TMS Shares Rise 71 Percent Before Re-assay Results Confirm Initial Assays

Trading Surge Preceded Re-assay Results

Tennant Minerals Limited (ASX:TMS) saw its share price jump from 0.7 cents to an intraday high of 1.2 cents on May 7, 2026, accompanied by a notable increase in trading volume. The company has confirmed that as of that date, it held no undisclosed information that could explain this market activity. The spike preceded the receipt of re-assay results from diamond drillhole BBDD0050 at its Bluebird copper-gold-bismuth discovery, which were only received on the afternoon of May 8.

Re-assay Results Confirm Initial Assays

Following visible gold and native copper observed in the original samples, Tennant Minerals requested re-assaying of 27 samples initially sent to Intertek Laboratories on March 18, 2026. The re-assays, intended as a more representative check, were expected not to materially differ from the initial results disclosed on May 1. Indeed, the company confirmed that the 26 re-assayed samples returned results consistent with the original assays, with the final sample’s result pending but anticipated to align similarly.

Market Interest Tied to Regional Peer Activity

The company noted that heightened investor interest in the Tennant Creek mineral region, particularly movements in the securities of its peers and partners such as ASX:CUF, may have contributed to the trading surge. This regional momentum aligns with Tennant Minerals’ recent announcements of high-grade intersections at Bluebird, including an 18m interval grading 10.1 g/t AuEq, which has attracted attention given the strategic value of contained bismuth and copper. The company’s ongoing drilling and development plans at Bluebird were bolstered by a $2.8 million capital raise earlier in May to expand the discovery footprint and advance metallurgical studies, underpinning market optimism around the project’s potential capital raise to expand Bluebird and exceptional gold-bismuth-copper grades.

Compliance with ASX Listing Rules and Disclosure

Tennant Minerals confirmed full compliance with ASX Listing Rules, particularly Listing Rule 3.1 concerning continuous disclosure. The company maintained strict confidentiality protocols for exploration data, with assay results securely handled by senior geological staff and the database manager before Board approval of any market release. The re-assay results were compiled into a draft announcement and approved for release on May 12, following receipt and internal review, ensuring transparency and adherence to regulatory obligations.
