The Maggie Hays project comprises a single
granted exploration licence of E63/879 covering 105km2 in the
central parts of the Lake Johnston greenstone belt. The
tenement is located 3km south of the Maggie Hays nickel
sulphide deposit and extends for 17km to the south-southwest.
Bedrock geology of the project is largely covered by
lake sediments and aeolian sand. Interpretation of
aeromagnetic data and regional geological mapping suggests the
underlying rocks are largely granitoids, however mapping by
the Geological Survey of Western Australia (‘GSWA”) shows the
tenement covers the structurally complex western margin of the
Lake Johnston greenstone belt. This stratigraphic and
structural setting is similar to that of the Lake Percy area,
40km to the north-northwest, which has returned anomalous
nickel intercepts from reconnaissance drilling.
Between 1966 and 1994 Laporte Titanium Australia Pty
Ltd, Western United Mining Services Pty Ltd, Forrestania Gold,
and Maggie Hays Nickel NL previously held tenements that
partially overlap the current project area. Their work focused
on nickel and gold exploration, but largely in areas
immediately east of the current project area. No specific
exploration data relating to Regency’s Maggie Hays tenement
area is known apart from regional mapping and airborne
surveys.
The project area is in the early stage of
evaluation and the proposed exploration program, for nickel
sulphide mineralization, reflects this. Work proposed includes
evaluation of existing airborne geophysical datasets and
Landsat imagery to assist in identifying the extent and
complexity of the greenstone margin.
Further work will
comprise geological mapping, and soil and auger geochemical
sampling programs. Any subsequent targets would be tested with
Reverse Circulation (‘RC’) drilling.
