Split Rocks Lithium, Cobalt & Gold, WA (ZNC 100%)

Zenith’s Split Rocks exploration licences are located approximately 10km northwest of Kidman Resources Limited (ASX:KDR) Earl Grey lithium pegmatite deposit containing 128Mt @ 1.44% Li2O (KDR ASX Release 5th Dec 2016) and 15km northwest of the Bounty Gold mine. Zenith commenced exploration of the Split Rocks project in 2017 with active and ongoing programs focusing on the lithium and gold potential.  As detailed in Zenith’s ASX releases (14th September 2017 and 4th December 2017) first pass surface samples taken at Split Rocks, to date covering less than 10% of the Company’s tenements, have defined three large, coherent zones of anomalous lithium, caesium and rubidium surrounding granite bodies that may be potential source rocks for lithium bearing pegmatites.  The tenor of these large scale lithium anomalies is comparable with competitor surface results that upon drilling have returned significant bedrock lithium mineralisation in several instances.  Field follow-up indicated very little to no outcrop in the areas of the lithium soil anomalies and that drill testing will be required.  As the lithium soil anomalies remain open ended in the north and central target areas, additional extension and infill sampling will be completed prior to drill testing.

The Split Rocks project also has strong potential for gold mineralisation. There are two main gold trends in the Forrestania Greenstone Belt - an eastern gold trend that includes the Bounty gold mine and associated smaller scale gold deposits extending north to Marvel Loch and Southern Cross, and a second gold trend on the western side of the greenstone belt which includes mined deposits at Van Uden and Teddy Bear as well as those under assessment by ASX:CLZ at Lady Ada and Lady Magdalene (240k oz gold).  Zenith’s Mawson and Casey gold surface anomalies lie along this western trend within an area of dense scrub vegetation that has historically limited access and resulted in historically lesser exploration activity. Systematic surface geochemical sampling by Zenith confirmed and extended two high-order gold auger anomalies Mawson and Casey (ASX Release 17th September 2017). 

On the eastern gold trend historic shallow RC drilling completed in 2005 north east of the British Hill gold deposit, which is located between Zenith’s new exploration licences, intersected significant gold mineralisation with results including: 34m @ 0.48g/t gold (Au), including 7m @ 1.57 g/t Au from 37m depth, open to the south west (as previously reported in ZNC - ASX Release 16th August 2016).  Nine of the thirteen drill holes returned 1m intercepts greater than 0.5 g/t Au ranging up to 1m @ 8.6 g/t Au.  Mineralisation is hosted within saprolite clays and weathered ultramafic rocks with associated quartz veining and minor pyrite.  This gold mineralised zone remains open to the south and was not followed up by previous explorers.

Zenith has also identified additional potential for cobalt and nickel at Split Rocks, the Company will commence a program in 2018 to define the full extents and grade of the cobalt-nickel mineralisation at the Dulcie Prospect. Previous drilling in 1998 to test for gold mineralisation at the Dulcie Prospect by Forrestania Gold NL and reported to the Western Australian Mines Department in open file report A56331 returned strong cobalt and nickel in a near surface, flat lying, saprolite clay blanket-type body. In total 13 drill holes, of which only 8 have been analysed for cobalt and nickel were completed over 4 drill lines, covering only 400m of strike.  The cobalt – nickel mineralisation remains open in all directions with a further 9km of strike potential of interpreted host ultramafic unit within Zenith’s tenure that is yet to be tested.  Cobalt rich drill results include: FDUP002 18 - 40 metres, 22 metres @ 0.06% cobalt and 0.70% nickel including: 8m @ 0.12% cobalt and 0.96% nickel, and FDUP003 25 – 46 metres: 21 metres @ 0.06% cobalt and 0.49% nickel, including: 5 metres @ 0.13% cobalt and 1.78% nickel.
