Numerous intersections of spodumene-bearing pegmatite encountered in drilling at the Muvero prospect in Africa have provided “great encouragement” for owner Tyranna Resources (ASX: TYX).

Drilling commenced in early November and almost immediately intersected pegmatites containing lithium mineralisation.

The company has since completed 10 holes for a total of 1,650 metres which aim to trace the continuation of well-developed spodumene discovered in 2022.

The holes have produced drill cuttings with visible spodumene occurring mostly as phenocrystic megacrysts in a coarse-grained matrix comprised of cleavelandite and quartz, with minor amounts of lepidolite, elbaite, muscovite, and microcline.

As drilling continues, it is expected that Tyranna’s understanding of Muvero will increase and interpretations of the mineralisation will evolve.

The results will be used to prepare a maiden mineral resource estimate for the Muvero prospect.

Expanded campaign

Technical director Peter Spitalny said the company planned to expand its drilling campaign from 6,000m to 8,000m at Muvero and other prospects in the new year.

“The continuing intersection of spodumene-bearing pegmatites reinforces the potential of the Muvero prospect to contain a substantial amount of spodumene,” he said.

“We are optimistic that as drilling continues and extends into 2024 this will prove to be the case.”

Drilling schedule

Tyranna’s current drilling program will pause over the Christmas period and restart in January.

As drilling progresses, samples will be dispatched to ALS Namibia for processing into pulps after which they will be exported to Australia for further analysis.

Receipt of assays from the first batch of samples is expected in January for validation and reporting.

Investment funding

In August, Tyranna received $14.5 million in investment funding from China’s Sinomine Resource Group, which enabled the design of an extended drilling program to incorporate the “link zone” to Muvero East.

Recent mapping revealed the zone to contain several pegmatites and Tyranna believes that additional mineralisation could supplement any resources identified at Muvero.

Drilling to test Muvero East will commence in the new year after the company has secured rig access.
