BOA strengthens Ricci Lee copper system with new high-grade results

Ricci Lee results extend a high-grade copper pattern

BOA Resources Limited (ASX:BOA) has added another layer of substance to its Ricci Lee copper story, reporting high-grade copper in 20 of the 23 reverse-circulation holes assayed so far. The latest results show continuity over more than 400 metres of strike and down dip, including broad mineralisation close to surface.

The strongest new intersection was 10 metres at 3.60% copper from 31 metres in hole 26NCRC032, including 6 metres at 5.57% copper. Other notable results included 22 metres at 1.74% copper from 104 metres, including 10 metres at 2.81%, in 26NCRC013, and 11 metres at 1.83% copper from 66 metres, including 5 metres at 3.53%, in 26NCRC012.

The update builds on the initial Ricci Lee drilling results, which returned significant copper in all six of BOA's first reported RC holes. The company says the new assays strengthen the interpretation of the Main Lode rather than describing the mineralisation as a collection of isolated, narrow zones.

Second lode emerges in northern Ricci Lee

Two holes in the northern portion of the prospect have also helped define what BOA calls an emerging parallel Hanging-Wall Lode. Hole 26NCRC012 returned 11 metres at 1.83% copper from 66 metres, while 26NCRC013 delivered 24 metres at 1.05% copper from 17 metres, including 4 metres at 3.40%.

That same 26NCRC013 hole intersected the Main Lode at depth, with the 22-metre interval at 1.74% copper. BOA also pointed to shallow results from 26NCRC029, which returned 11 metres at 3.20% copper from just one metre, including 6 metres at 5.53%, and 26NCRC031, which returned 35 metres at 1.15% copper from surface.

These are exploration results, not a resource estimate. The reported widths are down-hole intervals and true widths are not yet known. BOA says the plunge of the Main Lode will become clearer as further results arrive, information that is expected to guide deeper drilling.

Pending assays will test the emerging interpretation

Assays are still outstanding for 23 of the 46 RC holes drilled at Ricci Lee, while aircore results from five other Neds Creek prospects are also pending. Across the completed Neds Creek campaign, BOA drilled 138 holes for 13,086 metres, giving the company a substantial flow of exploration results through the fourth quarter of 2026.

One hole, 26NCRC038, was abandoned because of poor ground conditions and is expected to be completed in a future program. BOA currently owns 49% of Neds Creek and operates the project; shareholders are due to consider its proposed acquisition of the remaining 51% on 12 October. Until that process and the exploration work advance, Ricci Lee remains a promising but early-stage copper target rather than a defined mineral resource.
