Our Projects

Our company has an exciting range of projects including well advanced, drill-ready targets through to conceptual green-field plays that are all 100% owned. Sherlock has exploration tenements in two regions, the world class mineral province of the Mt Read Volcanic Belt of Western Tasmania, and a large tenement holding (3758km2) over the highly prospective volcanic sequences of the upper Southeast of South Australia.

Tasmanian Projects

Western Tasmania is a world class mineral province most noted for its polymetallic Volcanic Hosted Massive Sulphide (VHMS) copper-zinc-lead-silver-gold and gold only deposits associated with the Mount Read Volcanics (MRV) with an accumulated resources of > 350 Mt of ore.The region also includes numerous tin deposits (i.e. Rension Bell, 24.54 Mt @ 1.41% Sn) associated with granite intrusions and nickel associated with ultramafic volcanism (i.e. Avebury 12.0 Mt @ 1.1% Ni)

Sherlock’s tenement holdings encompass 394km2 and cover a 38 kilometre length of the underexplored southern portion of the highly prospective Mt Read Volcanic Belt. It is the largest individual company holding of the Mt Read Belt. Our company has three advanced drill ready projects, Thomas Creek (copper-gold), Henrietta (nickel and platinum) and Hill 99 (copper zinc and gold).

South Australian Projects

The South Australian holdings span a volcano-sedimentary package under shallow cover (typically 40-80m depth to top of bedrock) where geological studies have shown strong affinities to the Mount Read Belt, and where reconnaissance drilling has identified tantalising evidence of VHMS mineralisation.

A notable example is the Sherlock Prospect which lies just off the Company’s tenement holdings and has returned narrow intervals of high grade zinc and copper mineralisation (i.e. drill hole SHR-07 - 8m @ 0.75% Cu, 0.22% Zn from 74m (Inc. 4m Cu @ 1.3%)) and displays classic VHMS rock alteration. VHMS deposits typically occur in clusters and the region has not undergone any form of modern systematic exploration for this style of deposit. The western edge of this prospective belt outcrops in the Eastern Adelaide Hills and hosts numerous historical base metal and gold occurrences and two major mines (i.e. Kanmantoo – 31.1 Mt @ 0.8% Cu, 0.2 g/t Au, 2 g/t Ag and Angus - 1.1 Mt @ 4.9% Zn, 2.0% Pb, 0.1% Cu, 23 g/t Ag, 0.3 g/t Au).

Our company’s tenements are amenable to modern geophysical surveys to see below the shallow cover and identify direct drill targets. Sherlock is at an early stage of target definition for this region.

Target Generation


A 1996 GEOTEM survey and the subsequent 2010 VTEM survey has been reprocessed by Sherlock and from this work over twenty priority 1 & 2 targets have been identified. 

Approximately half of the identified targets lie within the Mount Reid Volcanic volcano-sedimentary package, and these have potential for Volcanic Hosted Massive Sulphide (VHMS) style base metal and gold mineralisation.  The remainder lie within rocks mapped as mafic-ultramafic complexes, and these targets have potential for nickel and platinum group element (Ni-PGE) mineralisation.

Systematic ground works are planned to investigate these further to get them ready to drill test if warranted. Given the highly mineralised nature of western Tasmania the exploration potential for further discoveries is considered to be excellent.

South Australia

Studies undertaken by the South Australian Geological Survey have drawn strong comparisons between rocks in South Australia’s south east and those of the Mount Read Belt in Tasmania. However mineral exploration in the region has been limited due to the presence of shallow, but quite extensive cover. In general airborne surveys are not able to penetrate this cover material, and consequently Sherlock is planning a series of ground-based geological surveys targeting favourable structures and geological units in order to define new targets for drill testing.
