Adelaide Resources (ASX:ADN) has identified West Doora at the Moonta Copper Gold Project in South Australia as an iron ore copper gold prospect.
This follows modelling and evaluation of data from the historic diamond drill holes, which returned results including:
- 7.31 metres at 2.29% copper from 224.03 metres;
- 12.8 metres at 2.07% copper from 83.21 metres; and
- 12.8 metres at 1.48% copper from 85.65 metres.
Copper has been intersected as shallow as 20 metres from the surface, while intersections as deep as 400 metres occur, presenting further evidence that mineralisation can persist to significant depths in the Moonta district.
3D modelling of the historic West Doora drill data shows copper mineralisation occurs in two main zones.
The Eastern Zone is interpreted to be a series of stacked narrow lodes, while the Western Zone includes a thick mineralised body with internal zones that reach horizontal widths of up to 50 metres.
It also suggests suggests that the thick Western Zone may remain open downplunge to the west, presenting a promising exploration target.
Gold was not routinely assayed when the historic drilling was done, and the company has re-sampled four old holes with assaying for gold and other metals now underway.
West Doora is located southwest of the town of Kadina and was one of the main prospects explored under a joint venture between Western Mining Corporation and North Broken Hill.
It lies in the Wallaroo Mines Field within the Moonta–Wallaroo district which is in turn a part of the large Proterozoic Olympic Copper Gold Province.
