Infill drilling has been undertaken within the Brolga stage-1 pit as a risk control exercise while exploration drilling continues across Greater Hemi and Regionally. 

De Grey’s (ASX:DEG) new infill results have returned thick mineralised intervals in the centre of the Brolga stage-1 pit within the wider Mallina Gold Project in Western Australia as part of a risk control exercise for early production.

The proposed Brolga pit comprises 1.29 million ounces at 1.3g/t gold of the overall JORC mineral resource of 9 million ounces at 1.2g/t gold.

New infill results on section 30600E include 80m at 1.6g/t from 36m, 93m at 2.2g/t from 43m, 127m at 2g/t from 35m, and 114m at 1.5g/t from 126m.

On section 30440E, results comprise 106m at 1g/t from 42m, 107m at 1.2g/t from 67m, 93m at 1.6g/t from 81m, and 73m at 1.2g/t from 144m.

Within section 30520E, results include 54m at 1.6g/t from 36m, 53m at 1.1g/t from 49m, as well as 22m at 1.9g/t from 124m, and 148m at 1g/t from 44m.

De Grey says infill drilling will continue as necessary during the pre-feasibility study (PFS) to provide confidence across the priority early production sources and to lift resource classification from JORC inferred to indicated at both Diucon and Eagle.

Drilling to continue until the end of 2021

DEG general manager of exploration Phil Tornatora said: “The recently announced scoping study of the Mallina Gold Project identified Brolga as an early production source.

“Resource infill drilling is reducing project risk associated with early production and the 40m x 40m drill spacing at Brolga is expected to provide a high level of confidence in the early production from Brolga,” he said.

Tornatora added that the Brolga resource infill drilling is scheduled to continue until the end of calendar 2021 to meet PFS requirements, with Brolga Resource extension drilling to follow.

“Exploration drilling continues across both Greater Hemi and Regional areas, including three aircore and three RC rigs currently engaged in exploration activities aimed at discovering large scale gold resources,” he said.

Looking ahead

De Grey is continuing exploration drilling in the Greater Hemi and Regional areas.

Three aircore and three RC rigs are currently engaged in exploration activities aimed at discovering large-scale gold resources.
