Stock Market Today: Trilogy Metals Surges as Rally Continues After U.S. Defense Investment
Trilogy Metals Inc (NYSEMKT: TMQ) jumped 61.59% to close at $10.60 as its post-announcement rally continued. Trading volume reached 147.7 million shares, more than 22 times its three-month average of 6.54 million. Shares hit a new 52-week high of $11.29 intraday.
The S&P 500 (SNPINDEX: ^GSPC) slipped 0.16% to 6,644.31, while the Nasdaq Composite (NASDAQINDEX: ^IXIC) fell 0.76% as markets remained pressured by renewed U.S.–China trade tensions.
Among mining peers, Perpetua Resources Corp (NASDAQ: PPTA) declined 0.73% to $27.19, and NovaGold Resources Inc (NYSEMKT: NG) slipped 1.30% to $9.88.
The surge follows the October 6 announcement that the U.S. Department of Defense will invest $35.6 million for an estimated 10% ownership stake in Trilogy. The move supports the company's work in Alaska's Ambler mining district, which holds some of the world's richest known copper-dominant polymetallic deposits. The investment has lifted Trilogy's shares 401.9% since the news and highlights growing government interest in securing domestic sources of copper, cobalt, zinc, and lead--materials essential for energy infrastructure, defense technology, and advanced manufacturing. Investors will be watching for progress on permitting, project development, and further government partnerships in the months ahead.
