A new mining era for the historic Cobar Shire village of Nymagee is likely following last week’s sale by CBH Resources Ltd of its Hera gold and base-metal tenements to Chinese-backed YTC Resources.
Discovered by Pasminco in 2001, and advanced to pre-feasibility by Triako Resources from 2002 to 2006, the Hera project was acquired by CBH in a multi-million dollar 2007 take-over of Triako.
To date a total of 141 drill holes, each approximately 90 metres deep, have been completed on the deposit which is located near The Peak, 5km south of Nymagee.
Hosted in Cobar Basin rocks, the potentially rich Hera deposit represents multiple lenses of sub-vertical gold and base-metal mineralisation and extends approximately 600m along strike. Significant other mineralisation within the deposit include several additional lenses known as the far west and western lenses.
The Hera deposit, named by Triako’s geologist after an ancient Greek goddess, is typified by bonanza-grade gold zones distributed north and south of the central offset fault.
In addition, a 4.5km corridor of strike between the Hera and Nymagee deposits represents highly prospective stratigraphy with relatively light previous exploration and shallow drilling.
The outstanding exploration potential of the Hera deposit is best demonstrated by the deepest drill hole completed by Triako in 2006.
The hole recorded an intersection of 7.8m @ 15.3g/t Au (uncut), 7.5 per cent Pb, 12.5 per cent Zn, 42g/t Ag from 629.4m.
New owners YTC are confident that Hera, the Nymagee mine and the 4.5km intervening corridor represent very high prospectivity for resource extension, additional lens discovery and the potential for a large Cobar style gold-base metal system.
Nymagee’s previous mining period extended from 1880 to 1917 during which more than 400,000 tonnes of copper ore grading 5.8 per cent CU was produced.
