What is open-pit mining?

Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth. Open-pits are sometimes called ‘quarries’ when they produce building materials and dimension stone- The majority of the project remains effectively untested with limited drill testing. Identification and development of relatively low capex, near surface mineralisation has the potential to provide early cash flow.

These gold mineralised systems have had limited drilling and the project remains ineffectively tested. The scale of the strike extensive gold anomalism associated with this gold mineralising system and grade of the known gold deposits is encouraging.
Although previous explorers recommended further work in the areas encompassing the Maitland North, Maitland and Maitland South workings, little follow-up work has ever been undertaken. Systematic methodological exploration to effectively and conclusively test both these gold mining centres and potential repetitions along strike is warranted.
