In March 2020, Enterprise entered into an 18 month Option Agreement with Mrs Vera Allen to purchase her Mandilla Gold Prospect (Exploration Licence 15/1437 and Prospecting Licence 15/5885) located approximately 20 km south of Kambalda. Enterprise’s target is high-grade primary gold mineralisation, similar to that already discovered on the western margin of the Mandilla Syenite by Anglo Australian Resources (“Anglo”, ASX: AAR) at its Mandilla Gold Project.
Between 2006-2007, Anglo produced ~23,000oz Au from an open cut palaeo-channel located along the western margin of the syenite. Anglo subsequently reported an Inferred bedrock resource of ~360,000t at 3.3 g/t Au [~38,000 oz Au] at Mandilla East, on the western margin of the Mandilla Syenite. (Figure 7)
In June 2020, the Department of Mines, Industry Regulation and Safety approved Enterprise’s Program of Work (PoW) for approximately 150 aircore drill holes to test the soil covered eastern margin of the Mandilla Syenite. A scout program of 121 vertical aircore holes (2,408m) was subsequently completed east of the Coolgardie-Esperance Highway in August 2020. The holes planned west of the highway could not be drilled due to heritage issues. A small passive seismic survey was also conducted, to map the depth of the Cainozoic cover sequence and weathered basement rocks.
