Discovery Alaska Readies Drill Rig as Boulder Creek Gold-Silver Testing Nears
Key Takeaways
- Discovery Alaska has finished site works, permitting and water sourcing at Boulder Creek, leaving a drilling contractor as the main step before rigs turn.
- No contractor, start date, hole count or metreage has been disclosed, so the timing of the drilling catalyst remains open.
- The first holes target historic Nerco, Inc. sites from 1985 to 1987 that identified anomalous gold and silver zones.
- Recent rock samples from those sites were described as spectacular high-grade gold and silver, with details in the 10 June 2026 release.
- The July and August Big Grass bushfire delay is behind the company, and drill program planning is now complete.
Boulder Creek site works completed as Discovery Alaska readies drill rig
Drilling is the moment an exploration story stops being theory and starts producing evidence. Discovery Alaska (ASX: DAF) has now completed site preparation and access works, permitting requirements and water sourcing, and is ready for drilling operations to commence at the Boulder Creek Gold-Silver Project in Idaho, USA.
The project sits ~90km southwest of Boise, near the historical mining town of Silver City. The Company is still finalising arrangements with a drilling contractor, and the announcement does not name one, nor does it disclose a start date, hole count or metreage.
For investors, that moves the project from planning towards execution, with drilling the next catalyst to watch.
The announcement highlights the following completed items:
- Site works completed for drill pads and rig access
- Regulatory permitting secured
- Water secured for drilling operations
- Drill program planning works completed
Jerko Zuvela, Director
“The Company is ready and excited to commence its initial drilling program at the Boulder Creek Gold-Silver Project…”

Targeting the Nerco, Inc. historic drill sites
The Company is targeting historical drilling sites completed by Nerco, Inc. between 1985 and 1987, which identified anomalous gold and silver zones. “Anomalous” simply means readings higher than the background level, a signal worth testing but not a confirmed deposit.
That targeting is supported by recent site visits and positive rock sample results from the historic sites. The results were detailed in the 10 June 2026 release, Boulder Creek Gold-Silver Project Update: High Grade Silver & Gold Rock Sample Results, and no assay figures are repeated in this announcement.
Director Jerko Zuvela described them as “spectacular high-grade gold and silver rock sample results” from the historic sites, adding that the Company is excited to drill test the Nerco, Inc. anomalous prospect area.
What this tells you is that the first test is a defined one. Modern holes are planned where earlier work already pointed to anomalism, though the announcement does not describe any resource or discovery, and the Company’s forward looking statements note there is no assurance it will confirm mineral deposits.
Understanding epithermal gold-silver systems
Epithermal deposits form when hot, mineral-rich fluids travel through rock close to the surface and deposit metals as they cool. The announcement says the project is prospective for two styles: epithermal high grade vein hosted gold-silver and disseminated gold-silver.
The two styles behave differently, which shapes how investors read drill results.
| Style | Typical feature | Why investors watch |
|---|---|---|
| High grade vein hosted gold-silver | Metals concentrated in narrow veins | Can carry high grades |
| Disseminated gold-silver | Metals spread through the host rock | Can offer broader zones |
This is general context only. The announcement makes no claims about the size of mineralisation at Boulder Creek.

Delay from the Big Grass bushfire and what comes next
The Company recently completed drill program planning, following a delay due to the “Big Grass” bushfire that occurred in the area during July and August. That planning is now done, so the delay sits in the past.
The next steps are to finalise the drilling contractor and then commence drilling. No timeline is disclosed.
Discovery Alaska holds a 100% interest in Boulder Creek (20 BLM claims), an option to acquire a 100% interest in Idaho State Lease E600117, and a 100% interest in the Chulitna Project in Alaska, USA.
For shareholders, the milestone to watch is the start of drilling at Boulder Creek.
