Okapi’s legacy Enmore Gold Project in New South Wales lies in the New England Fold Belt near the operating Hillgrove Gold Mine (ASX:RVR) which has produced over 730,000oz of gold.

There is significant exploration potential at Enmore, with 36 identified mineral occurrences – the majority of which are untested by deep drilling, modern geophysics or other targeting methods applied across the project. The mineralisation at Enmore generally comprises structurally controlled orogenic style gold (± antimony) mineralisation.

Okapi completed ten Reverse Circulation (RC) drillholes for 1,257m during 2021 across Sunnyside and Bora Prospects. Assay results returned significant gold values from all 10 drillholes and lead to a 1,800m diamond drilling campaign in 2022.

Historic exploration at Enmore has largely focussed on the potential for locating and developing open-cut resources.

Previous Exploration

Gold was first discovered in the Enmore area in 1876 and intermittently mined till 1940, with mining continuing today at the nearby Hillgrove Mine. Most previous exploration has targeted very shallow mineralisation, with approximately 233 holes completed prior to Okapi’s involvement. Of these, 153 holes are less than 50m in depth and only 41 holes are greater than 100m in depth.

Superior Geology

  • The main prospects on the Enmore goldfield (Bora Mine, Sherwood Mine, Sunnyside Mine) are defined by the presence of continuous lode style mineralisation over strike extents of up to 600m.
  • Getty Oil Development Company concluded that structural preparation of the fault corridors which host these known lode structures may be as extensive as 2.6km strike on the Borah Fault and 1.5km strike on the Sunnyside-Melrose Fault. There is potential for development of additional lodes within the structurally prepared fault corridors.

  • The deeper drilling at Enmore has been relatively wide-spaced and has not adequately accounted for the expected limited strike extent of high-grade shoots or their oblique orientation to the host lode structure. High gold grades associated with quartz veins and breccias are interpreted to represent dilational shoots and have been returned in several deeper holes, particularly at the Bora Mine where the peak result from drilling is 4m @ 20.6 g/t from 92m, including 1m @ 58.0 g/t (BSD5).

  • Significant, shallow mineralisation has been intersected at the Sunnyside Prospect, where gold mineralisation is present over some 400m between splays of the district-scale Sunnyside Fault. Mineralisation remains open at depth, with drillhole OSSRC06 being terminated at 174m depth, with the final 3m interval assaying 3m @ 8.86 g/t gold, including 1m @ 15.15 g/t gold from 172m.
  • The Sherwood Prospect on the Bora Fault remains the most interesting of the regional targets at Enmore. Historical diamond drillholes (DDH1-DDH4) were completed by Silver Valley Minerals in 1973 to test beneath the old workings. Only DDH1 was assayed and intersected visible gold at the brecciated and sheared quartzite/ granite contact. An assay of 56.6g/t gold from 60.8- 61.4m was returned from within a zone of low grade gold mineralisation.

Projects

Tallahassee Uranium Project

Our flagship Tallahassee Uranium Project comprises five major uranium deposits in Colorado, USA with an overall JORC Resource of 49.8Mlbs U3O8 (average grade of 540ppm).

Athabasca Basin Projects

Okapi has six exploration projects in Canada’s Athabasca Basin, best known as the world’s leading source of high-grade uranium and responsible for about 20% of the world’s uranium.

Rattler Uranium Project

Located within the recognised La Sal Uranium District in Utah, the Rattler Project is located 85km north of Energy Fuels Inc’s White Mesa Uranium/Vanadium mill in Utah – the only operating conventional uranium mill in the USA.

Maybell Uranium Project

The Maybell Uranium Project is situated in a recognised historical uranium mining district in Colorado USA, with historical production of 5.3Mlbs of U3O8 (average grade, 1,300ppm).

Enmore Gold Project

Okapi’s legacy Enmore Gold Project in New South Wales lies in the New England Fold Belt near the operating Hillgrove Gold Mine (ASX:RVR) which has produced over 730,000oz of gold.
