De Grey Mining visible gold

De Grey intersects strong gold mineralisation at Crow and Aquila

De Grey Mining Limited (ASX: DEG) has reported continued success from the drilling at Hemi gold discovery in Western Australia, intersecting visible gold in the McLeod lode at Crow zone, and strong mineralisation within the existing mineralised footprint at Aquila zone.

DEG reported that HERC660DW1 in the McLeod lode at Crow returned 25.0m @ 12.1g/t Au from 164m including 6.0m @ 44.9g/t Au from 178m.

Significant new intercepts from Aquila zone included 11m @ 10.5g/t Au from 51m including 1m @ 105.5g/t Au.

Drilling at Hemi

De Grey reported that the resource definition drilling at Crow and Aquila zones within the Hemi discovery has intersected strong gold mineralisation.

The Aquila and Crow zones are located to the north of the large Brolga intrusion at Hemi. The Aquila and Crow mineralised systems are approximately 1000m E-W, 600m N-S, at least 500m in depth and remains open.

Visible gold intersected at Crow

DEG reported that visible gold was intersected again in the McLeod lode at the Crow zone. The company said that drill hole HERC660DW1 in the McLeod lode at Crow returned 25.0m @ 12.1g/t Au from 164m including 6.0m @ 44.9g/t Au from 178m; and 48.7m @ 2.8g/t Au from 195m including 6m @ 9.3g/t Au from 201m and 7.3m @ 5.4g/t Au from 231m.

This new result is 120m along strike to the east from the previously reported 64m @ 13.4g/t Au from 141m in HERC238 including 19m @ 42.0g/t Au from 170m.

Additional significant new resource definition drilling results at Crow included 18m @ 13.5g/t Au from 179m including 6m @ 38.9g/t Au from 180m in HERC664 (McCleod Lode); 11.8m @ 6.7g/t Au from 294.3m including 4.7m @ 13.7g/t Au from 300.8m in HERC625D; 14m @ 3.8g/t Au from 175m including 1m @ 41.0g/t Au from 187m in HERC568; 11.8m @ 3.3g/t Au from 312m including 2.1m @ 14.6g/t Au from 318m in HERC314D; and 26m @ 2.6g/t Au from 56m including 5m @ 8.7g/t Au from 73m and 13m @ 2.4g/t Au from 112m in HERC661.

Significant near surface extensional drilling results in the north of Crow included 62m @ 0.9g/t Au from 25m including 4m @ 3.1g/t Au from 26m in HERC544.

Strong mineralisation at Aquila

DEG said that the recent resource definition drilling at the Aquila zone intersected strong mineralisation within the existing mineralised footprint.

Significant new intercepts included 11m @ 10.5g/t Au from 51m including 1m @ 105.5g/t Au in HERC542D; 44m @ 2.0g/t Au from 48m including 4m @ 6.4g/t Au in HERC650; and 57m @ 1.4g/t Au from 117m in HERC562.

What’s next?

DEG said that further work would include follow-up aircore drilling to test for strike extensions to mineralisation. The company said that programs of follow up RC and diamond drilling aimed at extending resources at depth and laterally are underway.

Management comments

De Grey General Manager Exploration, Phil Tornatora, said: “Aquila-Crow is one of the more structurally complex areas at Hemi and has significant gold endowment. The McCleod Lode at Crow has now produced a number of thick, very high-grade intersections which add significantly to the resource potential.

Improved targeting of these high-grade zones is ongoing as we gain a better understanding of the geological controls. Aquila continues to produce consistent, wide gold intersections throughout the lode, particularly in shallower portions.”
