Metallurgical Scoping Study, San Domingo Pegmatite Project-Moving Further Along the Potential Production Pathway, Completion of TSX-V Delisting

Bradda Head Lithium Ltd (AIM:BHL), the North America-focused lithium development group, is pleased announce the commencement of a further metallurgical particle sorting study on the composite samples collected in 2023 from San Domingo drill core. The purpose of this new test-work plan in addition the 20 November 2023 reported metallurgical work, is to move Bradda Head closer to a potential production decision later in 2025.

The study will be supervised and guided by ABH Engineering Inc.("ABH"), an international leader in scoping, design, and installation of mineral processing facilities for the mining industry. ABH, located in Vancouver, BC, Canada, will oversee the scoping study which will investigate the potential to increase mill feed grade, reduce product impurities, and reject baren rock before it enters any milling process. The goal of testing is to lower cut-off grades and increase potential profit.

Essential elements the Company is looking to achieve from the scoping study are:

  • Increased mill feed grade, resulting in higher metal production, lower OPEX, higher mill recoveries, and potentially, increased NPV;
  • Early barren rock rejection to reduce fine tailings, reduce transportation costs, examine potential for direct shipping or high-grade local ROM (run-of-mine), reduced toll milling charges, reduce mill and tailings for lower CAPEX, and lower environmental impacts such as lower water consumption, reagents, footprint;
  • Examine waste sorting and lower cut-off grades that result in dramatic increase in reserves and resources, potential to extend mine-life; and
  • It is also important to note that market quality Li2O concentrate (Li2O grades of 6.0% from ¼" crush and 5.5% from 3/8" crush) was produced previously from a 1.03% Li2O composite drill hole composite samples using dense media separation (DMS), a simple low-cost gravity approach (PR Nov 20, 2023).

The study will utilize AI-powered XRT or laser sorting machines that, in part, will examine potential mechanisms to sort lithium mineralized rock (spodumene) from gangue rock such as quartz, feldspar, and muscovite. The systems incorporate dual energy x-ray transmission or laser sensors to identify valuable minerals, generating results that could provide data to determine high-level economic models, obtain grade recovery curves, profit recovery curves, and lead to quantified economic ore sorting changes to CAPEX and OPEX.

Ian Stalker, Executive Chairman, commented:

"We're excited to embark with this new AI-powered analysis which we believe will add to the positive gravity concentrate metallurgical results from 2023. We believe we're on the path towards developing mineable resources at San Domingo, and these additional mineral and metallurgical results may well be pivotal towards unlocking the near-term value on this US based pegmatite project."

As a reminder of the 20 November 2023 PR, metallurgical results reported SGS Canada commissioned HLS (heavy liquid separation) testing on a 1.03% Li2O composite from Jumbo target drill holes from San Domingo. The test produced encouraging results:

  • The 1.03% Li2O sample produce an 'in spec' lithium oxide concentrate product with a 6.0% Li2O grade and an interpolated recovery of contained lithium to the concentrate of 50.3%, at a ¼" size crush size. Tailings rejection was considered efficient in this scenario with the rejection of 60.6% mass and a loss of only 2.1% lithium.
  • Alternately, at a crush size of 3/8" (9.5 mm), a concentrate was produced with a grade of 5.5 % Li2O at a 55.5% recovery of contained lithium oxide. This is still considered in spec in the current market.
  • Using the medium-grade sample, the flotation feed, a combination of middling product from the HLS testing at a crush size of ¼" and under sized fraction (minus 0.85 mm), recorded an upgraded value of 1.57% Li2O with Li distribution of 47.0% and a mass distribution of 30.5%.

TSX-V Delisting

The Company also confirms that its ordinary shares have been delisted from the TSX-V. The delisting will not affect Bradda Head's listing on AIM and its ordinary shares will continue to be listed on AIM under the symbol "BHL".
