Sovereign Metals Limited: Drilling Triples Mineralised Area at Kasiya
(firmenpresse) - Sovereign Metals Limited (the Company or Sovereign) is pleased to announce Phase 7 drill results from Kasiya, the Companys flagship, large, high-grade rutile deposit in Malawi. This substantial batch of drill-holes has tripled the rutile-mineralised footprint to ~66km2.
HIGHLIGHTS
- Phase 7 drilling has substantially extended the strike length of the rutile-mineralised envelope to over 16km with widths of up to 6km (previously ~7.5km by up to 3km)
- Mineralised envelope has tripled in footprint size to ~66km2 (previously ~22km2)
- Numerous new areas of high-grade rutile defined (see highlight results on page 2)

Sovereigns Managing Director Dr Julian Stephens commented:
This is an incredible outcome with a three-fold increase of the rutile-mineralised footprint to over 66km2. These new drill results show a step-change increase in the potential size of Kasiya and highlight that it could well develop into one of the largest rutile deposits in the world. In conjunction with the recent exceptional metallurgical outcomes, these results confirm our view that Kasiya is quickly becoming a globally significant rutile deposit.

KASIYA DRILLING - PHASE 7
The Phase 7 results include extensional and infill drilling comprising a further 82 hand-auger holes (50 extensional and 32 infill) for a total of 819m. With the inclusion of Phase 7 the total number of holes reported from Kasiya to date is now 233 with 2,298m drilled.
This drilling has substantially extended the strike length of the rutile-mineralised envelope to over 16km and expanded the width to up to 6km (Figures 1, 2 and 3) from the previous 7.5km by up to 3km.
In terms of area, the mineralised envelope has approximately tripled in footprint size to ~66km2 from the previous ~22km2. The mineralised envelope continues to remain open along strike to the north and south, and laterally at its widest zone to the east.
A number of the extensional holes were drilled to the east, north and south-east of the core mineralised zone at a nominal 400m x 400m drill spacing and fall within the targeted area for the upcoming Mineral Resource Estimate (MRE) (Figure 2). These extensional holes have provided a significant expansion to the widest, central core zone of high-grade rutile mineralisation. A significant number of high-grade rutile drill intercepts from surface were encountered in these holes.

Figure 2. Close-up of the central zone of Kasiya showing the area designated for consideration in the maiden MRE.
The infill drilling results continue to show high rutile grades from surface, as expected, with the infill drill holes limited to the central portion of the main resource target area.
The Phase 7 drill results continue to show high-grade rutile from surface to as deep as 16m. Significant rutile enrichment is generally present in the 0-8m from surface range. In most cases, drill depth was restricted by the hand-auger drilling equipment capacity and it is assumed that free-dig rutile mineralisation should continue vertically to the base of saprolite estimated at approximately 25m depth from surface.
These results continue to validate the Companys geological exploration model and provide a step-change in the potential size of Kasiya. It is now clear that Sovereigns geological team has the ability to predict, with some accuracy, new areas of rutile mineralisation prior to any on-ground soil sampling or drilling. If the Companys geological exploration model continues to hold true regionally, the rutile potential across Sovereigns exploration licences in Malawi is immense.

CONCLUSIONS & FORWARD PLAN
In a step-change for Kasiya, this substantial batch of the Phase 7 drill results has increased the mineralised footprint area three-fold. The results continue to build on the previous phases of drilling with high-grade rutile consistently intercepted from surface across the now 66km2 mineralisation footprint.
The central zone of ~30km2, where the nominal drill spacing is 400m x 400m or closer, will be under consideration for the maiden MRE. The Companys objective is to delineate a large rutile resource that could support a long-life, large-scale rutile operation.
Additionally, Sovereign has recently achieved exceptional outcomes from its bulk scale metallurgy program. Premium chemical and sizing parameters were produced with over 98% recovery, via simple, conventional off the shelf processing methods. This continues to consolidate our view that we have discovered a potentially globally significant rutile deposit at Kasiya in Malawi that forms part of a new rutile province.
The ongoing work programs for Kasiya and the other prospects within the Companys large ground package include;
- Reporting of one further batch of mainly infill drill holes over the coming weeks ahead of the maiden Mineral Resource Estimate for Kasiya targeted for Q4 2020;
- Step-out and extensional drilling at Kasiya and the broader surrounding area to identify extensions and discover new regional mineralised zones;
- Push-tube drilling at Kasiya to twin hand-auger holes and to obtain cored samples for specific gravity (SG) determination and initial geotechnical and mining studies;
- Mining and tailings studies continue and will feed into a future Scoping Study targeted for H1 2021;
- Feedback from rutile product sample assessment by major industry end-users to be incorporated into marketing studies in support of the upcoming Scoping Study; and
- Investigation of the potential for a coarse-flake graphite by-product from Kasiya.

A NEW RUTILE PROVINCE
The Central Malawi Rutile Project (Project) features two confirmed, discrete rutile mineralisation styles hosted saprolite (soft, friable weathered material) and sand. Both styles are amenable to conventional processing.
In addition to the flagship Kasiya, the Company has identified numerous other saprolite-hosted rutile prospects and targets. The Bua Channel is the Companys high-grade, rutile dominant, sand-hosted placer prospect along a 50km length of a fluvial channel system. Drilling in the southern part of the Bua Channel over ~8km confirmed excellent rutile grades with accessory ilmenite.

This potentially globally significant rutile province is located in Malawi, a stable, transparent jurisdiction. Malawi is increasingly attracting international investment with substantial potential for mining to contribute to the countrys economic growth and development. Central Malawi boasts excellent existing infrastructure including grid power and an excellent sealed road network. The Project is strategically located in close-proximity to the capital city of Lilongwe, providing access to a skilled workforce and mining and industrial services. The location provides access to the operating Nacala Rail Corridor linking to the Indian Ocean port of Nacala in Mozambique, providing a low-cost transport solution and access to major international markets.
