Zenith Minerals Limited announced that diamond core drilling in a 200m step-out hole confirms thick high-grade lithium mineralisation at the Split Rocks project in Western Australia. In addition, deeper core drilling shows that pegmatite extends or repeats, by up to a further 100m, below many RC holes. The Split Rocks project is part of the Zenith Lithium Joint Venture with EV Metals Group.

Core Drilling Delivers Wide High-Grade Lithium and Confirms Pegmatite Extends to Depth The first diamond core assays have now been received from an ongoing drilling campaign at the Rio Pegmatite part of the 600km2 Split Rocks Project located in Western Australia. New lithium drill results from drill hole ZVCD039 (diamond core tail to ZVRC039) include: 26m @ 1.2% Li2O incl. 13m @ 1.9% Li2O (upper zone) and 23m @ 0.8% Li2O incl.

8m @ 1.3% Li2O (lower zone). These lithium results over two intervals total 49m in thickness. Mineralisation is a 200m step out to the south and 2The project area lies immediately north of the Mt Holland Lithium Project that is being developed by Covalent Lithium (SQM and Wesfarmers).

Drilling as part of an ongoing exploration campaign to scope the size of the host pegmatite and contained lithium mineralisation at Rio has returned significant lithium mineralisation. Lithium pegmatite mineralisation identified to date is a mixture of eucryptite with lesser spodumene, petalite and lepidolite confirmed by multiple methods including optical microscopy, SEM, Raman spectroscopy and XRD analyses. The amenability of eucryptite mineralisation to conventional treatment processes has been shown by positive sighter flotation testwork and bench scale calcination-leach tests, hence confirming the potential of eucryptite as a viable lithium target.

These lithium results over two intervals total 49m in thickness. Mineralisation is a 200m step out to the south and 200m east of previously reported mineralised holes ZVRC037 (25m @ 0.7% Li2O, incl. 5m @ 1.1% Li2O & 3m @ 1.1% Li2O & 2m @ 1.2% Li2O) and ZVRC040 (ZVRC040 - 12m @ 0.6% Li2O, incl.

4m @ 1.2% Li2O). Diamond drilling also confirms that pegmatite continues or repeats at depth below many RC drill holes. For example, new diamond core hole ZVCD079 shows that pegmatite extends some 100m below the RC drill hole ZVRC043.

Pegmatite has now been outlined over >2,400m length and >2,400m width (remaining open), with a lithium mineralised zone (>0.1% Li2O) identified over >2,100m by 1,000m. Within this zone an open-ended higher-grade (>0.3% Li2O) lithium zone extends for greater than 650m in length, remaining open to the north, south, east and at depth. Drilling now refocused from the wider scout program to defining the higher-grade lithium zone with mineralisation remaining open to the north, south, east and at depth.
