The geology of the prospect includes weathered metamorphic and intrusive rocks, with quartz veining and banded ron formation outcrops. The greenstones are tightly folded, and cut by late intrusive dolerite dykes. Gold mineralisation at Andy Well is associated with ultramafic and felsic porphyry’s and altered mafic schists.

The area has been subject to some historic drilling, with the last work carried out in 2000 prior to DRM's recent campaign. Historic intersections include 10m @ 7.2g/t Au and 19m @ 2.86 g/t Au. Only around 12% of the prior drill holes were completed to more than 100m in total depth, with only shallow drilling conducted in the southern half of the prospect. DRM believed there was potential to outline a significant gold deposit due to the widely space drilling and extensive distribution of mineralisation across 2km of strike length and over 200m in width.

Operator ceasing open pit mining in the second half of 2016 and transitioning to a purely underground operation.

FY2016 saw the continuation of the “modified Avoca” mining method as the primary technique being used at Andy Well. Since the introduction of this mining method, a reduction in the average mining width being achieved has resulted in reported mine grades above the latest published Reserve grade. While the 30 June 2015 Resource and Reserve Statement Reserve assumed an average mining width of 3 meters, mining widths have been further improved across both Wilber and Judy with some stopes reducing to 1.5m wide. The continuing success of this method of ground stabilisation and control is planned to be deployed for all future mining underground at Andy Well.
