Monday, November 11th, 2019
The drilling is planned to extend the current shallow resources along strike and down dip of the main 3-kilometre resource area.

De Grey Mining Ltd (ASX:DEG) has revealed significant gold results from follow-up reverse circulation (RC) and aircore drilling at the Mallina area within its Pilbara Gold Project in Western Australia.
The drilling targeting immediate extensions of the recent and previously released shallow high grade aircore intersections returned results including:
- 3 metres at 7.9 g/t gold from 27 metres in MLRC282;
- 10 metres at 3.1 g/t gold from 53 metres in MLRC288 including 4 metres at 6.7 g/t gold from 56 metres; and
- 10 metres at 2.8 g/t gold from 77 metres in MLRC282 including 3 metres at 7.4 g/t gold from 83 metres.

Mallina has a resource of 3.83 million tonnes at 1.3 g/t for 160,700 ounces based on drilling to July 2018.
Subsequent drilling has provided a substantial number of intersections outside the existing resource model.
The planned drilling program has now been escalated and bought forward in order to rapidly assess this greater potential.

De Grey technical director Andy Beckwith said: “Mallina drilling results have culminated in an escalation of our follow-up drilling plans with a larger and more comprehensive program of RC, diamond and aircore based on these encouraging new results and the improved geological control has commenced.
“The program is planned to extend the current shallow resources along strike and down dip along the main 3km of resource area with deeper fences of RC drilling also targeting resource extensions to 200m depth initially at the Central Zone.
“We continue to await many results over our two other priority areas Withnell and Toweranna and expect to provide updates during November.”
