S2’s first Jillewarra drilling: exploration pipeline signals for WA mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Exploration activity is ramping up across Western Australia as S2 Resources prepares its first drilling program at the Jillewarra gold project in the Murchison, while Lefroy Exploration advances metallurgical testwork and resource growth at its Goldfields assets. Rincon Resources is simultaneously expanding copper–gold drilling in the Pilbara, targeting extensions to existing mineralised zones rather than pure greenfields step-out. For geotechs and mine planners, the cluster of early-stage drilling, metallurgy and resource definition signals a strengthening pipeline of potential open-pit and underground projects in key WA belts.
Technical Brief
- S2 Resources is preparing a maiden drill program at the Jillewarra gold project in WA’s Murchison.
- Lefroy Exploration is advancing metallurgical testwork on its Goldfields gold assets to refine processing assumptions.
- Rincon Resources is expanding copper–gold drilling in the Pilbara, targeting extensions to known mineralisation.
- Program updates span three key WA belts: Murchison, Eastern Goldfields and Pilbara, aiding regional targeting.
Our Take
Lefroy Exploration’s work at Lucky Strike in the Western Australian Goldfields, noted in our recent coverage, suggests that S2 Resources is advancing Jillewarra into a region where juniors are actively de‑risking gold targets rather than just holding ground.
With Ramelius Resources progressing the Roe gold project under a standard EPA Part V pathway, regulatory signals in Western Australia remain relatively predictable for gold projects, which likely benefits early‑stage explorers like S2 Resources, Lefroy Exploration and Rincon Resources when planning follow‑up drilling and potential scale‑up.
