THE DRILL SERGEANT: De Grey Mining (ASX: DEG) reported on recent drilling activities undertaken at the Brolga Zone, situated within the company’s Hemi gold discovery near Port Hedland in Western Australia.
De Grey Mining claimed aircore drilling aon the Brolhga Zone has defined a major extension, measuring approx. 1000 metres long by 200 metres, wide of the Brolga intrusion.
The company said the results achieved by the drilling to have enhanced potential to expand near surface open pit resources.
Results of initial shallow aircore holes include:
16 metres at 2.4 grams per tonne gold from 40m;
8m at 2.2g/t gold from 52m; and
4m at 5g/t gold from 60m.
Of note, the company is still to receive around 90 per cent of results from the new shallow aircore at Brolga.
Additional RC and diamond achieved results at Brolga include:
55.3m at 1.9g/t gold from 184.7m;
6.13m at 4.8g/t gold from 220m;
18.21m at 1.5g/t gold from 254.79m;
2m at 10g/t gold from 161m; and
16m at 1.4g/t gold from 177m.
“Hemi continues to demonstrate potential to be a large scale, world class deposit and the project area continues to demonstrate its prospectivity for further discoveries,” De Grey Mining newly-appointed managing director Glenn Jardine said I n the company’s announcement to the Australian Securities Exchange.
“It has been a sharp learning curve at Hemi for the exploration team and this new discovery is a credit to their targeting from that learning.
“The new discovery appears to be analogous to the early stages of the initial Brolga discovery.
“We see a lot more value still to come for investors in De Grey.
“With this in mind, we are increasing our drilling effort from four rigs to six rigs during June.
“The focus of drilling will continue to be on defining the extent of known mineralisation at Hemi and new discoveries moving into the many regional intrusion and shear zone targets.
“To complement the scale and extent of near surface mineralisation at Hemi, the project is blessed with world class infrastructure.
“Everything that we need is on our doorstep including high voltage power, gas pipelines and major highways all within 25 kilometres of the project area and an hour drive from Port Hedland, a major transport and services hub.
“We are also highly encouraged to continue our early stage environmental, infrastructure and metallurgical studies.”
De Grey Mining has Hemi shaping up as a world class, large scale deposit where the company is continuing to drill in order to determine the extent of the Hemi mineralisation with the expectation that overall project resources will increase from the current 2.2 million ounces.
The company said it has at least four other look-alike intrusion targets already defined in the immediate region surrounding Hemi, three of which have known ore grade mineralisation.
A detailed airborne magnetic survey was recently completed and will be used to further improve and enhance targeting.
