- Boab Metals has completed more than 3,000m of the planned 4,200m drilling at Sorby Hills.
- The Phase V drilling program is focused on improving mine life and proposed production capacity at the project, as part of the ongoing DFS.
- Core sampling indicates potentially game-changing extensions to Norton and Omega deposits
- A number of drill holes have extended mineralisation at B-Deposit.
Boab Metals Limited (ASX: BML) is in high spirits with the ongoing Phase V drilling at its 75%-owned Sorby Hills Joint Venture, delivering encouraging initial results. It aligns well with the solid track record from previous drilling programs. The Company announced the completion of nearly three-quarters of the planned 4,200m program at Sorby Hills, stationed in the mining jurisdiction of Western Australia.
The drilling is complete on 31 holes, including four holes that were later added due to the interpreted success based on core logging of planned holes.
The Phase V drilling program was designed to explore opportunities to improve mine life and the proposed production capacity of Sorby Hills as part of the ongoing Definitive Feasibility Study (DFS).
Remarkable Success from the drilling
The Phase V drilling is strategically focused on testing and validating the interpretation of portions of the project’s resource situated close to, but outside the current open-pit designs. It would allow the incorporation of the prospective tonnes into the DFS mine plan.
So far, drilling over more than 3,000m is complete, and the Company has submitted approximately 1,100 core samples to a Darwin-based laboratory for assaying.
Success so far has included:
- A newly recognised hydrothermal mineralisation style has been extended for over 100m beyond the current boundary at northwest Omega.
- The geological model of the Alpha deposit and the fault-hosted zinc mineralisation has been confirmed.
- Mineralisation is extended adjacent to the B-deposit.
- The drilling intersected a new structurally controlled shallow Pb-Zn mineralisation, 500m west of the Norton deposit.
- Diamond drill core logging has confirmed the presence of secondary Pb-Zn mineralisation at the wildcat target.
Encouraging results put Omega northwest in spotlight
Highly encouraging results from the Phase IV drilling program last year propelled the company’s decision to target the northwest Omega area. To date, Boab has delineated an envelope of steeply dipping lenses of mineralisation over approximately 100m strike length.
The Company intends to undertake further step-out drilling to follow up the mineralisation open along strike to the north-northwest.

Robust silver results at Alpha and Beta Deposits
Some of the highest-grade silver results are returned from the Alpha and Beta deposits across Sorby Hills. Boab will drill the Alpha and Beta deposits for the fisrt time since the company acquired the project in 2018. In the Phase V drilling program, four drill holes have been completed at the Alpha deposit.
Drilling at Alpha, Beta and Omega northwest represents a substantial and relatively low-risk opportunity for materially extending the mine life of Sorby Hills.
Road Ahead for Sorby Hills Exploration
Boab has received significant encouragement from the core logging outcomes to extend the Phase V drilling program.
The remaining drilling program consists of:
- Cluster of holes at the central Omega deposit
- Several holes at the Beta deposit
- Drilling of conceptual targets at Eight Mile Creek.
Meanwhile, the Company is continuously investigating and interpreting the geological information generated from drilling, with a view to identify additional high impact targets for the current drilling program as well as follow-up drill hole positions for future campaigns.
