Significant Rhodium Mineralisation at XC-22 Prospect
HIGHLIGHTS
- The lower PGE-rich zone in YARC0022 has been assayed for the full six element PGE suite
- Significant rhodium up to 465ppb associated with platinum and palladium identified
- Rhodium is an extremely rare and valuable PGE
- PGE-richzone now reports as; 13m @ 1.08g/t 4E (Pd+Pt+Rh+Au), 0.26% Ni & 0.21% Cu from 101m,
- including 2m @ 2.45g/t Pt, 0.40g/t Pd, 0.41g/t Rh, 0.03g/t Au, 0.23% Ni, 0.09% Cu from 112m
- Almost no assaying for rhodium in historical exploration at Yarawindah Brook
- Caspin to undertake selected re-assaying of past and upcoming drilling for full PGE suite
Caspin Resources Limited (ASX: CPN) ("Caspin" or "the Company") is pleased to provide results of further PGE assaying from drill hole YARC0022 at the XC-22 Prospect at the Company's Yarawindah Brook PGE-Ni-Cu Project in Western Australia.
Significant Rhodium Results Complement Platinum and Palladium Mineralisation
Following the significant results in YARC0022 (see ASX announcement of 9 February 2022), the Company elected to analyse the lower PGE-rich mineralised zone for the full six PGE suite of elements, which consist of iridium (Ir), osmium (Os), rhodium (Rh) and ruthenium (Ru), as well as platinum and palladium. This analysis has returned significant grades of rhodium associated with the already recognised platinum and palladium mineralisation, with a peak value of 465ppb Rh. Grades greater than 100ppb, or 0.1g/t, are considered highly significant. The revised intercepts are as follows:
13m @ 0.17g/t Pd, 0.74g/t Pt, 0.11g/t Rh, 0.26% Ni, 0.21% Cu from 101m, including 2m @ 0.40g/t Pd, 2.45g/t Pt, 0.41g/t Rh, 0.23% Ni, 0.09% Cu from 112m.
When adding the minor gold contribution, this can be expressed as 13m @ 1.08g/t 4E, 0.26% Ni & 0.21% Cu, including 2m @ 3.29g/t 4E, 0.23% Ni & 0.09% Cu.
Caspin's Chief Executive Officer, Mr Greg Miles, commented "This is an interesting new development for XC-22and indeed our entire Yarawindah Brook Project. It's a pleasant surprise given this is the first time we've ever assayed for rhodium and bodes well for the discovery of more mineralisation. Because of its value, small amounts as low as 100ppb can make a significant contribution to the economics of PGE deposits. We've now got an extensive assaying program ahead of us and if we can demonstrate that rhodium mineralisation occurs consistently with platinum and palladium at XC-22,then we could be another step closer to an economic discovery."

Implications for PGE Exploration at Yarawindah
Despite the value of rhodium, routine analysis is rarely undertaken because of the scarcity of the metal and significant additional cost to assay the full 6-PGE suite. Prior to Caspin's involvement in the project, only five samples had ever been assayed for rhodium as part of a metallurgical sighter program in 2006. Therefore, the potential for rhodium mineralisation has never been evaluated. The Company is extremely encouraged that its first-ever assaying of rhodium has returned such significant results.
The Company will now review all of its past exploration results with a view to selecting zones of PGE-rich mineralisation for 6-element PGE assay, with the aim to identify further rhodium mineralisation.
The current phase of drilling at XC-22 is progressing well. Assaying for rhodium will be conducted after confirmation of platinum and palladium mineralisation, with a focus on the pyroxenite-peridotite contact zone which appears to be the host of mineralisation intersected so far.

Some Facts About Rhodium
- Used in similar industrial applications to platinum and palladium, such as catalytic converters, but is generally more efficient.
- Chemically inert and doesn't oxidise making it an attractive alloying agent that improves resistance to corrosion.
- Extremely rare, usually produced as a by-product of nickel-copper and platinum-palladium processing using conventional sulphide flotation.
- GlobalproductionisdominatedbySouthAfricawithsmallercontributionsfromRussia,Zimbabwe andCanada.
- Over the past 3 years the price has ranged from approximately US$2,000oz to US$27,000oz and is currently circa $20,000oz.

YARC0024, YARC0025 and YARC0027 were unable to reach their target depth and will either be extended by diamond tails or re-drilled. YBR series holes not assayed for Ni or Cu.

ABOUT CASPIN
Caspin Resources Limited (ASX Code: CPN) is a new mineral exploration company based in Perth, Western Australia. Caspin has extensive skills and experience in early-stage exploration and development. The Company is actively exploring the Yarawindah Brook Project in Australia's exciting new PGE-Ni-Cu West Yilgarn province and the
Mount Squires Project in the West Musgrave region, one of Australia's last mineral exploration frontiers.
At the Company's flagship Yarawindah Brook Project, recent drilling campaigns at Yarabrook Hill have made new discoveries of PGE, nickel and copper sulphide mineralisation. Meanwhile, the Company continues to bring new targets to drill readiness by collecting geophysical and geochemical data across the project.
At the Mount Squires Project, Caspin has identified a 50km structural corridor with significant gold mineralisation and potential copper porphyry prospects. The Company will conduct further soil sampling and reconnaissance drilling along this trend. Caspin will concurrently continue to evaluate the potential for Ni-Cu mineralisation along strike from the One Tree Hill Prospect and Nebo-Babel Deposits.
