Targeting High-Grade Gold in Western Australia's Murchison Region
Breakthrough Minerals gold exploration has commenced at its 100% owned Errolls Gold Project in Western Australia's Murchison Region, marking a swift transition to active operations following the project's acquisition.
The company has initiated a soil sampling program focused on the western magnetic trend that parallels the Youanmi Shear Zone, with drilling expected to begin in early August once final approvals are secured.
The upcoming drilling program aims to follow up on previously identified shallow high-grade gold mineralisation, including spectacular intercepts of 22m @ 7.46g/t Au from surface (including 5m @ 31.76g/t Au) and 11m @ 6.88g/t Au from 14m (including 6m @ 12.3g/t Au).
"We are delighted to be underway with fieldwork at the Errols Gold Project, wasting no time at all following the completion of the acquisition to getting boots on the ground. The exploration team has a wealth of historical data to guide the field program and we are excited to start to build our understanding of this highly prospective asset." – Executive Director Peretz Schapiro
Dual-Focus Drilling Strategy Targets Known Mineralisation and New Areas
The Errolls exploration program features a strategic two-pronged approach:
- Southern Extension Exploration: Targeting the extension of known mineralisation at the Errolls Legacy Prospect
- Northern Discovery Initiative: Exploring new targets in the project's northern section along the extension of the Youanmi Shear Zone, an area with no previous exploration
The initial soil sampling program across the western magnetic feature is expected to be completed within 10 days, with results to follow shortly thereafter.
Understanding the Errolls Gold Project
The Errolls Gold Project sits within the Barrambie Greenstone Belt, strategically positioned between Sandstone and Meekatharra in Western Australia's gold-rich Murchison region. The project's geology presents compelling exploration potential:
- Straddles the contact between granite in the west and Archean greenstone in the east
- Features a major shear zone (Youanmi Shear Zone) along the granite-greenstone contact
- Contains mineralised quartz veins that outcrop along this sheared contact
- Includes the Errolls Legacy Prospect with massive quartz veins exposed at surface for 300m
What Makes Errolls Legacy Prospect Significant?
The Errolls Legacy Prospect features massive quartz veins with several characteristics that suggest substantial exploration potential:
- Trend in a NNW direction with a relatively flat dip (~30°) to the west
- Veins up to 8m wide at surface (narrowing at depth)
- Flat-lying branch veins extending up to 24m east of the main trend
- Branch veins generally up to 1m thick but can reach 3 meters
- Exceptional gold grades up to 50g/t Au in some veins

Understanding Lenticular Gold Deposits
The gold-bearing veins at Errolls are described as "lenticular in habit with patchy grades," a common characteristic in many high-grade gold systems.
What are lenticular gold deposits?
Lenticular gold deposits refer to lens-shaped bodies of mineralisation that tend to pinch and swell along strike and down dip. This geological pattern creates zones of variable thickness and grade distribution.
In practical terms, these deposits form when gold-bearing fluids move through geological structures and precipitate minerals in spaces that expand and contract. The resulting ore bodies have a lens-like shape when viewed in cross-section, with the thickest parts often containing the highest concentrations of gold.
Key characteristics of lenticular gold deposits:
- Variable thickness across the deposit, with sections that widen and narrow
- Irregular distribution of mineralisation
- Often associated with structural controls such as shear zones
- May contain extremely high-grade zones within a broader mineralised envelope
- Require careful drilling programs to properly define and delineate
Why this matters to investors:
Lenticular deposits often contain concentrated zones of high-grade gold that can be economically significant despite their irregular shape. The patchy nature of mineralisation means exploration requires strategic drilling to identify the richest zones, but when these zones are discovered, they can deliver exceptional gold content as evidenced by the high-grade intercepts at Errolls.
For investors, understanding this deposit style explains both the spectacular grades encountered (up to 51.85g/t Au) and the importance of the upcoming drilling program in defining the extent and continuity of these high-grade zones.
Investment Potential: Why Errolls Matters
The Errolls Gold Project represents a compelling investment opportunity for several reasons:
-
Proven High-Grade Gold Presence: Historical drilling has confirmed exceptional near-surface gold grades, including multiple intercepts above 10g/t Au
-
Strategic Location: Situated in the established Murchison goldfields between major gold mining centres
-
Unexplored Territory: The northern extension of the mineralised trend has seen no previous exploration, offering discovery potential
-
Infrastructure Advantages: Located in Western Australia's well-established mining region with excellent access to processing facilities
What's Next for Breakthrough Minerals
Investors should keep an eye on several upcoming catalysts:
- Soil sampling results expected in July 2025
- RC drilling program scheduled to commence in early August 2025
- Aircore drilling to explore the northern extension of the mineralised trend
- Assay results from both drilling programs expected in Q3 2025
Why Investors Should Watch Breakthrough Minerals
Breakthrough Minerals presents an attractive opportunity for gold-focused investors for several compelling reasons:
-
Early-Stage Value Creation: The company is at the beginning of its exploration journey at Errolls, offering ground-floor opportunity before potential discoveries are priced into the stock
-
Exceptional Grade Potential: The historical intercepts of up to 51.85g/t Au demonstrate the high-grade nature of the system, which could translate to economical extraction even with modest tonnage
-
Dual Strategy: By simultaneously exploring known mineralisation extensions and untested areas, Breakthrough has structured its program to balance near-term results with future potential
-
Active News Flow: With field work already underway and drilling to commence soon, investors can expect regular updates and results over the coming months
Breakthrough Minerals gold exploration has positioned itself in a prospective gold region with confirmed high-grade mineralisation and substantial exploration upside. The company's approach to exploration, demonstrated by the immediate commencement of field work following acquisition, suggests a commitment to rapidly advancing the project and creating shareholder value.
