Exploration on the tenements surrounding the Twin Hills Mining Lease is concentrating on locating replications of the Twin Hills silver mineralisation. The current Inferred Resource is 35M oz silver at Twin Hills and Mount Gunyan. The potential resource could well be in excess of 100M oz of silver.

Exploration at Texas has a two-fold aim:

• Finding more ore within the Mining Lease to extend the Twin Hills mine life.
• Finding replication of the Twin Hills silver system elsewhere in the Texas District.

Twin Hills silver mineralisation is hosted in silicified, brittle rock which is not obviously mineralised. Surface outcrop is unobtrusive and surface silver values in soil and stream sediments are relatively low. As a result the mineralisation was passed over by prospectors and not recognised as a major silver system by past explorers.
Important criteria for assessing exploration potential in the Texas District include:

• Silver soil, rock and stream sediment geochemistry
• Lead/zinc soil geochemistry
• Gold soil geochemistry
• Silica/potassic alteration
• Potassic radiometric anomalies

Silicification and potassium feldspar alteration (silica/potassic alteration) form an extensive halo around the Twin Hills mineralisation. This style of alteration indicates general silver mineralisation, but is only a guide to the presence of silver ore.

Silica/potassic alteration can be detected by an airborne radiometric survey. The silica/potassic alteration shows up as potassium radiometric anomalies. Well defined potassium radiometric anomalies are present over the Twin Hills and Mount Gunyan silver systems and in several other areas in the Texas District. The widespread potassium radiometric anomalism suggests that silica/potassic alteration is more widespread than previously thought and certainly more widespread than indicated by the soil geochemical surveys completed to date. This favours the likely discovery of further significant silver mineralisation in addition to the Twin Hills and Mount Gunyan systems.

Potential to replicate Twin Hills in the Texas District
Outside the Twin Hills area there are at least 12 other areas with encouraging geochemical and geophysical signatures. An airborne radiometric survey has defined several potassium radiometric anomalies totalling 7 sq km which have similar potassium signatures to the known mineralisation within 6 km of Twin Hills. The Twin Hills anomaly covers 1.4 sq km.  Any or all of these areas could yield additional silver mineralisation/deposits with further exploration.
