Pitfield TiO2 Mineralogy & Processing18 Jun 2024 15:34
As Pitfield mineralogy and processing is now at the forefront of investor attention it seems timely to highlight a 10 page “Technical Appendix” to the March 5th RNS which appears to have been overlooked by most since it is not mentioned or quoted by anyone here. The link to the Appendix is below:
http://www.rns-pdf.londonstockexchange.com/rns/6096F_1-2024-3-5.pdf
When evaluating the content it is important to bear in mind that the various studies described apply to samples from RC and/or DD holes from Mt Scratch and the Thomas target, mostly at sub-40m depths and so not representative of the rutile/anatase enriched weathered zone. The TIMA image [Fig 2] and the CSIRO Microprobe BSE image [Fig 3] appear to be from sub-40m unweathered titanium and Ti-bearing Fe oxide enriched bedrock. Note: the BSE [Backscattered Electron] image is obtained using QEMSCAN technology, the supposed absence of which has been a prime example of misinformation by an accusatory and spurious contributor to this chat-site. QUEMSCAN is a propriety technology of the mineral resources division of CSIRO, Australia's national science agency, with which EEE's association is of primary importance.
Although relating to the deeper titanite resource, and therefore of less immediate interest compared with the overlying rutile/anatase resource, the above TIMA and BSE images do provide promising indications of a mineralogy conducive to physical disaggregation and subsequent processing. The titanite and Ti-bearing Fe oxides are distinct and predominant, with the Fe end of the Titano-Hematite to Hemo-Ilmenite series in low % terms. This is well supported by the Wet Gravity Separation Diagnostic Testwork [pages 4-6] based on samples from 88m depth at Thomas and 170-180m depths at Mt Scratch, which in summary “provides confidence that minerals can be recovered by gravity separation”. Analysis of the two samples indicated a TiO2 content of around 67% from the titanite minerals [ref pages 6/7]. The remainder [pages 7-10] of the Appendix is a more comprehensive account of the “Metallurgical Processing Options” and the “Potential TiO2 Products” outlined in the RNS. Presumably much of this will be updated from subsequent and in-progress studies more appropriate to the priority rutile/anatase resource.
