Tin – from Zaaiplaats to Afritin


30 October 2017

Following the announcement that Afritin would be demerging from BMN and listing on AIM it is worth going over the history of the Tin platform.

26.04.12 RNS – Announces commencement of drilling at Groenfontein and Zaaiplaats targets (2 of 5 targets within the Mokopane tin licence area) to extend the former and define the latter resources, and commencement of metallurgical work.

04.12.12 RNS – Company looking to expand the 5,000 ton JORC resource at Groenfontein. Also at Zaaiplaats the findings of this work supported the model that an extensive zone of disseminated tin mineralisation at acceptable grades is present in and around the old Zaaiplaats tin mining area. Initial Zaaiplaats drilling results included.

13.12.12 RNS – Results from mineralogical tests conducted at Zaaiplaats displaying similar characteristics to historical mining records, as well as significant potential for resource expansion. Good liberation of cassiterite through all size fractions.

25.06.13 RNS – Mineralisation intersected in almost every borehole. Confirmation of two continuous, near surface, shallow dipping zones of mineralisation. Results included. Confirms the prospectivity of the Zaaiplaats target.

19.09.13 RNS – 12,452 tons JORC at Zaaiplaats, mostly inferred. Cut off 0.7%. Deposit open along strike to NE and SW so possible to extend. Together with Groenfontein gives JORC for Mokopane 18,447 tons contained tin.

26.09.13 RNS – To acquire 50% of Marble Hall project for upfront payment of £126,000. Commitment to spend £270,900 to bring project to pre-feasibility. Further payment of £315,000 subject to completion of pre-feasibility, and a decision to progress to bankable feasibility study and/or development. 110 km from Mokopane. Historic data by Goldfields from 1980’s. Target Maiden JORC 2014.

29.10.13 RNS – Initial drilling at the Marble Hall Tin Project confirms the presence of a mineralised breccia including an intersection of 1.39% tin (Sn) over 1.75 m.and 0.88% Sn over 1.00 m. Results increased confidence in historical Goldfields data.

25.03.14 RNS – Agreement to acquire the Zaaiplaats tin tailings dump. The Company will acquire an equity interest of up to 87% in Zaaiplaats for a total consideration of up to R10 million (equivalent to £559,470 as of March 25 2014) as described below. This agreement is conditional on the outcome of technical due diligence and evaluation of the Zaaiplaats Dumps, to be undertaken by Bushveld over a two month period, which commenced on 20 March 2014.

22.05.14 RNS – Bushveld has agreed with the owners of the Zaaiplaats Dump, Brent Trust and Sephaku Tin (Pty) Ltd, to extend the technical due diligence and evaluation period in respect of the potential acquisition by a further six weeks to 30 June 2014.

16.09.14 RNS – Results of scoping study and decision not to pursue Zaaiplaats tin tailings dump.

Scoping study gives low CAPEX at $16.7 million. Pre tax NPV $18 million, post tax NPV $10 million (at 10%). Pre tax IRR  49.8% post tax real IRR 34.6% with low project risk profile. Low operating costs (C1 cash + Royalties costs of $14,276 / ton of tin metal). Average EBITDA of 31.5% over 12 year mine life. Payback 2 years from start of mining.

The Company also announces the outcome of its technical due diligence conducted for the potential acquisition of the Zaaiplaats Tin Tailings Dump (the “Zaaiplaats Dump”). Bushveld has elected not to pursue this acquisition on account of the unsatisfactory results of the due diligence exercise, with the realisable size and grade of the tin resource contained in the Zaaiplaats Dump as well as the realisable recoveries inadequate to meet the Company’s acquisition criteria. Accordingly, the Zaaiplaats Dump is excluded from the Scoping Study reported herein.

17.03.15 RNS – Lemur acquires Zaaiplaats tin tailings dump for Aus$270,000 (£160,000 at exchange rate 24.10.2017). Possible to sell sand / aggregate from non tin bearing materials.

20.06.16 RNS – The Groenfontein Deposit test work was intended to assess tin recovery on a plant-scale, gain insight into potential concentrate grades, and to fine-tune plant flow-sheet design parameters. The test work has delivered the following positive results: Expected recovery using gravity concentration of over 70%, for grind sizes of -1 mm;  Achieved commercial concentrate grade of 74.59% SnO2 (cassiterite – equivalent to 58.75% Sn);  Plant design and flowsheet underway;  Final costing underway to determine capital and operating expenditure requirements for mining and processing plant establishment, together with ancillary infrastructure;  Results to be incorporated into an updated business model focusing on the smaller-scale, near surface high-grade tin targets near-term production.

28.11.16 RNS – Under the terms of the MoU, VBKom commits to conduct due diligence on the Mokopane Tin Project, following which, if a successful outcome, VBKom intends to enter binding agreements to provide capital investment and technical support for the development of the Groenfontein and Zaaiplaats deposits to mine commissioning in return for equity participation in the project, not exceeding 50%. The MoU provides for VBKom to conduct due diligence on the Mokopane Tin Project for a period to 31 January 2017.
