Expect pricing announcement within 1-2 days. Monitor for final IPO price and first-day trading performance. The 60.7% post-IPO control by Electrum Group limits governance risk but may reduce float and liquidity. Silver price trends and the Sunshine Mine technical report (S-K 1300 Initial Assessment) will be key valuation drivers post-listing.
