Caspin Resources Limited has identified new regional discovery opportunities at the Moss and Ardlethan prospects within the Bygoo Tin Project in New South Wales, supported by infill soil sampling and reconnaissance reverse circulation drilling.

At the Moss Prospect, infill soil sampling has defined a strong tin geochemical anomaly located 500 metres along strike from the Kelpie Deposit. Initial reverse circulation drilling completed at the northern part of the prospect during June did not intersect the targeted granite-rhyolite contact, but encouraged mineralogy and alteration within the rhyolite indicate proximity to a hydrothermal system in the underlying granite. Caspin has revised the interpreted position of the granite contact using gravity data and commenced follow-up reverse circulation drill testing using a minimum of two holes to test the core of the new anomaly.

Parallel reconnaissance-style reverse circulation drilling across seven holes at Ardlethan East and Ardlethan South returned broad anomalous results in tin and pathfinder elements. Hole BRC042 intersected a peak result of 4 metres at 0.49% tin from 8 metres depth within sedimentary rocks, aligning with target hypotheses for sedimentary rock-hosted breccia pipes concealed beneath shallow alluvial cover. At Ardlethan South, an expanded soil survey identified a strongly tin-anomalous section along the granite contact extending over 1,000 metres of strike. Hole BRC045, located approximately 400 metres east of the contact zone, returned broad intervals including 3 metres at 0.56% copper and 20.3 grams per tonne silver from 80 metres, alongside 1 metre at 0.12% tin from 83 metres.

“Recent high-grade results from the Kelpie Deposit have demonstrated a clear pathway to resource growth with an updated resource estimate already scheduled for September. In parallel with the ongoing resource extension work at Kelpie, the Company has now developed several highly prospective targets across the Bygoo Project with potential for new discoveries.

We're excited by these new targets. The Moss Prospect is the most direct analogue to Kelpie and this new soil anomaly is of a similar magnitude and only 500m along strike.”

Caspin acquired a 100% interest in the Bygoo Tin Project in December 2024 following the exercise of an option agreement.

Drilling at the Moss Prospect is currently underway, with operations scheduled to shift to the Ardlethan South and East prospects later in the year. Caspin has scheduled an updated resource estimate for the Kelpie Deposit in September 2026.
