Initial drill program intersects wide pegmatite mineralisation
- Initial due diligence drilling completed
- All holes intersected pegmatite dykes and confirms lithium mineralisation continues at depth below surface outcrops and old workings
- Lithium minerals including Spodumene and Lepidolite identified in all pegmatite drill intersections
- Down-hole pegmatite drill intersections of up to 9m, 14m and 36m*
- Pegmatite dykes intersected down to approximately 60m vertically below surface outcrops
- Assay results from the program are expected to be returned in August
*Note: 36m intersection was from a hole drilled sub-parallel, or down-dip, of a pegmatite dyke
Six Sigma Metals Limited (“SI6” or the “the Company”) is pleased to announce the completion of a Reverse Circulation (“RC”) drilling program at Bonnyvale, a high priority pegmatite prospect at the Shamva Lithium Project (“the Project”). The program was designed to test if lithium mineralisation continues at depth as part of SI6’s due diligence assessment of the Project (see ASX Announcement 12 June 2018).
The 5-hole drilling program successfully intersected pegmatite dykes containing visible lithium minerals including spodumene and lepidolite in every hole and has provided the company with important information about the geometry and thickness of pegmatite dykes at Bonnyvale. Once assay results are received (expected in August), the Company will have further valuable information regarding the continuity and tenor of lithium mineralisation within the dykes below surface outcrops.
Key findings of the program include:
- All holes hit pegmatite of varying thickness. The thickest single dyke has an interpreted true thickness of between 10 – 12m (from holes 4 and 5, see Figure 4 below);
- All pegmatite intersections have contained identifiable spodumene and lepidolite mineralisation within the RC chips;
- Pegmatites occur as either thick dykes (holes 4 & 5) or narrow, sheeted dykes (Holes 1 – 3); and
- Pegmatites extend to at least 60m depth vertically below the surface, as evidenced in holes 1, 2 and 5.
DRILLING COMMENCES AT HIGH PRIORITY LITHIUM TARGET
- Drilling program commenced at Shamva for a minimum of 3 holes and 300 metres at the Bonnyvale target.
- Flexibility to expand drilling program pending initial results.
- The aim of the drilling program is to identify thickness of lithium mineralisation and if it continues at depth. Recent surface rock samples over the Bonnyvale returned lithium grades of over 2% Li2O.
- Surface samples from nearby Loch Ness target delivered to assay labs.
Six Sigma Metals Limited (“SI6” or “the Company”) is pleased to announce that the drill pads have been cleared and drilling of the high priority lithium target at Bonnyvale has commenced. Drilling is expected to be completed by the end of July and assay results to be returned in August.
Initial Drilling Program
As announced previously by SI6, an EIA report was completed for the initial drilling program at Bonnyvale and the Company mobilised expediently to ensure drilling commenced as soon as possible.
The initial drilling program will be conducted as a first pass to identify if lithium mineralisation continues at depth and will target the Bonnyvale pegmatite where 61 surface rock samples showed lithium mineralisation at levels over 2% Li2O (as announced on ASX 6 June 2018).
The drilling program will comprise 3 holes designed to intersect thick outcropping lithium-mineralised pegmatite as identified from surface rock samples (see ASX announcement 6 June 2018) and field investigations by the Directors of SI6. The area targeted by the 3 holes shows a prominent pegmatite body containing a long line of historic trenches and underground workings that display coarse-grained lithium host minerals such as spodumene, petalite and lepidolite.
The program aims to test the morphology, thickness and depth extent of the Bonnyvale pegmatite body.
Flexibility has been maintained to expand drilling program pending results.
ACQUISITION AND EXPLORATION UPDATE
- Option Agreement with Mirrorplex Pty Ltd has been amended:
- Consideration for Phase 1 (to Earn-In an initial 30%) has been modified, including a reduction of 25 million shares (50% reduction of the consideration shares for Phase 1 of the Earn-In); and
- Due diligence period has been extended to 116 days to allow for targeted exploration drilling to commence in July prior to SI6 electing to exercise the Option.
- An Environmental Impact Assessment has been completed over the Bonnyvale target area permitting SI6 to commence drilling beneath broad, high-grade lithium mineralisation.
- Drilling program to commence in July targeting a minimum of 3 holes. Flexibility to increase drilling scope pending results.
- The initial drilling program will be conducted as a first pass to identify if lithium mineralisation continues at depth and will target the Bonnyvale pegmatite where 61 surface rock samples showed lithium mineralisation at levels over 2% Li2O.
- SI6 fully funded to execute drilling program.
- New deal structure results in less dilution for shareholders of SI6 to earn-in to Phase 1 whilst maintaining the same exposure. In addition, the extension to the due diligence period allows SI6 to have a better-informed decision prior to exercising the Option under the Option Agreement.
The Board of Six Sigma Metals Limited (“SI6” or the “the Company”) is pleased to announce an amendment to the three-phased staged option agreement with Mirrorplex Pty Ltd (“Mirrorplex”) and the shareholders of Mirrorplex (“Vendors”) (“Option Agreement”), under which the Company can acquire up to an 80% interest in the Chuatsa Vanadium-Titanium and Shamva Lithium Projects in Zimbabwe (“the Projects”). SI6 and Mirrorplex have also completed an Environmental Impact Assessment (EIA) report and expects to be drilling in July a minimum of 3 holes to assess lithium potential at depth.
The accelerated drilling program will allow SI6 to further assess the lithium potential of the Projects before exercising the Option and committing to Phase 1 of the Option Agreement.
Variation of Option Agreement
SI6, Mirrorplex and the Vendors have agreed to a variation of the Option Agreement (announced on 17 May 2018) to modify the Earn-In Phase 1 consideration to be reduced to 25 million SI6 shares (previously 50 million SI6 shares) and increased by 25 million SI6 options (total 35 million options, previously 10 million options). The terms of the SI6 options have also been amended with an exercise price of 2.5c (previously 3c) and expiry 3 years from issue (no change to expiry).
In addition, SI6, Mirrorplex and the Vendors have agreed to extend the due diligence period on the Projects from 60 days to 116 days. This allows additional time for SI6 to accelerate exploration drilling and further assess lithium potential at depth prior to electing whether or not to exercise the Option.
The exploration funds expended by SI6 during the due diligence period will be included and incorporated into the work program for Phase 1 as valid expenditure by SI6 on the Projects in the event that the Option is exercised.
The Directors of SI6 are pleased with the outcome as it means less dilution for shareholders of SI6 to earn-in to Phase 1 whilst maintaining the same exposure. In addition, the extension to the due diligence period allows SI6 to have a better-informed decision prior to exercising the Option under the Option Agreement.
