Mamba Exploration has unearthed gold mineralisation in most holes to-date during follow up drilling at its Calyerup Creek project, with mineralisation remaining open in all directions.
According to Mamba, significant mineralisation was hit in 13 out of 14 holes across multiple shallow zones at the project which is located in Western Australia’s Great Southern region.
Highlight intercepts were 9m at 2.5 grams per tonne gold from 6m; 5m at 1.1g/t gold from surface; and 17m at 0.65g/t gold from surface, including 5 at 1.32g/t gold from 20m.
The results are from the first 14 holes completed in 2022 with managing director Mike Dunbar noting that combined with the initial eight holes drilled last year, the company has hit “significant mineralisation” in 20 out of 22 holes.
“Importantly, we are still just scouting out the lateral extent of the mineralisation with all the drilling within the top 40m of surface,” he said. “No deep drilling is planned until we have confirmed the strike extent of the mineralisation.” The current drilling program is expected to wind up in the next week, with assays anticipated by early April.
In parallel with the shallow reverse circulation program, Mamba has completed environmental surveys. With the positive results from these surveys, Mamba expects an expanded program of work to be approved “in the coming weeks” for the next phase of drilling at the program.
This is scheduled to begin before the winter rainy period. Calyerup Creek is home to historical shallow gold workings and soil sampling at the project returned grades up to 2.8g/t.
Soil sampling has identified two 1,400m-long trends. The project comprises two exploration licences covering 45sq km and is about 12km east of the Jerramungup township.
