The Tas-West property is mainly underlain by augite-phyric intermediate flows of the Upper Triassic Takla Group, Inzana Lake Formation. Late Triasic to Early Jurassic syenitic to monzonitic intrusive rocks intrude to the south.

In 1999, Omni Resources Inc optioned the Tas claims and followed up with a 691.9 metre - 7 NQ diamond drill hole program on the West and Far East zones. Four of the holes were on the West zone. Omni reported that they discovered a previously unknown but significant mineralized zone on the West zone where gold was encountered in semi massive to massive pyrrhotite plus/minus pyrite plus/minus chalcopyrite veins. The best mineralized zone intersected in the 1999 drill program was from 23.29 metres to 30.78 metres in Hole TAS 99-5. The last 4.36 metres of this zone assayed 8.47 grams per tonne gold; in addition significant values of approximately 2.47 grams (0.077 ounces) per tonne gold were assayed over the first 2.03 metres starting at 23.29 metres down hole (Assessment Report 26185).

Navasota optioned the nearby Tas property from Derry Halleran and proceeded to drill 7 holes in 2002 to test the West zone and a strong gold geochemical anomaly. Drill holes that tested the gold geochemical anomaly encountered a swarm of plagioclase porphyry dykes and intrusion breccia locally carrying disseminated to semi-massive and massive pyrite, pyrrhotite, lesser chalcopyrite and traces of arsenopyrite. Hole TS-066 cut 12.45 metres of semi-massive to massive pyrrhotite-pyrite-chalcopyrite grading 2.3 grams per tonne gold and 0.23 per cent copper (Assessment Report 27152).
