The Davyhurst project area contains both historical open cut and underground mining operation and is located 120 km north-west of Kalgoorlie. The Davyhurst area hosts some of the largest deposits within the project area and considerable potential remains for the discovery of new gold deposits as well as extensions to existing resources.
GEOLOGY & MINERALISATION
Mineralisation at Davyhurst occurs along two principal trends; On the eastern side of the project area mineralisation is developed in a series of silica biotite pyrite altered shears within a tholeiitic to Hi MgO basalt sequence.
At Lights of Israel an ore shoot within the shear has been tracked with drilling for approximately 1.8 km down plunge and mined to approximately 500 m below the surface. The deposit remains open at depth. Conceptual repeat target exists in the footwall of the LOI deposit.
The company believes similar shoot development could occur in the adjacent Maiki and Great Ophir deposits.
The company also believes it has identified the possible northern extension of the Golden Eagle ore shoot down plunge from an existing open cut.
On the western side of the project, the Waihi tend extends some 30 km from Two Gum Dam prospect in the south, to north of the Waihi Open cut. Gold mineralisation is associated with the sheared contact between a tremolite chlorite schist and Hi MgO basalt unit. Along the trend there are a number of advanced targets that require additional drill testing.
RESOURCES & RESERVES
The last JORC (2004) resource estimate for the project was compiled in 2008 based on past ASX releases and reports. The estimated was released in the Swan Gold Mining Limited 2013 prospectus released 13th February 2013 (Table 1).
