Arcadia Minerals Limited (ASX:AM7, FRA:8OH), the diversified exploration company targeting a suite of projects aimed at Tantalum, Lithium, Nickel, Copper and Gold in Namibia, is pleased to announce that Snowden Optiro has provided the Company with an Independent Geological Report titled “Report for Orange River Pegmatite Geology and Resource Estimation of the D, E and F Pegmatites, Project Number JB018308, May 2022” 1 which consist of a revision of a Mineral Resource Estimate, announced by the Company on 23 September 20212 , for the Company’s 80% owned Swanson Tantalum exploration project situated in Tantalite Valley, Namibia.

  • Revision of September 2021 Mineral Resource delivers a new estimate including a total indicated and inferred resource of 2.59Mt (an increase of 115%) at an average grade of 486 ppm Ta2O5 (an increase of 17.9%), 73 ppm Nb2O5 and 0.15 % Li2O.
  • Total in situ metal content of 1,257 tonnes (represents an increase of 154%)
  • Mineral Resource Categorisation:
    • Indicated Resource: 1,439Mt at an average grade of 498 ppm Ta2O5, 72 ppm Nb2O5 and 0.14 % Li2O,
    • Inferred Resource: 1,145Mt at an average grade of 472 ppm Ta2O5, 75 ppm Nb2O5 and 0.17 % Li2O
  • To date only 15 of the more than 200 known pegmatites present over Arcadia’s three licenses have been explored.
  • Mineral Resource Estimate conducted over 10 (of 15) outcropping opencastable shallow pegmatites located at Swanson, namely the D0, D1, D2, E2, E3, E4, E6, E7, E8 and F1.
  • Public domain information from 11 Tantalum operations from around the world were used to benchmark the Swanson project against other Tantalum projects. The weighted average grade of these 11 deposits is 233 ppm Ta2O5, indicating that the Swanson Project grades are significantly above its global peer group and of the highest grades in the world.
  • The Mineral Resource Estimate is to form the basis of a feasibility study currently underway (expected to be completed in September 2022).
  • Mineral Resource is based on an exploration program that includes:
    • 283 channel / chip samples and
    • 52 diamond boreholes on a 50m grid spacing

Philip le Roux, the CEO of Arcadia stated:

“When the company commenced the phase 2 drilling program at Swanson the primary objective was to increase the previous JORC resource of 1,214Mt @ 412 ppm Ta2O5 we set out to increase the resource to more than 2.5 million tonnes. It is very pleasing to announce that we’ve achieved this goal and more, by attaining an 18% higher grade than what was reported under the maiden Mineral Resource published in September 2021. The results bode well for the Company’s upcoming feasibility study, which is already underway with an outcome expected by September 2022.”

Jurie Wessels, the Executive Chairman of Arcadia stated:

“With this impressive result our priority for the Swanson project has progressed towards the feasibility study, with the aim to demonstrate that the production of a 25% Ta2O5 concentrate is feasible and to prove that Swanson will become the cash generator we envisioned it to be for Arcadia. Additionally, we’ll aim to explore the abundant pegmatite swarms scattered throughout our licenses in Tantalite Valley to possibly replicate the resources we discovered at Swanson and thereby increase more value for our shareholders.”

Revised Mineral Resource Estimate

Through its 80% owned subsidiary Orange River Pegmatite (Pty) Ltd (“ORP”) Arcadia ownsthe exploration rights to three EPL’s (5047, 6940 and 7295). The total amount of pegmatites mapped by the South African Council of Geoscience over the three ORP EPL’s amount to more than 200 pegmatites (see Figure 1). All indications are that the same mineralisation model present in the 15 pegmatites explored to date at Swanson could be applicable to these pegmatites.

Fifteen individual pegmatite bodies > 1 m thickness within the Swanson Pegmatite Swarm were identified as high priority and were then targeted for mapping, sampling and drilling. This area was delineated, and a high-resolution drone survey was undertaken to assist with the planning of the exploration program. The pegmatite units were clustered and named “A” to “F” in a west to east direction as shown in Figure 2.
