Perth, Australia (ABN Newswire) - Horizon Minerals Limited (ASX:HRZ) is pleased to announce the commencement of drilling at the high grade Burbanks project, located approximately 9km to the south of Coolgardie in the heart of the Western Australian Goldfields (Figure 1*)

- Extensional and infill drilling has commenced at the high-grade Burbanks gold project, 9km south of Coolgardie in the Western Australian Goldfields

- Two phase RC and diamond drill programs for 30,000m planned:

o Phase 1 comprises ~15,000m of infill drilling to enhance resource continuity and confidence with results expected in the September 2025 quarter

o Phase 2 comprises ~15,000m of extensional drilling, targeting along strike and down dip of known high grade lodes

- Underground mining at Burbanks historically produced 324koz @ 22.7g/t Au

- The historical production is in addition to the existing JORC (2012) Mineral Resource of:

o 6.1Mt grading 2.4g/t Au for 466koz

- Infill and extension drilling in late 2023 intercepted significant mineralisation immediately down dip of historical high-grade intercepts with results including:

o 0.3m @ 45.40g/t Au from 428.1m (BBRC437D)
o 7.0m @ 5.51g/t Au from 130.0m (BBRC437D)
o 1.55m @ 20.43g/t Au from 301.0m (BBRC463D)
o 2.0m @ 11.79g/t Au from 425.0m (BBRC463D)

- Burbanks is expected to make a meaningful long-term contribution of high-grade ore feed to a refurbished Black Swan processing plant in the future

- The Black Swan PFS is scheduled for completion in the December quarter 2025

Commenting on the Burbanks drilling, Managing Director and CEO Mr Grant Haywood said:

"Past drilling at Burbanks has demonstrated the growth potential of this high-grade mineralised system both along strike and at depth. Our first phase of drilling will focus on transitioning more of the existing resource into the higher confidence JORC Indicated category to enable future conversion to an Ore Reserve and to progress this cornerstone asset towards being development ready. The second phase will then seek to deliver on the extensional potential seen in earlier drilling.

"As part of our strategy to become a standalone gold producer, we're undertaking a Pre-Feasibility Study to generate a five-year life of mine plan to feed our Black Swan processing facility, with Burbanks one of the key sources of high-grade mill feed for the plant. Refurbishment studies for Black Swan are being undertaken concurrently with the aim of first gold pour by the end of 2026."

The Company is focussed on becoming a standalone gold producer by refurbishing and repurposing it's Black Swan processing plant into a gold plant with a nominal throughput of 1.5Mtpa. Horizon is undertaking a Pre-Feasibility Study (PFS) to develop a five-year life of mine plan to fill the plant, and the Company believes that Burbanks will make a meaningful contribution of high-grade ore feed.

The Burbanks Project was acquired through the merger with Greenstone Resources Limited in June 2024. The project covers over 5km of strike in the highly prospective Burbanks Shear which historically is the most significant gold-producing structure within the Coolgardie Goldfield.

Project Geology

The Burbanks gold deposit is hosted by the high-Mg basalt and dolerite of the Burbanks Formation.

Alteration and several phases of metamorphism within the sequence has produced varying mineralogy, texture, and grain size within the mafic precursor, which historically has led to the description of gabbro and garnetiferous diorite as part of the host sequence. Five lithological units that comprise the host sequence are:

- Fine-grained amphibolite with a basaltic-doleritic appearance

- Coarse-grained amphibolite with a gabbroic appearance

- Gneissic amphibolite with a schistose to mylonitic texture

- Feldspar-amphibole and garnet gneiss with a dioritic appearance

- Quartz-veined zones

The above units are also intruded by two generations of later dykes into the sequence; one felsic and one mafic.

Mineral Resource Estimate (MRE)

There are several mineral domains within the Burbanks system, including Main Lode, Burbanks North, Burbanks South and Birthday Gift. The Burbanks MRE is summarised in Table 1*.

As can be seen from Table 1*, the majority of the resource is in the Inferred mineral resource category, with 31% of the open pit and only 10% of the underground resource in the higher confidence Indicated category. To bring in a larger proportion of the resource into the mine plan and provide for a higher conversion of the resource to an Ore Reserve, further infill drilling is required.

In addition, there is some information gaps in the metallurgical data for Burbanks, particularly in relation to comminution data that will be required for the PFS being undertaken by GR Engineering Services (GRES). This drilling program along with historical core will provide samples for this metallurgical testwork.

Drill Program

Previous drill programs completed in 2023 consisted of diamond and RC drilling successfully targeting down-dip and along-strike extensions to the known high-grade gold lodes, primarily in the upper 500m, and adjacent to the existing MRE. The historical workings only extend to 140m depth on the Birthday Gift lode, and 250m on the Main Lode. Previous drilling has confirmed the extension of the Main Lode ore body along strike and down plunge, with high-grade mineralisation identified more than 100 meters below historical workings. Additionally, the discovery of mineralised structures parallel to the main shear zone suggests a broader mineralised system, presenting opportunities for low-cost resource growth.

The Horizon geology team has reviewed the Burbanks deposit in detail, and has planned a ~30,000m drill program consisting of RC pre-collars with diamond tails. Drilling is programmed over two phases.

Phase 1 comprises 45 holes for ~15,500m and will concentrate on infill drilling either side of the Main Lode, towards the Birthday Gift and Burbanks North lodes to enhance resource continuity and resource confidence, and transition more of the resource from Inferred to Indicated. This will facilitate the generation of Ore Reserves and the development of a mining plan, essential steps for project advancement at Burbanks.

Guided by the Phase 1 results, the second phase of drilling will target down-dip and along strike extensions of known high-grade lodes, aiming to further expand and grow the resource base. The exploration strategy also includes targeting the projected extensions of the recently identified Burbanks North as well as parallel structures to the east.

Next Steps

Drilling is underway and initial results from Phase 1 are expected early in the September 2025 quarter.

Perth, Australia (ABN Newswire) - Horizon Minerals Limited (ASX:HRZ) is pleased to provide an update on the development of the Phillips Find ("Phillips Find") and Boorara ("Boorara") Gold Projects.

HIGHLIGHTS

Phillips Find

- Toll processing of the second stockpile of ore from the Phillips Find JV with BML (BML Ventures Pty Ltd) completed

- 18,676 dry tonnes of ore at 1.97g/t Au and 95.5% metallurgical recovery delivered 1,132.2oz sold at an average price of $5,140/oz, generating ~$5.8M in revenue to the Phillips Find JV

- First free cashflow distribution from the project achieved, generating ~$1.5M in net cashflow directly to Horizon

- An additional 87,000t of ore will be Toll Treated at the Greenfields Mill in August 2025, including 27,000t of ore from Boorara, to complete the Toll Milling Agreement with FMR

- The remaining 70,000t of ore from Phillips Find will be processed at Focus Minerals Limited's Three Mile Hill processing plant in September/October 2025 to complete this first phase of mining at Phillips Find

Boorara

- Significant ore stockpiles, comprising approximately 190,000 tonnes of high-grade and 126,000 tonnes of low-grade

- High-grade stockpiles being prioritised for treatment under the Ore Purchase Agreement (OPA) with Norton Gold Fields to treat at the Paddington Mill for the processing of a total of 1.24Mt of Boorara ore

- March 2025 quarter payments received from Paddington included 100% payment from the first stockpile and 50% for the second stockpile, yielding $6.3M in revenue

June Quarter Revenues

- June 2025 quarter to date, $12.8M in revenue received from Paddington, in addition to $7.5M received from FRM for the treatment of 51,228 dry tonnes at a grade of 0.92g/t Au and metallurgical recovery of 94.71% for 1,439.3oz sold at an average price of $5,195/oz treated at FMR Investments' Greenfields Mill

Commenting on the mining progress, Managing Director and CEO Mr Grant Haywood said:

"We are pleased that our haulage and processing activities are ramping up to crystallise the significant cash we have tied up within our ore stockpiles, with gold production and therefore revenue increasing significantly from the March quarter with both operations starting to build up cash flow."

Phillips Find

Mining at Phillips Find has progressed safely and productively with JV partner BML Ventures (BML) since October 2024 with first gold was poured in February 2025 under the first campaign.

The second campaign of Phillips Find ore has been processed at FMR Investments' Greenfields Mill near Coolgardie totalling 18,676 dry tonnes at a grade of 1.97g/t Au and 95.5% recovery. This yielded 1,132.2oz sold at an average price of $5,140/oz, generating ~$5.8M in revenue to the JV.

The second milling campaign occurred over a four-week period, with three weeks of processing Boorara ore and one week of Phillips Find JV ore. The JV partners have agreed to an early distribution of cashflow to Horizon from this Phillips Find campaign which comprised selling 300oz of JV gold at an average price of $5,060/oz, generating ~$1.52M in net cashflow directly to Horizon.

This earlier than scheduled payment is in part due to BML and Horizon renegotiating with FMR on the timing of milling for the benefit of BML, with the planned June 2025 campaign now occurring in August 2025. This will be a four-week campaign which would normally comprise one week of Boorara ore and three weeks of Philips Find ore, however due to the deferral of cash from June to August 2025, Horizon will treat for 10 days instead of seven in August 2025, and receive the early JV distribution of cash, which has already been received.

The August campaign will be the final processing at Greenfields under the 200kt agreement with FMR, with the remaining 70kt of Phillips Find ore being processed at Focus Minerals' Three Mile Hill plant in September/October 2025.

Boorara

Mining at Boorara has continued from Pit 2 (North) and Pit 4 (South) with ~190kt of high-grade ore stocks currently on the Boorara and/or Paddington ROM pads, and ~126kt of lower-grade ore stockpiled at Boorara. As anticipated, grades are improving in line with depth.

In addition to the treatment of Boorara ore at Paddington, a campaign was also processed through FMR Investments' Greenfields Mill near Coolgardie in April 2025 totalling 51,228 dry tonnes at a grade of 0.92g/t Au and a metallurgical recovery of 94.71% for 1,439.3oz sold at an average price of $5,195/oz, generating ~$7.5M of revenue to Horizon.

As previously reported, there was a hiatus in ore haulage to Paddington between ore parcel 1 and 2 whilst mining was undertaken through lower grade zones in the pits and as a result of time delays with the grade determination and the payment process.

Mining of high-grade ore has now achieved steady state and continuous ore haulage and processing is expected to continue to Paddington.

Revenues received in 2025 at Paddington have been $2.8M in January, $2.2M in February, $1.3M in March, $3.0M in April, $6.2M in May and $3.6M in the month of June to date, totalling $19.1M, broken down by stockpile below. This excludes the $7.5M revenue received from treatment at Greenfields received in May and June 2025.

Cost performance in the June half has been impacted by the establishment of stockpiles, lower than expected grade performance in the early stages of mining at Boorara and higher strip ratio. With continuous ore production and haulage now achieved at Boorara and grade control drilling at the operations well advanced, along with lowering strip ratios while grades improve, the operations are now well set-up for stronger cost performance and cash flow generation in the December half 2025.

Next Steps

The next campaign of ore treatment at FMR's Greenfields mill is scheduled to commence in early August 2025 and will comprise approximately 27kt of Boorara ore and 60kt of Phillips Find ore that completes Horizon's contract with FMR. The remaining 70kt of high-grade Phillips Find ore is scheduled to be processed in September/October 2025 through Focus Minerals' Three Mile Hill processing plant.

Mining, haulage and continuous treatment from Boorara shall continue at steady state through the Paddington plant.
