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 Greenstone 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.

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 10.53 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.
Phillips Find Gold Project
The Phillips Find gold project is located 45 km north-west of Coolgaride, Western Australia in the heart of the Western Australian goldfields covering 10 kilometres of strike over prospective greenstone stratigraphy. The project includes the Phillips Find Mining Centre (PFMC) where approximately 33,000 ounces of gold were produced between 1998. A joint venture (JV) agreement is in place with mining specialists BML Ventures Pty Limited (BML) to develop and mine two open pits at Phillips Find. Horizon Minerals plans to commence the grade control program early in December and the first mining of ore in December 2024. The first ore from Phillips Find is on track to be treated at FMR’s Greenfields mill from February 2025 to June 2025
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.
