Manuka Targeting Near-Term Gold and Silver Production from its Cobar Basin Projects
On-site processing to underpin gold production at Mt Boppy, with optimised mine schedules and updated Reserves to support silver mining and processing at Wonawinta
The Mt Boppy Gold Mine is located within the prolific Cobar Basin of New South Wales. Since acquiring Mt Boppy in 2019, Manuka Resources Limited (ASX:MKR, the “Company”) has increased the Resource from 31,000 ounces of gold to 160,000 ounces (see Table 1 below) and produced in excess of 45,000 ounces of gold from ore that has been trucked to and processed through the 850,000tpa CIL plant located at Manuka’s Wonawinta Silver Project, approximately 150km south of Mt Boppy.
Highlights
- Manuka is the 100% owner of the Mt Boppy Gold Mine and Wonawinta Silver Mine, both located in the prolific Cobar Basin of western New South Wales.
- To date, ore mined by Manuka at Mt Boppy has been processed through the 850ktpa processing plant located at Wonawinta, some 150km south of Mt Boppy.
- Based on results received from the sonic-drilling program over the gold-bearing rock dumps and tailings at Mt Boppy, the Company has determined that the establishment of a fit-for-purpose, on-site crush-screen-mill-float-intensive cyanidation facility capable of processing approximately 200,000 tonnes p.a. will materially enhance the economics of the Mt. Boppy Mine and the value of near- mine prospects.
- Manuka anticipates the capital cost of the on-site processing facilities to be in the order of A$10-15M (annual ore haulage alone from Mt Boppy to Wonawinta would equate to ~50% of this capital cost). The processing facilities are scheduled to be installed, commissioned and producing gold dore in calendar Q4 2024. The Mt Boppy site is fully permitted for the proposed processing plant and on-site production.
- An updated Reserve and production plan for the Wonawinta Silver Mine (currently on care and maintenance) is targeted for release in May 2024.
Manuka’s Executive Chairman, Dennis Karp, commented:
“Mt Boppy has historically been one of the richest gold mines in New South Wales, having produced circa 500,000oz of Gold at 15 g/t. Indeed, since acquiring Mt Boppy in June 2019, production performance has largely exceeded our initial forecasts, notwithstanding the fact that we have processed Mt Boppy ore through the Wonawinta Processing Plant.
Our decision to transition to on-site processing at Mt Boppy will increase operational flexibility and deliver lower operating costs. We estimate that the savings in ore haulage alone will be in the order of A$6-7 million per year. The step-change in cost base supports a robust business case for the continued near-term processing of gold bearing rock dumps and tailings and deliver cashflows to fund aggressive brownfields exploration at Mt Boppy and at near-mine prospects such as Pipeline Ridge.
With gold and silver markets buoyant, we are excited by the immediate opportunity to re- establish ourselves as an ASX precious metals producer in the Cobar Basin, whilst progressing in parallel the development of our world-class Taranaki VTM Iron Sands Project in New Zealand.”
Background
Manuka completed a sonic-drilling program in December 2023 across the gold bearing rock dumps and dry tailings to improve confidence in grade distribution within the respective Resources and therefore the ability to selectively mine higher grade regions in each.
Based on positive preliminary results from the sonic drill program, Manuka has decided to progress an updated production strategy whereby a fit-for-purpose, 200,000tpa on-site crush- screen-mill-float-intensive cyanidation capability will be established on site at Mt Boppy.
Initial discounted cashflow calculations using the Mt Boppy updated production strategy and Wonawinta optimisation study supports the carrying amount of the Cobar assets as noted in the December 2023 Interim Financial Report.
The Company is currently in advanced negotiations to secure a process plant and anticipates the capital cost to be in the order of A$10-15M fully commissioned. The capital cost equates to less than 2 years of the current cost for transporting ores from Mt Boppy to Wonawinta at the proposed rate of production. The Mt Boppy site includes an existing 48-person mining camp, power and water, administration office, exploration office and is permitted for the processing plant and on-site production.
Manuka aims to be producing gold dore from the new plant at Mt Boppy by Q4 2024.
Table 1: Mt Boppy Resource Estimate1
Wonawinta Silver Mine Update
A dedicated processing facility at Mt Boppy will allow for dual revenue streams by freeing up the Wonawinta processing plant to process ore from the Wonawinta Silver Mine (currently on care & maintenance) and associated stockpiles.

Norfolk Metals: ASX-listed Uranium Explorer
Norfolk Metals (ASX:NFL) focuses on uranium exploration in South Australia and Argentina. The company advances its flagship Orroroo uranium project with a recent maiden drill program that intersected a uranium-bearing floodplain, boosting confidence in the potential of the project.
The Orroroo uranium project consists of three exploration licenses - EL6552, EL6814, and EL6948 - spanning a total of 723 square kilometers, situated roughly 274 kilometers northwest of Adelaide, South Australia. The large land holding is divided into three project areas named Orroroo, Johnburgh and Black Rock.
As it continues to review complementary projects with plans to expand its uranium project suite, Norfolk signed an exclusivity agreement with Green Shift Commodities (TSXV:GCOM) to acquire Las Alteras uranium project in Argentina. Las Alteras is surrounded by non-JORC foreign estimates at URAmerica’s Meseta Central deposit (19.1 Mlbs U308), CNEA’s Cerro Solo deposit (11.49 Mlbs U308), ISO Energy’s Laguna Salada deposit (10.1 Mlbs U308), along with the Cerro Condor and Los Adobes historical uranium mines.
Company Highlights
- Norfolk Metals is an ASX-listed uranium-focused explorer with assets located in South Australia (Orroroo uranium project), Argentina (Las Alteras uranium project) and Tasmania (Roger River gold/copper project).
- The primary focus is on advancing the Orroroo uranium project located in the Walloway Basin in South Australia. Orroroo comprises three granted exploration licenses, which together cover 723 square kilometres. of contiguous tenements. The land holding is divided into three project areas named Orroroo, Johnburgh and Black Rock.
- Orroroo has geological similarities to well-endowed South Australian uranium producers such as Boss Energy’s Honeymoon Uranium project and Heathgate Resources’ Four Mile mine.
- Norfolk completed a maiden drill program at Orroroo which delineated uranium in 10 of the 17 holes with grades reaching as high as 796 ppm. The maiden drill program also identified a uranium-bearing floodplain 50 meters south of the Wongway Creek Target.
- In Argentina, Norfolk has signed an exclusivity agreement with Green Shift Commodities to acquire Las Alteres uranium project, a project surrounded by multiple uranium deposits and historical mines in every direction including the Cerro Solo government owned deposit
- The Roger River Project comprises two granted exploration licenses, which together cover 261 square kilometers, located in Tasmania. The project is prospective for gold and copper.
- Norfolk is evaluating other projects for acquisition, which includes complementary projects to the South Australian uranium project suite.
- Uranium prices are likely to remain firm on the back of supply deficit. Kazakhstan, the world’s largest uranium supplier, has warned of lower production in 2024, while demand continues to remain high as governments around the world embrace nuclear power to reduce reliance on fossil fuels.

Manuka Resources March 2024 Quarterly Activities Report
Manuka Resources Limited (“Manuka” or the “Company”) is pleased to provide the following report on its activities during the quarter ending 31 March 2024.
HIGHLIGHTS
During the Quarter
- The Company investigated the economic and strategic benefits of establishing fit-for-purpose ore processing and gold doré production facility at Mt Boppy.
- Accordingly, the transporting to, and processing of, Mt Boppy ore through the Company’s Wonawinta plant, located 150km south, was placed on hold.
- Results from a sonic drilling program were received improving the confidence level of the Mt Boppy Resource and supporting the development of a longer term mine plan.
- Income from the sale of 201oz gold and 2,487oz silver recovered from Mt Boppy ore, together with funds of A$3.9 million received from a combination of placement and SPP, were used to offset costs associated with the ramp-down of operations and working capital requirements.
Post Quarter End
- The Company announced the results of its Mt Boppy investigations outlining an A$11.6M upfront capital cost and an initial 5-year mine plan to deliver an average EBITDA of A$19M per annum commencing Q4 20241.
- The mine plan was supported by an upgrade in the Mt Boppy Resource which saw Measured and Indicated Resources increase to 82% of the total Resource2.
- The Company received A$1.1M from an application made under the Australian Government’s R&D tax incentive scheme for a successful process improvement program undertaken to enhance silver production at Wonawinta. The Company is targeting the release of an updated Reserve Statement for Wonawinta as a standalone silver operation during the current quarter.
- The Company was specifically invited to submit an application for the world-class Taranaki VTM Iron Sands Project to be included as a Listed Project within New Zealand’s Fast Track Consenting Bill, legislation to streamline decision making and facilitate the delivery projects with significant regional or national benefits.
Dennis Karp, Manuka’s Executive Chairman, commented:
“The March quarter has been one of transition and one that has seen the Company decisively pivot its strategy toward a staged, self-sustaining growth plan.
Manuka Resources is uniquely positioned amongst its ASX peers to leverage buoyant gold and silver markets. In the Mt Boppy and Wonawinta mines, we have a low capex pathway to deliver near term gold and silver production and free cashflow to fund exploration, Resource growth and mine life extension.
Looking further ahead, the invitation to apply for inclusion as a Listed Project within New Zealand’s Fast Track Consenting Bill provides line of sight on the progressing of our world-class Taranaki VTM Iron Sands Project
We are looking forward toward the next quarter and next 12 month with great optimism and confidence that our strategy will deliver results for our shareholders.”

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
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.
