Announcement PDF 23 May 2023 ASX ANNOUNCEMENT PHASE 2 DRILLING TO COMMENCE ON SCHEDULE AT NEVADA LITHIUM PROJECT Highlights ▪ Planning and permitting for Phase 2 RC drill programme at the 80% owned Nevada Lithium Project (NLP) is now complete with commencement of drilling imminent. ▪ Drilling on schedule to commence in the first week of June 2023 targeting extensions of the thick Lithium (Li) claystone intercepted at Western Flats earlier this year, which included the discovery holes which intercepted: o 109.7m @ 766ppm Li from 135.6m depth to end of hole (WF23-011) (mineralisation remains open) ▪ o Including 29m @ 1,010ppm Li from a depth of 210.3m 44.2m @ 570ppm Li from 169.2m (WF23-006) ▪ Further 36 claims have been staked at the highly prospective Western Flats and Lone Mountain, increasing the NLP footprint. ▪ Holes planned at: Western Flats, Lone Mountain, and the untested Heller prospect Future Battery Minerals Limited (ASX: FBM) (FBM or the Company) is pleased to announce that the Phase 2 reverse circulation (RC) drilling programme at the Nevada Lithium Project (NLP), NV. USA (Future Battery Minerals 80%) is on schedule to commence in the first week of June 2023. The Phase 2 programme planning and permitting has been completed and approved with earthmoving and drilling due to commence within the next fortnight. The 3,000m Phase 2 drilling programme is aimed at extending the known Lithium (Li) claystone horizon intercepted in drill hole WF23-011 at the Western Flats Prospect, which terminated within mineralisation1. The significant intercept of 109.7m @ 766ppm Li from a 135m down-hole depth, importantly hosted a high-grade portion of 29m @ 1,010ppm Li. Based on regional mapping observations, the FBM geological team believe there is a high potential for the shallow mineralisation to extend south and west onto the Lone Mountain Prospect. This could potentially add large scale mineralisation from this style of deposit at both prospects. Drilling will also test the regional Heller Prospect, where 2-4 RC drill holes will test the stratigraphy for Li claystone potential. In addition, the Company has expanded its project area via the addition of 36 new claims located contiguous to Western Flats and Lone Mountain (Figure 1). Located on the western margin of the two prospect areas, the additional ground increases FBM’s footprint in this highly prospective area of the NLP, increasing the opportunity to find additional mineralisation. The Phase 2 drilling programme will also test this newly staked ground. FBM Technical Director Robin Cox commented: “Following the outstanding results of the NLP Phase 1 RC programme in April 2023, FBM’s in-country team has worked expediently to reach this drill ready stage. With permitting now approved, we look forward to commencing drilling within the next two weeks. In addition to planning and preparation works, the team has 1 Refer to 13 April 2023 ASX Announcement – High Grade Lithium Claystone Discovered in Nevada Future Battery Minerals Ltd info@futurebatteryminerals.com.au Suite 10, 38 Colin St, West Perth WA 6005 +61 8 6383 7817 ABN 91 148 966 545 futurebatteryminerals.com.au ASX:FBM Follow Us 1 staked highly prospective ground contiguous to Western Flats and Lone Mountain. The plus 100m thick intercept at WF23-011 remains open to the south and west at depth and given the hole ended in mineralisation, provides the potential for the NLP prospects to host large scale, high tonnage mineralisation.” The Phase 2 RC drilling programme will be managed by the Company’s highly competent in-country team, with assistance from the West Australian based technical team. The Company has again engaged drilling contractor Alford Drilling LLC (Alford) who completed the Phase 1 drilling programme in a safe and efficient manner. Alford will be providing a larger RC rig for this programme as planned depths have increased given the intersection of WF23-011 reached the previous drill rigs depth limitations. Following the receiving of the Phase 1 assay results, this significant next step in exploration at NLP is highly anticipated and the FBM team look forward to the commencement of drilling.
