Hundreds of small mineral exploration companies may have their stock delisted by Canada's TSX Venture Exchange in the coming month. As commodity prices boomed in the past decade, a flood of new issuers swelled the ranks of the Venture, but the money has dried up over the past 2 years. Hardest hit are the Venture-listed, exploration-stage companies that depend on equity financing to develop their properties to the point where they can build a mine or sell the asset to a major. While the mining sector has always been subject to boom and bust, the potential shakeout could be especially damaging this time.
