PRYM Prime Mining Corp

Prime Mining Corp. (“Prime”, or the “Company”) (TSX: PRYM) (OTCQX: PRMNF) (Frankfurt: O4V3) confirms that trading in its common shares was halted at the open of markets in connection with its previously announced graduation to the Toronto Stock Exchange (“TSX”). The graduation has been completed as planned, and concurrently it was expected that the Company would be delisted from the TSX Venture Exchange (“TSXV”) and trading would commence on the TSX as of the open of markets.

As a result of a delay in its coordination with the TSX, the TSXV delisting was not completed concurrently by the TSXV and cannot be completed until after the close of markets today. Following the close of markets today, the TSXV delisting will be completed, and trading is expected to begin on the TSX at the open of markets on December 6, 2023 under the existing ticker symbol “PRYM”.

At this time, the Company confirms that it is not aware of any undisclosed material concerning its affairs. For further information regarding the graduation, readers are encouraged to review the news release issued by the Company on November 29, 2023.
