Mosquito Creek
(100% Interest)
- Covers 70km2 of the Nullagine goldfield prospective for shear hosted gold deposits in Archaean age metasediments structurally deformed and intruded by porphyritic rocks.
- Extensive gold geochemical anomalies, historic workings and placer deposit targets warrant further exploration for significant gold deposits.
The Mosquito Creek Project is located in the east Pilbara region of Western Australia, some 40 kilometres east of Nullagine which is in turn 190 kilometres north from the regional centre of Newman. Talga Gold Ltd owns the right to purchase 100% of the project claims comprising two exploration licences and seven prospecting licences.
The project licenses cover a host of gold targets located in the Archaean aged Mosquito Creek formation, a 5+ kilometre thick sequence of metamorphiosed and interbedded conglomerate, sandstone, silstone and shale that is part of the Nullagine Group of the De Grey Supergroup.
The project hosts orogenic style lode-gold deposit targets where structurally emplaced quartz veins along shear zones and faults can develop both high grade/low tonnage or large tonnage/low grade gold resources. This is demonstrated by production and resources of adjacent deposits reported by other companies such as 0.167Mt @ 21.4 g/t Au for 190,335oz Au at the Blue Spec/Golden Spec system to the west of the project and 2.43Mt @ 2.12 g/t Au for 165,579oz Au at the adjacent Golden Gate deposit.

In addition the outcropping gold mineralisation of the Middle Creek area has been shedding into the project area, forming sizeable dryland channel deposits that have produced sporadically on a large scale since the 1980’s. The project area contains 15 km total length of channel deposits with an average width of over 100m and depth of 3m determined from historical ground surveys and modern aerial photography and Landsat imagery. The attraction of channel gold deposit is their shallow depth, free digging character and low cost treatment. This provides a potentially cheap, rapid path to gold production. Work by Harmanis, Gabriel Resources and others have produced various historical estimates of significant tonnage and grade in the project tenements. However further bulk sampling is required to verify the potential and prove to modern standards.
Plan & Timeframe
The project tenements are expected to be granted during the middle of 2010 making them available for testing. Once granted Talga plans to commence work on the hardrock and channel deposits concurrently. At Mosquito Creek the geological target of Orogenic lode-style gold deposits similar to Golden Eagle will be developed by geochemical surveys to assist with geological interpretation and optimum siting of drillholes. Assessment of the channel placer deposits will take place with a bulk sampling program involving onsite treatment of potential ore zones, or trucking of samples up to the Talga Talga project for processing.
