Zenith Minerals (ASX:ZNC) has received preliminary four-metre composite assay results from recent RC drilling at the Dulcie lithium prospect, part of the company’s Split Rocks project in WA. Drilling tested a 950m-long zone of pegmatites, from which shallow aircore drill holes in the maiden program returned strongly anomalous lithium results, and has confirmed the presence of thick pegmatite bodies.
- Assay results from recent RC drilling at the Dulcie prospect confirm lithium fertile chemistry of pegmatites intersected at Split Rocks;
- Best chemical signature from base of thickest pegmatite (77m downhole width) in northernmost drill hole – follow-up RC drill testing required; and
- Planning underway to drill test seven other large scale lithium soil anomalies.
Zenith Minerals Limited (“Zenith” or “the Company”) is pleased to advise that preliminary 4 metre composite assay results have now been received from recent RC drilling at the Dulcie lithium prospect, part of the Split Rock project located 40 km north of Kidman Resources’ (ASX:KDR) Mt Holland (Earl Grey) lithium pegmatite deposit containing 189Mt @ 1.5% Li2O (KDR ASX Release 19th Mar 2018). Zenith’s 100% owned Split Rocks Project covers a large portion (total area >500sqkm) of the Forrestania Greenstone Belt of Western Australia (Figure 3).
Zenith’s recent RC drilling at the Dulcie target tested a 950 metre long zone of pegmatites, from which shallow aircore drill holes in Zenith’s maiden program returned strongly anomalous lithium results up to 2m @ 0.12%Li2O, and has confirmed the presence of thick pegmatite bodies (up to 77m downhole widths) – ASX Release 31st July 2018.
The assay results now received from initial 4m composite sampling of the RC drilling confirm that the basal portion of the thick pegmatite intersected in drill holes ZDRC003 and ZDRC006 from the northernmost drill holes has a chemical signature similar to those of major Western Australian lithium spodumene mines such as Greenbushes, Pilgangoora, Bald Hills, and Mt Cattlin and also similar to that of the nearby Mt Holland (Earl Grey) lithium deposit, (Figures 1 2, & 4). The lithium content of the Dulcie pegmatites in the composite samples is strongly anomalous (80m @ 353ppm Li2O in drill hole ZDRC006, with a peak value of 4m @ 917ppm) similar to the levels reported from prior aircore drilling, and also increases to the north and with depth, providing an additional exploration vector (Table1). The untested area north of the current drilling therefore presents a strong drill target for further follow-up testing. One metre resampling will be completed as soon as possible before permitting of follow up drilling.
