Mineral exploration and development firm Greatland Gold has commenced drilling at its Lisle project in north-east Tasmania.

The project covers approximately 70 square kilometers of rocks prospective for gold mineralization.

The company said that the Lisle goldfield is reputed to have produced 250,000 ounces of gold from alluvial workings, and the area has been only patchily explored by various firms since the early 1970s.

The bedrock source of the alluvial gold remains open to speculation, however the company has defined several targets that have potential to host lode or disseminated gold deposits.

The bedrock targets are under shallow cover and Greatland Gold believes that any mineralization located would be readily open pittable.

Greatland Gold has received all necessary government approvals for an open hole percussion drilling program within the Lisle tenement.

According to the company, the current drill program will test four target areas over a strike length of about 2.2 kms, and will also examine the nature and extent of cover at Lisle.
