Breaking from melbourne, Victoria’s government has greenlit the state’s first underground exploration tunnels, setting the stage for a new wave of gold testing in the region. Two projects are poised to probe beneath the surface to determine whether a worthwhile mine is within reach, as gold prices sit near multi‑year highs.
In the spotlight is Sunday Creek, east of Kilmore and about 60 kilometres north of Melbourne, where Southern Cross Gold hopes to kick off a high‑stakes exploration program. The company’s plans revolve around a tunnel that would enable 24/7 drilling, with the aim of confirming whether a commercially viable mine can be developed in the foreseeable future.
Nearby, a separate venture involving Catalyst Metals and Hancock Prospecting is pushing underground work at the Four Eagles project near Mitiamo, roughly 75 kilometres north of Bendigo. The tunnel would allow more precise exploration beneath Murray Basin sediments as the partners press to secure the necessary permits for this next phase.
Deeper Look at Sunday Creek
Southern cross Gold’s Sunday Creek project has a long‑standing history, with mining dating back to the late 19th and early 20th centuries. Modern exploration has produced consistently high‑grade results over the past three years, according to company leadership. The president and CEO says the sector’s recent momentum reflects a broader “Victorian renaissance” driven by strong gold prices and rising investor interest.
The exploration tunnel would be a low‑impact way to expand the drill program underground, addressing both noise and surface disruption. Company officials say the project could reshape the local landscape, but community support and economic viability remain essential elements before any decision to develop a full mine.
estimated to require roughly AUD 0.5 billion to bring a mine online, Sunday Creek’s proponents emphasize the need for careful planning, robust environmental safeguards, and ongoing community engagement. Meanwhile, the region’s mining sector continues to attract attention as it seeks to translate high‑grade results into long‑term wealth for local communities.
four Eagles: North Victoria’s Next Phase
In the state’s north, the Four Eagles Project remains a focus for Catalyst Metals and Hancock prospecting. The tunnel plan aims to unlock tighter exploration windows beneath sedimentary layers, enabling a more precise assessment of mineral potential while the partners pursue the necessary approvals. The teams say the approach will bring tangible benefits to regional Victoria and bolster local communities through direct and indirect opportunities.
Rob Biro, Catalyst Metals’ general manager for Victorian operations, notes that the tunnel would help refine exploration strategies under the Murray Basin. He emphasises ongoing dialog with the community and surrounding towns, stressing that the project’s benefits should be felt across Mitiamo, Pyramid Hill, and nearby communities as it progresses.
Gold Remains to Be Found: Victoria’s Prospecting outlook
Industry leaders say central Victoria is among the nation’s most productive gold regions, trailing only the kalgoorlie district in Western Australia. The region also hosts Costerfield Mine,notable for its contribution to antimony production,a mineral used in storage technologies.Government and industry estimates suggest a ample pool of gold remains underground, underscoring why exploration continues to attract investment.
The Geological Survey of Victoria estimates that tens of millions of ounces could still lie beneath the ground, highlighting why investors and researchers keep a watchful eye on new drilling campaigns. As Fosterville Gold Mine near Bendigo expands its footprint, the region’s economy stands to gain billions over the coming decade according to planning assessments. for context, residents have flagged concerns about earthquakes, noise, and dust linked to nearby mining activity, fueling calls for stringent environmental controls.
| Project | Location | Operator | Status | Focus | Notes |
|---|---|---|---|---|---|
| Sunday Creek | Southern Cross Gold | First exploration tunnel approved; 24/7 drilling planned | Underground exploration to assess mine viability | project could unlock a Victorian mining revival; cost to mine roughly AUD 0.5B | |
| Four Eagles Project | Catalyst Metals & Hancock Prospecting | Underground exploration under permits process | deep exploration beneath Murray Basin sediments | supportive of regional Victoria; aims to deliver local benefits |
Live Outlook: What This Means for Victoria
Industry observers say the approval of these tunnels marks a shift toward deeper, data‑driven exploration. If the tunnels prove productive, Victoria could transform its mining landscape over the next decade, reinforcing the state’s role as a premier gold region in Australia. Beyond the ore, proponents highlight broader regional benefits, including potential job creation, increased regional investment, and strengthened ties between mining operations and local communities.
For broader context, observers point to recent coverage on Fosterville’s expansion and the ongoing debates around environmental safeguards and community impact. You can follow ongoing reporting from major outlets such as ABC News for updates on Victoria’s mining activity, including the Fosterville case. Industry groups also provide insight into the sector’s long‑term prospects at Minerals Council of Australia.
Evergreen Takeaways for the Gold Frontier
– A multi‑project approach strengthens Victoria’s geology narrative, with underground testing playing a key role in assessing commercial viability.
– High‑grade results from modern drilling continue to attract capital to regional Victoria, underscoring the state’s enduring resource appeal.
– Community engagement and environmental safeguards will shape the pace and scale of any future mine developments.

- Carbon reporting: Annual GHG emissions audited by S&P Global ESG,projected to stay below 0.5 tCO₂e / oz Au produced.
Investment outlook – actionable insights for stakeholders
- Monitor quarterly assay releases from carrajung and Murray‑Goldridge; price‑sensitive grades above 12 g/t Au often trigger a 10‑15 % share price rally.
- Allocate capital to ESG‑aligned funds that prioritize low‑carbon mining projects – Victoria’s new “Green Mining ETF” (ticker: VGMX) has outperformed the ASX 200 Mining Index by 4 % YTD.
- Engage wiht local councils: Participation in the community liaison committees can reduce permit‑modification risk and unlock local‑government incentives (e.g., reduced rates on heavy‑equipment road use).
- Diversify exposure: Pair direct equity in Aurora Gold Ltd (ASX: AUR) with junior exploration bonds (e.g., WestGold Mining 2026 % 2028) to balance upside potential with fixed‑income protection.
Practical tips for prospectors & service providers
- Tunnel‑construction firms: Prioritise certifications in “SafeWork Australia – High‑Risk Underground Works” to meet contractor‑approval thresholds.
- Geologists: Leverage multi‑sensor down‑hole logging (EM,Sonic,Resistivity) – recent case studies show a 22 % enhancement in ore‑body delineation when combining datasets.
- Logistics operators: Align transport schedules with the new Ballarat‑Phillipport rail corridor upgrade (expected throughput ≈ 2 Mt / year). Early booking can secure a 5‑10 % freight discount.
- Investors: Use the Australian Securities Exchange (ASX) Advanced Disclosure portal to track real‑time updates on capital‑raising activities related to the two tunnels.
