Results from YTC Resources' (ASX: YTC) two deepest drill holes so far at Nymagee Copper Mine have extended the high grade copper mineralisation to approximately 165 metres below the deepest mined levels.
The mineralisation remains open at depth. Holes NMD008 and NMD008W1 were drilled as a parent and wedge hole to test for depth extensions.
Results include:
- NMD008W1: 20 metres at 3.9% Cu, 0.20g/t Au and 22g/t Ag from 452m, including;
14m at 5.1% Cu, 0.27g/t Au and 22 g/t Ag from 458m, including;
6m at 7.8% Cu, 0.6g/t Au and 41 g/t Ag from 465m as massive sulphide.
- NMD008: 9.0m at 3.1% Cu and 19g/t Ag from 436m.
Importantly, hole NMD008W1 also intersected very significant footwall mineralisation, including a potential "blind" copper pipe structure which returned an intersection of 19m at 1.0% Cu from 361m, including 3m at 3.5% Cu from 368m.
The massive sulphide intersection in hole NMD008W1 of 6m at 7.8% Cu has recorded significant gold credits of 0.6g/t Au.
These are the highest gold values recorded by YTC within the Nymagee main lode mineralisation and may represent the development of significant gold credits associated with copper mineralisation at depth.
The continuity of the zone, together with the increasing grade at depth are very encouraging for YTC as the Nymagee deposit has the potential to be mined and treated under an expanded development scenario in conjunction with the company's Hera Project.
The project could produce significant quantities of copper in concentrate, in addition to gold, silver, lead and zinc under an integrated development.
The vertical persistence of high grade copper lodes is a key characteristic of "Cobar Style" deposits in general and of the world-class CSA copper deposit in particular.
The company continues to carry out its aggressive exploration campaign with 2 drill rigs operating at Nymagee and 2 drill rigs at the Hera Project.
