JUNIOR explorer Aldoro Resources (ASX: ARN) has commenced the maiden drilling at the Penny South project in the Murchison region of WA.

This preliminary 5000m aircore campaign will test the magnetic corridor, which has been interpreted as the strike extension of the Penny West Shear by Aldoro’s recent targeting work, which identified seven areas over a 2.5km strike extension of magnetic low greenstone and granodiorite assemblage.

The program at Penny South will consist of about 100 holes at 100m x 25m spacing along 2km of strike, with sample analysis for gold and multi-element geochemistry for pathfinder elements known to be associated with mineralisation at the neighbouring Penny West and Penny North deposits.

Aldoro managing director Caedmon Marriot said that the company was excited to move ahead with the maiden campaign at Penny South.

“The first program aims to test two things,” he said.

“Firstly, for shallow mineralisation in this target corridor that hasn’t adequately been tested by historic drilling and secondly, for combinations of gold and pathfinder elements, lithology and alteration as indications of potential deeper mineralisation to be tested in the subsequent follow up program.”

The adjacent Penny West was known as a “blind discovery”, as there were no old workings on top of the mine, which was unusual considering the regions rich mining history.

Penny West was first drilled in the late 1980s, with an intersection of low-grade gold at up to 1.5g/t, however the follow up drilling results in 1990 peaked at 339g/t.

Penny West was mined for 150,000oz at a massive average of 22g/t.
