- Two diamond drill holes planned, totalling 400m, testing for extensions to high-grade gold veins sampled in the historical Golden Ridge Adit between the Brilliant and Trafalgar prospects
- Previously reported underground sampling in the adit recorded high- grade gold assays including 64.4g/t Au, 37.6g/t Au and 15.9g/t Au
- Flynn Gold to receive up to $70,000 under the Tasmanian Government’s Exploration Drilling Grant Initiative (EDGI) to co-fund this drilling program
- For further information or to post questions go to the Flynn Gold Investor Hub at https://investorhub.flynngold.com.au/link/lyazve
This new drilling program will test beneath the historical Golden Ridge Adit, where recent underground sampling of veins recorded results of up to 64.4g/t gold1. The adit is located in the Link Zone prospect area, situated between the Brilliant and Trafalgar prospects at Golden Ridge.
Flynn Gold Managing Director and CEO, Neil Marston commented:
“We are delighted to have commenced our latest drilling program at the Golden Ridge Project in north-east Tasmania.
“This drilling program, which is co-funded under the State Government’s Exploration Drilling Grant Initiative, will see Flynn Gold drilling at the Link Zone beneath the historic Golden Ridge adit, where sampling of mineralised veins earlier this year yielded grades of up to 64 g/t gold.
“This diamond drill program is the first to test this adit, which lies between the historic Brilliant and Trafalgar mines – where we have successfully focused our drilling to date.”
Golden Ridge – Project Background
The Company’s flagship Golden Ridge Project is situated within EL17/2018 in North-east Tasmania (see Figure 1).

Tartana Positive Metallurgical Copper Testwork
Highlights:
- Tartana D15 assays confirm broad zones of copper mineralisation including 76 m @ 0.60% Cu, 178 m @ 0.40% Cu or 221 m @ 0.35% Cu, all from 31 m depth downhole.
- Excellent copper recoveries (89%) to saleable copper concentrate when testing a sample that was below the resource grade average.
- Bulk Sample Tomra ore sorting results indicate that using this process will result in a 72% grade increase and recover 71% of the contained copper.
- Mineralisation trends indicates the presence of a higher grade zones (1 million tonnes @ 0.82% Cu) enabling the potential for a high grade starter pit with the remaining resource at 8.5 million tonnes @ 0.38 % Cu which can be upgraded if required.
- The results form part of a Scoping Study which will investigate options for third party processing and/or installation of a copper sulphide crushing, milling and flotation plant or a combination of both. This is separate from the current copper sulphate pentahydrate production which is ongoing.
The hole was successfully completed on 13th May 2024. The assay and metallurgical data have now been received and as discussed below, have returned positive results which can be incorporated into a Scoping Study which will also consider processing options. These options include third party processing and/or installation of a copper sulphide crushing, milling and flotation plant and which may be a combination of both.
Tartana Primary Copper Mineralisation
The Company has previously advised the presence of primary copper (chalcopyrite) mineralisation below the Tartana pit floor and in early 2023 reported 45,000 tonnes of contained copper resource to 130 m depth (see ASX release dated 9 February 2023). The details are outlined in Figure 1.
Figure 1. (a) Oxide, transitional and primary (fresh) resource estimation for the Tartana open pit using inverse distance estimation and a 0.2% Cu cutoff grade. (b) Primary copper mineralisation from drillhole D15.
The resource grade and tonnage for the total primary and transitional resources at different cut-off grades are presented in Figure 2.
Figure 2. Transition and primary resources at different cut-off grades (Reported 9th February 2023)
The Company has designed a drilling programme with a target of increasing the current resource to greater than 100,000 tonnes of contained copper which includes drilling to test mineralisation below 130 m depth and also shallower mineralisation on the periphery of the resource.
However, prior to embarking on this drilling campaign, in May 2024 the Company drilled a metallurgical test hole (D15). This was a diamond hole drilled with large diameter core commencing with PQ size and then reducing to HQ core to increase the recovered core sample. It was drilled to 300 metres depth and was drilled parallel and below TRC098 which had previously intersected 77 m @ 0.62% Cu although D15 was drilled beyond the edge of the existing resource. The purpose of the hole was to:
- Test mineralisation trends including continuity downdip from TRC098 and other nearby holes and beyond the existing resource.
- Check assay grade variability between chips from the earlier RC drilling and diamond drill core.
- Inspect geological features such as lithologies, bedding trends and structural logging.
- Provide an adequately sized sample for flotation and recovery testwork to produce a saleable copper concentrate.
- Provide a large bulk sample for testing for Tomra ore sorting
The hole was successfully drilled and completed on 13th May 2024. An outline of the findings is presented below.

Horizon Minerals
Investor Insight
Horizon Minerals’ near-term cash-flow potential and its significant land package in the prolific Western Australian goldfields with considerable exploration upside position the company to positively leverage the current bull gold market opportunity.
Overview
Horizon Minerals (ASX:HRZ) is an ASX-listed emerging mid-tier gold mining company focusing on a portfolio of highly promising gold projects located in the world-class Western Australian goldfields. The recent merger with Greenstone has added nearly 0.5 million ounces (Moz) of high-grade resource to Horizon, taking its total tally to 1.8 Moz, and resulted in Horizon Minerals total land package of 939 sq km in the Kalgoorlie-Coolgardie district.
The merger brings near-term cash-generating opportunities and adds greater scale to its baseload assets (Boorara) with the high-grade Burbanks deposit. Horizon’s dual-track strategy involves generating immediate cash flows by leveraging a pipeline of development-ready production assets and concurrently advancing the cornerstone assets, Boorara and Burbanks, which have a combined resource inventory of 914 koz at 1.7 grams per ton (g/t) gold with potential to support a profitable, long-life operation.
The recent ore sale agreement with Paddington Gold is encouraging and increases confidence in the management’s ability to generate near-term cash flows. Under the agreement, 1.4 million (Mt) will be processed over a period of 22 months. The agreement allows Horizon to capitalize on high gold prices to generate significant cash flows.
Horizon is also progressing with other projects, including the Cannon gold project and Penny’s Find underground mine, and actively exploring for new discoveries in the Western Australian Goldfields, targeting gold and other commodities such as nickel-cobalt, silver-zinc, PGEs and lithium across its extensive land holdings. Additionally, Horizon holds a significant stake in one of the world’s largest vanadium projects via its investment in Richmond Vanadium Technology, which is listed on the ASX.
Horizon proposes to acquire 100 percent of Poseidon via an all-scrip transaction for AU$30 million to consolidate 1.8Moz gold and highly strategic processing infrastructure for Horizon to transition to the next standalone WA gold producer. The acquisition will combine Horizon’s large gold resource and Poseidon’s Black Swan processing infrastructure in the Kalgoorlie-Coolgardie districts. The transaction will further result in substantial resource base and regional tenure to a combined JORC mineral resources of ~1.8Moz gold at an average grade of 1.84g/t gold and 422,700t nickel at an average grade of 1 percent nickel. Horizon and Poseidon will have a total of 1,309 sq. km. tenure in an attractive geological position in the WA Goldfields.
Horizon aims to become a sustainable, 100kozpa standalone producer following the merger and conversion and recommissioning of the Black Swan processing plant. The 2.2Mtpa processing facility is strategically located 40 km north of Kalgoorlie with a concentrator readily amenable to processing gold through cost-effective refurbishment and the addition of a new CIL circuit.
Horizon's 30Mt existing gold resources, with 50,000 metres of drilling fully funded to commence drilling in 2025 or 2026, strongly support the conversion of the Black Swan processing plant to a gold plant.
Company Highlights
- Horizon Minerals is an emerging mid-tier gold producer with an extensive portfolio of highly promising gold projects located in the world-class Western Australian goldfields.
- The recently announced merger with Greenstone Resources positions Horizon as a mid-tier gold producer in the Western Australian Goldfields. The combined entity enhanced Horizon’s portfolio with two complementary cornerstone gold assets — Burbanks and Boorara (combined resource of 914,000 oz).
- Mineral resource updates after the merger include 1.8Moz gold, 20.2Moz silver, 104kt zinc, 283kt nickel, 40.5kt cobalt and 296.2kt manganese.
- Changes to the gold MREs include:
- Addition of 297,650oz from Burbanks open pit
- Addition of 167,920oz from Burbanks underground
- Addition of 13,000oz from Pinner
- Addition of 3,000oz from Monument
- Reduction of 20,240oz from Boorara
- Open pit mining has commenced at the Boorara gold project on August 2024 and the first ore was exposed and mined in late September 2024.
- Horizon is also progressing with other projects, including the Cannon and Penny’s Find underground mines.
- Amidst the current record gold prices, Horizon seeks to capitalize on this opportunity by advancing its substantial resource endowment towards development, thereby generating cash flow.
Key Projects
Boorara Gold Project
The Boorara gold project is located 15 km east of Kalgoorlie-Boulder in the Western Australian goldfields. Over the past decade, a substantial amount of reverse circulation and diamond drilling has been carried out at Boorara. The project includes a JORC 2012 mineral resource estimate (MRE) by Optiro (now Snowden Optiro), which reported a total of 11.03 Mt grading at 1.26 g/t gold, amounting to 448,000 ounces.
The company views Boorara as a substantial baseload feed source that could be enhanced by lower tonnage, higher-grade feed to sustain a standalone milling facility. This is where the recent acquisition of Greenstone becomes important. Boorara can be supplemented by higher-grade feed from Greenstone’s Burbanks deposit to support an integrated operation.
The Independent JORC (2012) Ore Reserve for Boorara, completed by AMC Consultants, shows a financially viable project highlighted by an open pit mine design producing 1.24 Mt at a fully diluted grade of 1.24 g/t gold for 49.5 koz over an approximate 14-month mine life, and ore sale agreement at 92.5 percent metallurgical recovery produces 45.8 koz recovered.
Boorara commenced open pit mining in August 2024, with the first ore exposed and mined in late September 2024. Mining at the site will occur over 14 months and processing over 19 months at Norton Gold Fields’ Paddington plant to generate $30 million in estimated free cashflow at a AU$3,600/oz gold price.
Nimbus Silver-Zinc Project
The 100 percent owned Nimbus silver-zinc-lead-gold deposit is located 15 kilometres east of Kalgoorlie-Boulder in Western Australia within the Kalgoorlie Terrane. The project's current mineral resource estimate (JORC 2012) includes 12.1 million tons at 52 g/t silver, 0.2 g/t gold and 0.9 percent zinc containing 20.2 million oz of silver, 78,000 oz of gold and 104,000 tons of zinc using lower cut-off grades of 12 ppm for silver, 0.5 percent for zinc and 0.3 g/t for gold over a 2 metre down hole composite. Within this global resource, the Nimbus project has a high-grade silver and zinc resource of 255,898 tons at 773 g/t silver and 13 percent zinc.
A concept study has confirmed the optimal economic development pathway by mining the higher-grade lodes and generation of a silver/zinc concentrate. A programme of work (POW) has been approved and drilling to test the exploration target is expected to be undertaken in the first half of 2025. The Nimbus project is 2 km east of Horizon's cornerstone Boorara project and 6.5 km north-northwest of Golden Ridge, both historic gold mining centres.
Burbanks Gold Project
The Burbanks gold project is situated 9 km southeast of Coolgardie, Western Australia. The project encompasses the Burbanks Mining Centre and more than 5 kilometers of the highly promising Burbanks Shear Zone, historically the most significant gold-producing structure within the Coolgardie Goldfield. Previous underground production at Burbanks has surpassed 420,000 oz to date.
Burbanks currently hosts a total resource of 6.1 Mt @ 2.4 g/t gold for 466 koz, including underground of 1.2 Mt @ 4.4 g/t gold for 168 koz. Burbanks is underexplored and remains open in all directions for future growth.
Cannon Underground Project
The Cannon gold project is located 30 km east-southeast of Kalgoorlie-Boulder. It is a fully permitted project with a pre-feasibility study completed in 2022, which shows strong project economics with a free cash flow of AU$10.1 million over the mine's life. The company has finished commissioning a dewatering pipeline and a pumping system, representing a major milestone in the advancement of its Cannon Underground project. Discussions with mining contractors and potential JV mining partners are underway. First ore production from the Cannon Project is expected to commence in Q4 2024.
Penny’s Find
Penny’s Find is about 50 km northeast of Kalgoorlie in the Eastern Goldfields of Western Australia, near the company’s wholly-owned Kalpini gold project. It comprises a granted mining lease and other associated leases covering 91 hectares. The mineral resource estimate updated in December 2023 boasts 63,000 ounces of gold in the indicated and inferred category. A pre-feasibility study for exploitation using underground mining methods is currently underway. This study will include mine design and financial analysis.
Rose Hill
Rose Hill is 0.5 km southeast of Coolgardie and 35 km west of Kalgoorlie-Boulder, on the western edge of the Archean Norseman-Menzies Greenstone Belt. The current JORC 2012 resource at Rose Hill contains 93,300 oz , comprising an open-pit mineral resource of 0.3 Mt grading 2.0 g/t gold for 18,400 oz, and an underground mineral resource of 0.5 Mt grading 4.6 g/t gold for 74,900 oz. Nearly 70 percent of the resource is in the measured and indicated JORC categories.

Cadia is Newmont's first site globally to receive the award after successfully meeting more than 30 criteria needed in critical areas including environment, community, human rights and governance, amongst others.
Newmont's Cadia mine is the nation's second largest copper producer and the third site in Australia to receive The Copper Mark. Cadia is the only operating mine producing molybdenum in Australia and thus the only mine to receive The Molybdenum Mark, a critical mineral used in industry and defense.
Newmont Chief Safety and Sustainability Officer Suzy Retallack said, "Meeting growing global demand for copper brings an obligation to sustainability and responsible mining which prioritises environmental stewardship, social responsibility and economic development for the communities in which we operate."
"We take great pride in being at the forefront of the copper industry with The Copper Mark, which highlights our dedication to responsible production and transparency," she said.
"This means our global customers can now choose to source copper concentrate from an independently evaluated mine that meets the highest standards in environmental, social, and governance practices, responding to the increasing demand for sustainable supply chains."
In 2020, Cadia entered into a 15-year renewable Power Purchase Agreement (PPA) with Tilt Renewables Limited to buy 55% of the wind farm's output. Now fully operational, Rye Park is supplying approximately half of Cadia's power needs.
"Cadia's commitment to the community supported an investment of almost $6 million AUS in the 18 months to December 2023 to support community projects, education and infrastructure," Retallack said.
The Copper Mark's Executive Director Michèle Brülhart said, "Congratulations to the team of Cadia for being the third site in Australia to achieve The Copper Mark and the first site to get The Molybdenum Mark. With this, about 35% of Australia's copper is produced at sites that have obtained The Copper Mark."
The Copper Mark is the leading assurance framework to promote responsible, sustainable and ethical practices across the copper, molybdenum, nickel and zinc value chains.
Cadia is located approximately 16 miles (25 kilometres) south-southwest of Orange in Central West New South Wales (NSW) and 250 kilometres west of Sydney, and comprises the Cadia East underground mine, which is one of the largest gold and copper deposits in the world, and Ridgeway Underground Mine, currently in care and maintenance.
