Drilling Update at Mt York, Pilbara WA
October 09, 2022
First hole intercepts pegmatite at Lucky Sump Prospect plus wide zones of silicification-sulphide hit in core drilling to extend resource
Kairos Minerals (ASX:KAI) owns 100% of the flagship 1.1 Mozs Mt York Gold Project that was partially mined by Lynas Gold NL between 1994 and 1998. Pre-feasibility work is progressing rapidly underpinned by a +20,000m diamond and RC drilling campaign to collect important information for further resource expansion, metallurgical testwork, mining and process engineering to determine viability and optimal pathway to develop a sustainable, long-lived mining project. Current resources at a 0.7 g/t Au cutoff grade are shown in the table below.
Highlights – Lucky Sump
- First hole drilled at Lucky Sump (KMY216) intercepted 5m of pegmatite; Assays pending
- Pegmatite intervals of 2-3m drilled in two other holes at Lucky Sump
- In light of these results, further RC holes are being planned at Lucky Sump and at Zakanaka, 2km north of Lucky Sump
- RC samples will be sent for multi-element analysis to determine lithium grade and Hylogger-3 for mineralogy
Highlights – Mt York Gold Project
- Sulphide zones intercepted in all diamond drill holes, extending and expanding interpreted mineralised zones
- Spectacular wide and significant sulphide-silicified zones drilled outside of current resource envelope at Main Hill (KMYD070)
- Nine dimond holes for 2,844m completed in the 89-hole programme
- Core cutting and sample preparation to begin this month
Kairos Managing Director, Dr Peter Turner said: “We have made a highly promising start to our first lithium drilling programme, successfully intersecting pegmatites at Lucky Sump. We eagerly await both the mineralogical assessment and laboratory analyses of the samples. New planned holes at Lucky Sump and Zakanaka will be drilled upon receipt of the lithium assays from the initial programme.
“At our flagship Mt York Gold Project, drilling has intersected spectacularly wide silicified- sulphide zones within the mine stratigraphy in both hangingwall and footwall positions to the main mineralised banded iron formation.
“We expect to continue seeing very thick sulphide-silicified zones known to be associated with mineralisation outside the current resource estimate as we have just seen in hole KMYD070, because this deposit is very much untested by drilling.
“We feel extremely confident that our targeting strategy based on 3D modelling and structural interpretation will extend the mineralisation significantly beyond the current 1.1 Mozs resource in preparation for the prefeasibility study”.

Quarterly Activities Report for Period Ended 31 March 2024 and Appendix 5B
Tartana Minerals Limited (ASX: TAT) (the Company) is pleased to announce that it has achieved several milestones during the March quarter and in April 2024. With the refurbishment of the solvent extraction – crystallisation plant in 2023 the Company produced its first 28 bag shipment of Copper Sulphate Pentahydrate (Copper Sulphate) and which has been sold to Kanins International, our offtake partner.
Highlights:
- The Copper Sulphate Pentahydrate plant is continuing production and achieving its first sale;
- Purchase of a new 3 Deck Kason Vibroscreen Separator to further increase production quality;
- Standard Conduct and Compensation Agreement signed with landholder on the Maid EPM 27735;
- Dr Alistair Lewis appointed to the Board;
- Major subsequent events including:
- $1.8 million raised including $1.7 million of new capital beyond Rights Issue subscriptions from shareholders – with $1.5 million of that amount being at $0.05 and the balance $0.3 million being a loan.
- Name and ASX code change completed to Tartana Minerals Limited (ASX:TAT) and corporate rebranding including a new website www.tartanaminerals.com.au
As previously reported, it has been a difficult and long wet season with access to the mine restricted by high river levels in the Walsh River which had closed the Burke Development Road for several weeks. With accessibility having been restored, the mine is receiving diesel and acid supplies, and ongoing production is targeting the second 28-bag (34 tonne) shipment. The new Kason vibrating screen and other modifications are expected to improve plant performance and reliability.
Elsewhere, the Tartana Copper resource has an existing open pit resource to 130 m depth comprising of 10.039Mt @ 0.45% Cu for 44,781 tonnes of contained Copper using a 0.2% Cu cutoff grade as reported to the ASX on 9th February 2023. While the average grade increases by increasing the cutoff grade above 0.2% Cu, the Company believes a better solution is ore sorting, which has the potential to lift an average ore feed grade above 1% Cu and also minimises the open pit strip ratio.
Further, a Standard Conduct and Compensation Agreement (CCA) has been finalised with the landholder on the Maid EPM 27735. This CCA extends from 1 May 2024 through to 31 December 2025 and relates to proposed exploration activities including drilling regional prospects within EPM 27735, whilst excluding activities related to Tartana’s existing Mining Lease Applications at Cardross and Maid which lie within the surrounding EPM 27335 area.
The Company has also raised $1.82m including $0.3m in a new convertible note and the Rights Issue Shortfall Placement. This places the Company on sound financial footing with Copper Sulphate production expected to provide ongoing cash flow.
Copper Sulphate Production
While plant commissioning commenced last October and progressed through November, the onset of the extended wet season in December led to a slow start to production this year. This stems from high water levels in the Walsh River, which blocked access to the mine northwest of Chillagoe. In particular, it prevented the delivery of reagents, including sulphuric acid and diesel, to the mine site.
Production recommenced in April, with the completion of the first shipment of 28 bags (34 tonnes), and the completion of the second shipment is expected soon. Copper is being sourced from the ponds, which hold an estimated 96 tonnes of Copper in solution, and which equates to more than 300 tonnes of Copper Sulphate, assuming 80% recovery. Copper will then be sourced from the heaps, which contain an estimated 1,364 tonnes of Copper (as reported to the ASX on 22 July 2022), before the Company is to address the mining of remnant oxide and transition ore.
Additional LIX for the solvent extraction has been ordered and is expected to increase daily production to the forecast 6-8 bags per day. Combined with an additional roster, it will significantly increase production.
Plant reliability is improving, and the Company is recovering from both the challenges of the wet season and the deterioration of equipment such as the screen. The Company has purchased a new 3 Deck Kason Vibroscreen Separator from DTD Engineering, which will improve the product, enabling the sale of Tartana copper sulphate to premium markets with stricter product requirements. The bag scales are also being repaired to ensure constant bag weights.

Background
Siren is a New Zealand focussed gold and antimony explorer, with two key projects in the upper South Island of New Zealand: Reefton (Reefton, Lyell and Paparoa goldfields) and Sams Creek (Figure 1).
The Reefton Goldfield produced ~2Moz of gold at an average recovered grade of 16g/t from 84 historic mines, plus an estimated alluvial gold production of 8Moz. Most underground mining ceased by 1942, with the famous Blackwater mine closing in 1951, when the shaft failed, after producing ~740koz of gold down to 710m below surface.
OceanaGold Limited (OGL) developed an open pit on the historic Globe Progress mine between 2007 and 2015. OGL recovered an additional 700koz at around 2g/t Au, increasing total hard rock production at Reefton to around 2.7Moz @ 12g/t Au.
Federation Mining Limited (FML) a privately owned company, is currently developing the Snowy River Mine on the Birthday Reef (Figure 2), which historically produced 740koz of gold at an average recovered grade of 14.2g/t.
Sams Creek is a gold mineralised porphyry dyke, the extends for 7km and is up to 60m thick. The Sams Creek Dyke (SCD) was discovered in 1974 and has not been historically mined. The Main Zone and Anvil projects are contained within an Exploration Permit (EP40338) that is part of a Joint Venture between Siren (81.9%) and New Zealand’s largest gold miner, OceanaGold (TSX:OGC), which holds the remaining interest (18.1%).

Figure 1 – Comet Vale Project location, WA
COMET VALE
During the quarter, significant focus has been placed on the divestment of Labyrinth Gold Project in Canada. Meanwhile, targeting and planning of exploration activities is well underway at Comet Vale. Strong performance in the gold price this quarter shows no signs of slowing, bolstering Labyrinth’s interest in Comet Vale Gold Project. With gold and base metal potential still high, the Company is leaving no stone unturned in finding suitable drill targets to truly test the potential.
LRL has previously announced the commitment to refocus exploration activities at Comet Vale Project near Menzies, Western Australia. The project is a joint venture project between Labyrinth (51%) and Sand Queen Gold Mines Pty Ltd (49%). In 2023 an updated Mineral Resource Estimate was completed on the Comet Vale Underground (‘UG’) and Open Pit (‘OP’) historic resource (see Table 1 and 2)6. Figure 2 demonstrates the substantial Resource growth potential of the currently only shallowly defined Sand George mineralisation.

Arbitration Award for Antilles Gold’s Subsidiary
Antilles Gold Limited (“Antilles Gold” or the “Company”) (ASX: AAU, OTCQB: ANTMF) advises that an Award has been issued by the Tribunal of the International Centre for Settlement of Investment Disputes (“ICSID”) which conducted Arbitration proceedings to determine several Claims by wholly owned subsidiary, EnviroGold (Las Lagunas) Limited (“EVGLL”), against the Government of the Dominican Republic (‘the Government”, or “the State”).
The Claims relate to the Las Lagunas Gold Tailings Project which involved EVGLL recovering approximately 5.0 million tonnes of 3.5g/t gold tailings stored in a dam at Las Lagunas in the Dominican Republic, which originated from the adjacent Pueblo Viejo mine, and then oxidising the toxic sulphide tailings before producing a gold dore for refining overseas, and the sale of bullion.
The Project operated from July 2012 to December 2019, and was carried out under the terms of a Contract between EVGLL and the State dated 28 April 2004.
ICSID, which is based in Washington DC, and is a Unit of the World Bank, has been conducting the Arbitration through a three-member Tribunal established on 5 August 2020. The Award was issued on 24 April 2024, and received by EVGLL on 25 April 2024 following a final hearing in early June 2023.
EVGLL has been awarded US$4,070,283.85 (~A$ 6,308,940 at an exchange rate of A$1:00 = US$0.65) including interest to 24 April 2024. Simple interest continues to accrue at 7.3% pa.
The attached “Review Of Arbitration Award” details the Claims made, and the reasons for certain adverse decisions by the Tribunal which are perplexing, and in the Company’s view, unreasonable.
The result is disappointing, and is primarily as a result of the Tribunal rejecting EVGLL’s principal Claim of US$15.5 million for additional costs, and reduced gold production that resulted from the State’s failure to meet its contractual obligation to provide a site for the construction of a tailings storage facility into which reprocessed tailings could be deposited.
As a consequence, the reprocessed tailings had to be redeposited back into the Las Lagunas Dam behind substantial rock retaining walls at a considerable cost.
The Tribunal found that EVGLL had preferred to redeposit the reprocessed tailings back into the Las Lagunas Dam, and despite acknowledging the State’s breach of contract, ruled that EVGLL had effectively waived the State’s obligation to provide a site for the construction of a new dam.
In the opinion of the two Executive Directors of EVGLL involved in the Project, the Tribunal failed to take into account, or believe, their sworn Witness Statements, and oral testimony which reinforced EVGLL’s rights, and commitment to build a new tailings dam had the site been provided by the State.
A positive element of the Award was the Tribunal ordering the State to compensate EVGLL for the State’s breach of EVGLL’s entitlement to a special compensatory and fiscal regime, and to lift illegal garnishments that have prevented EGVLL from selling plant and equipment stored at Las Lagunas since October 2019, and to not reimpose them.
This will allow EVGLL to sell approximately A$3.0 million to A$4.0 million of surplus assets. While the State was directed to reimburse EVGLL for the Jurisdictional Phase of the Arbitration settled in EVGLL’s favour on 31 March 2022, the Award in relation to legal costs for the Merits
Phase of the Arbitration is based on EVGLL having to pay for 86% of the total of both parties legal costs, after winning only 14% of the total amount of its Claims. EVGLL will reimburse the State ~US$1,500,000 of its legal costs, plus simple interest accruing at 7.3%pa.
The A$6.3 million awarded to EVGLL is expected to be received in the near term, and will assist the Antilles Gold Group to fund the outstanding US$2.0 million of its farm-in to a 50% shareholding in Cuban joint venture company, Minera La Victoria, and the development of its first project, the Nueva Sabana gold-copper mine.
The Chairman of Antilles Gold, Mr Brian Johnson, commented that“the Tribunals’ reasons for rejecting the main Claim are difficult to comprehend, but there is no right of appeal. The Company would not have expended so much time and money on arbitration of this Claim if the Board, and its legal advisors had not thought it to be both genuine, and justified.
EVGLL will collect its entitlement to A$6.3M, and the Group will move on with its projects in Cuba.”
