Tyranna Resources (ASX: TYX) has discovered lithium pegmatite 350m southeast of the Muvero Prospect confirms large mineralized systems present at Muvero in Angola.
Along with completion of other tasks pertaining to planned drilling in the months ahead and providing a guided tour of the project to Sinomine Resource, Tyranna initiated investigation of unexplored parts of the Namibe Lithium Project.
Investigation of 34 pegmatites that have never been examined by any previous explorers was completed through on-foot ground traverses, resulting in the discovery of four new lithium prospects.
“The discovery of lithium mineralization in pegmatites located in distal unexplored parts of the project was predicted and supports Tyranna’s interpretation of the nature of Giraul Pegmatite Field,” Technical Director, Peter Spitalny, said.
“It also confirms that lithium pegmatites are widespread and not restricted to those areas that have seen historical activity, implying that many more are likely to be discovered as exploration continues.
“We are particularly excited by the discovery of the lithium pegmatite 350m southeast of the Muvero Prospect, supporting the interpretation that the scale of lithium mineralization at Muvero is substantial and the prospect has the potential to be economically significant!.”
Traditional “boots on the ground” fieldwork was completed that included some more-distal parts of the project. A total of 34 pegmatites were investigated and lithium mineralization was recognized in four of these pegmatites, which were sampled. In addition, samples were also collected from two other pegmatites (21l and 22b) that had been inspected previously.
A total of 18 samples (NR053 to NR070 inclusive) were collected and assay results are anticipated to be received in June and will be reported to the market as soon as possible.
Although use of a helicopter was arranged to support the reconnaissance of the remote pegmatites, this was deferred to focus on the next drilling campaign and due to the time commitment required for the Sinomine site visit.
The discoveries made in the recent fieldwork, along with an evolving improved understanding of the Giraul Pegmatite Field in general, emphasize the high lithium prospectivity of the remote parts of the project and confirms that the helicopter-assisted reconnaissance is essential. This important fieldwork will be rescheduled for completion prior to the next drilling campaign.
Next Steps
Assay results from sample NR053 – NR070 are expected to be received in June and will be reported as soon as possible.
Additional access tracks, improvements to existing tracks and preparation of drill-pads have commenced and is progressing well. Along with this, activities to optimize the efficiency of the drilling program, including establishment of a camp within the project area and securing local skilled personnel, have commenced.
Preparation for drilling is well advanced, with contractors and personnel secured. Commencement of drilling is currently expected to occur in August.
Prior to commencement of drilling, in June it is intended to complete helicopter-assisted reconnaissance of the projects’ remote pegmatites. This has been deferred to focus on the next drilling campaign and due to the time commitment required for the Sinomine site visit. There are three main areas that will be focussed upon, labelled A, B and C in Figure Pegmatites were investigated during the 1960’s to early 1970’s by the Portuguese, on behalf of the Angolan government as part of regional mapping and recent investigations by Angolan Minerals Pty Ltd and Tyranna.
The total number of pegmatites inspected to-date is 182, about 18% of the pegmatites present that have an outcrop of about 100m length or greater.
Within Area A (the largest area) there are at least 200 pegmatites that have never been investigated in any way, including some very large pegmatites. The potential to discover significant lithium mineralization in this area is very high.
