extensive sulphide rich mineralisation.

RC gold results on Section 30,640E include:

HEDD002
43 metres at 1.9 grams per tonne gold from 99m, including 6m at 4.3g/t gold and 4m at 5g/t gold;

36m at 3.2g/t gold from 156m, including 14m at 5.6g/t gold; and

43m at 1.9g/t gold from 34m, including 6m at 6.9g/t gold.

Drilling at the Aquila Zone has demonstrated gold potential over 800m strike, up to 50m thick and 180m depth and remains open.

RC drilling results confirm healthy gold mineralisation, including:

HERC005
51m at 2.1g/t gold from 108m, including 8m at 4.9g/t gold;

HERC006
62m at 1.4g/t gold from 59m; and

HERC009
20m at 2g/t gold from 142m, including 3m at 6.8g/t gold.

“Brolga and Aquila are developing into two very large gold systems with widths of gold mineralisation never seen before in the project area nor the Pilbara region,” De Grey Mining technical director Andy Beckwith said in the company’s announcement to the Australian Securities Exchange.

“The ongoing RC and diamond drilling program aims to scope the overall scale of the mineralisation on 80m spaced sections.

“The large anomalous gold area to the north of Aquila is now our focus for aircore drilling.

“Anomalous gold occurs in every hole above the interpreted intrusion in earlier wide spaced aircore drilling and provides scope for further new parallel discoveries.”

De Grey Mining Encounters Continued Sulphide Mineralisation at Hemi Discovery

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) reported new drilling assay results from the Brolga Zone within the company’s Hemi gold discovery, located near Port Hedland in Western Australia.

De Grey Mining said the recent drilling had encountered further encouraging sulphide mineralisation observed over large widths and depths.

The company carried out RC drilling on sections 30,560E and 30,720E, respectively located 80m east and 80m west of the original discovery section 30,640E.

The drilling has encountered similar sulphide rich mineralisation on both sections over substantial intervals while defining extensive sulphide mineralisation over 160 metres of strike length.

The company believes the latest gold intercepts continue to extend gold mineralisation on the discovery section 30,640E.

Latest results include:

HEDD001
13 metres at 1.9 grams per tonne gold from 36m (RC pre-collar only)

HEDD001
18m at 2.3g/t gold from 59m (RC pre-collar only)

HEDD001
16m at 2.6g/t gold from 104m in (RC pre-collar only)

“Step out drilling has confirmed immediate strike extensions of the Brolga Zone, providing encouraging indications for substantial potential along strike,” De Grey Mining technical director Andy Beckwith said in the company’s announcement to the Australian Securities Exchange.

“The widths, grades and consistency of mineralisation intersected to date are very pleasing.

“Our geological model is evolving rapidly, and our confidence continues to grow that the strong sulphide rich mineralisation directly relates to gold.

“We have a large volume of assays in the lab and are continuing drilling with three rigs.

“We expect frequent news flow over the coming weeks as we progress drilling on this exciting new discovery.”

De Grey Mining Confirms Large Scale Gold System at Hemi

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) has continued to produce positive gold assay results from RC and aircore drilling programs underway at the recently discovered Hemi prospect within the company’s Pilbara gold project in Western Australia.

De Grey Mining’s recent RC and aircore drilling efforts have defined sulphide alteration along strike, over increased widths and down dip on generally wide-spaced sections between 80 to 160 metres apart.

The latest results have emerged from initial RC drilling at the Brolga Zone (Section B) and the newly named Aquila Zone (Section A and extensions), together with additional aircore results.

RC drilling results from the Brolga Zone have confirmed strong gold mineralisation at depth including:

HERC001
93 metres at 3.3 grams per tonne gold from 39m, including 21m at 4.7g/t gold;

De Grey said this result confirmed broad gold zone at depth that correlates with previous shallow aircore gold results achieved directly above.

HERC002
51m at 2.2g/t gold from 98m, including 8m at 4.1g/t gold.

De Grey said the drilling had expanded the sulphide zone expanded to over 200m wide demonstrating potential for over 320m of strike.

Drilling at the Aquila Zone has defined a northeast trend over 750m strike and up to 50m wide with results including:

HERC003
11m at 3g/t gold from 193m finishing in high-grade mineralisation of 4m+ at 6.5g/t gold;

HERC004
38m at 3.4g/t gold from 55m, including 9m at 7.4g/t gold; 50m to the north east

BWAC397
42m+ at 2.7g/t gold from 96m, including 4m at 4.2g/t gold; 480m along strike to NE and also ending in mineralisation.

Mineralisation has been confirmed to 180m below surface and remains open

Further assays remain pending on both zones and diamond drilling has commenced.

“Early drilling at Hemi has produced some of the best discovery intersections that I have seen,” De Grey Mining exploration manager Phil Tornatora said in the company’s announcement to the Australian Securities exchange.

“Drilling to date, shows exceptionally wide, continuous and good grade gold mineralisation.

“Geological indications suggest that Hemi may be more of an intrusion related style of gold system rather than the more typical orogenic shear hosted style deposits of the Pilbara and other WA goldfields.

“We have three rigs on site advancing this exciting new discovery.”

The RC and aircore drilling De Grey has undertaken to date has defined two separate parallel gold zones – Aquila and Brolga, demonstrating strong gold mineralisation associated with extensive sulphide rich alteration.

It has also increased sulphide alteration to over 200m wide at the Brolga Zone while identifying a strike length greater than 750m and up to 50m true width along the Aquila Zone.

The company believes potential exists for further, multiple mineralised zones to be discovered.

De Grey Mining Extends Mineralisation at Hemi Gold Discovery

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) reported encouraging signs from drilling underway at the recent Hemi discovery at the company’s Mallina gold project in Western Australia.

De Grey Mining has observed sulphide rich alteration over large widths and depths from initial RC holes drilled on Section B at the Hemi prospect.

A further RC drill hole, completed on Section A, intersected intense sulphide mineralisation at depth beneath the 30 metres wide high-grade gold zone.

On Section B, two RC holes (HERC001 and HERC002) and a third RC precollar (HEDD001) have tested below and to the south of previously announced shallow aircore drilling results of 24 metres at 4.2 grams per tonne gold, 15m at 2.5g/t gold and 21m at 2.5g/t gold.

The company has now observed extensive sulphide mineralisation immediately below the known gold mineralisation and in new parallel sulphide zones to the south on the section, which it considers to increase the potential for mineralisation to over 160m wide to 120m below surface with sulphide zones and potential remaining open in all directions.

On Section A, a maiden RC hole drilled targeted a 50m vertical depth extension to previously reported shallow high-grade gold mineralisation of 36m at 4g/t gold, 49m at 3.7g/t gold, 44m at 5.1g/t gold, 46m at 6.6g/t gold and 24m at 7.5g/t gold.

This recent hole intersected fresh and intense sulphide mineralisation from 192m (downhole) to 204m where the drilling rods became bogged and drilling had to cease.

De Grey is now planning a diamond core extension to complete this hole.

“The significant sulphide zones beneath the high-grade gold zones on Sections A and B are very encouraging,” De Grey Mining technical director Andy Beckwith said in the company’s announcement to the Australian Securities Exchange.

“The large sulphide zones on Section B have the potential to significantly increase Hemi’s scale.

“The genetic link between Sections A and B as intrusion hosted is exciting and increases the potential at Hemi.

“This is supported by the aircore drilling results to date that highlight every hole above the interpreted intrusions are anomalous in gold.

“The aircore and RC programs are continuing, and a diamond rig is expected on site later this week.”

De Grey Mining Releases Further Hemi Hits

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) kept the good news rolling with further results from follow up aircore drilling at the newly discovered Hemi prospect within the company’s Pilbara gold project located just outside Port Hedland in Western Australia.

De Grey Mininig said the latest drill results correlate very well with previously reported gold mineralisation, confirming a substantial steeply south dipping zone of high-grade gold mineralisation.

This mineralisation is defined as 30 metres wide (apparent thickness), and extends to 130m below surface, remaining open at depth and along strike.

The weighted average grade of all results within the mineralised envelope on Section A is 5.2 grams per tonne.

New results on Section A include:

BWAC320
44 metres at 5.1 grams per tonne gold from 40m, including 13m at 8.8g/t gold; and

BWAC321
46m at 6.6g/t gold from 92m, including 21m at 8.3g/t gold;

The company indicated the above results correlate strongly with its results announced earlier this month of:

BWAC315
24m at 7.5g/t gold from 126m, including 18m at 8.6g/t gold (EOH);

BWAC309
49m at 3.7g/t gold from 65m, including 18m at 6.6g/t gold;

BWAC245
36m at 4g/t gold from 39m, including 11m at 8.9g/t gold.

“These are stunning results – high grade, thick and consistent,” De Grey Mining technical director Andy Beckwith said in the company’s announcement to the Australian Securities Exchange.

“Clearly, drilling below this zone and the mineralisation on Section B are two key high priority RC targets.

“We are looking forward to receiving the remaining aircore drilling results and re-commencing drilling activities now the cyclone has dissipated.”

De Grey Mining Achieves High Gold Recoveries with Conventional CIL Processing at Toweranna

THE BOURSE WHISPERER: De Grey Mining (ASX: DEG) announced positive results from metallurgical test work recently undertaken on samples from within the proposed Toweranna open pit resource area at the company’s Pilbara gold project in Western Australia.

De Grey Mining carried out test work to assess conventional carbon-in-leach (CIL) gold recovery from both oxidised and fresh rock.

The company indicated it had obtained high gold recoveries from all of the oxide zone samples, ranging from 92 per cent while the fresh rock samples returned results with 94.7 per cent gold recovery.

De Grey said the results indicate Toweranna mineralisation is free milling and fully amenable to convention CIL processing.

Separate samples were also tested for gravity recovery, with oxide and fresh rock samples returning recoveries of 20.8 per cent and 54.3 per cent respectively.

The company considers the high levels of gravity gold indicate that it may be possible to lift total gold recovery by installing a gravity concentrator ahead of the CIL circuit and as such will evaluate the merits of employing gravity extraction in subsequent test work.

“Toweranna continues to grow in stature with strong resource growth potential and high recovery with conventional CIL processing characteristics,” De Grey Mining technical director Andy Beckwith said in the company’s announcement to the Australian Securities Exchange.

“On-going drilling results continue to define multiple stacked lodes to at least 200 metres depth.

“Once drill assays are finalised, we will update the zero to 200 metres open pit resource and run open pit optimisations.

“We are increasingly seeing free gold in the veins in core and the high gold recovery together with the simple free milling nature is encouraging.

“Toweranna is poised as a game changer as it has the potential to rapidly increase resources and improve the PFS economics.”

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.”
