Thomas Creek Copper-Gold Target
Panned samples show chalcocite ± covellite (blue-grey) partly replacing chalcopyrite.
Soil anomaly includes exceptional assays up to 7.0% copper 3 g/t gold
Economic grades of primary copper-gold occurs in deeply weathered remnant thick ore shoots, several metres in width and open along strike
Historic Shallow Drilling at Thomas Creek• 8 shallow BQ sized holes completed in 1996
do not test the IP anomaly and appear have been drilled adjacent to parallel shallow high grade ore shoots.
• Broad zones of low grade Cu reported – i.e. TCD2 - 58m @ 0.08% Cu from 40m, TCD5 -15m @ 0.17% Cu from 32m.
• Significant core loss from intensely altered zones – higher copper-gold grades may not have returned sample for assay.
• Strongly altered porphyritic diorite –andesite with extensive hematite stockwork vein system (after primary sulphide?) and intense – silica - K-spar, sericite, chlorite alteration
• Drilling to 60-90m vertical depth (if no uplift)
• May still be in leached Cu depleted

Ultramafic rocks
VMS targets - Padthaway• Cambrian rocks in South
Australia are similar in age, lithology and geochemistry to those in western Tasmania
• Where these rocks outcrop base metal VMS mineralisation is abundant.
• They continue under shallow cover to the southeast, where limited historical drilling indicates the main volcanic source rocks occur
• Conductive cover has previously been an impediment to EM techniques
• New developments in EM technology (eg B-field) will allow Sherlock to generate new targets in this terrain Outcropping Cambrian rocks (purple) continue
under cover in the Padthaway region (aeromagnetic data). Red dots indicate base-metal mineralisation.

Forward ProgramThomas Creek Extend geochemical and geophysical
surveys to define extent and best areas to drill test
Padthaway Project Advance VMS targets with EM / IP geophysical surveys to drill ready status
Drill Test Thomas Creek Copper-Gold Project- Initially approx. 4 x 350m holes
Henrietta Nickel Project- Initially approx. 2 x 200m holes
Padthaway Copper-Zinc-Lead-Gold-Silver Targets- Initially approx. 10 x 200m holes
Budget $4 to $6 Million
Business Model• The current minerals investment market is
poor, but will improve quickly when it turns.
• Sherlock is a low cost operator – no office, no directors fees, no employees – all funds directly spent on advancing projects.
• JV partners and/or potential additional seed monies sought to assist funding near term pre-drill exploration.
• IPO/RTO when the market improves.
