Rapid Critical Metals (ASX:RCM) has reported additional high-grade silver assay results from the final six diamond drill holes at its wholly-owned Webbs Silver Project in northern New South Wales, according to a Friday Australian bourse filing.

The results include 0.59 meters at 4,216 grams per tonne silver equivalent within a broader 2.5 meters at 1,075 grams per tonne silver equivalent from 39.5 meters, confirming high-grade silver across multiple drill sections, per the filing.

The results support the presence of additional sub-parallel mineralized structures, complement previous drilling, and indicate that mineralization remains open along strike and at depth, the filing said.

The company is advancing its NSW silver exploration program, including follow-up drilling at Webbs, resource growth across the Webbs-Webbs Consol corridor, updating geological and resource models, and maintaining strong funding for planned activities, the filing added.

The company's shares tumbled 22% in recent Friday trade.
