Question · Q1 2026

John Charles Tumazos asked about the impact of the August 11 U.S. Steel Coke accident on Worthington Steel's supply chain, specifically if Worthington, as a preferred customer, experienced any disruption. He also sought an interpretation of the accident's broader market implications, questioning whether it would remove 3 to 4 million tons of crude capacity or if U.S. Steel would procure third-party coke, prime scrap, or slabs.

Geoff Gilmore, CEO, President & Director, confirmed that the U.S. Steel Coke accident would not impact Worthington Steel's business, citing strong relationships with multiple mill sources and no anticipated supply chain interruptions. Regarding the broader market impact, Mr. Gilmore stated he did not have an answer, ruling out buying slabs due to tariffs but unsure about other procurement options for U.S. Steel.

John Charles Tumazos's questions to Americas Gold & Silver (USAS) leadership

Question · Q4 2019

John Charles Tumazos inquired about the long-term potential at Relief Canyon, specifically asking for a review of any data on sulfides beneath the oxides and what, if any, additional work the company has done to explore this later-phase potential, including data inherited from Pegasus.

Answer

President, CEO & Director Darren John Blasutti stated that the company has done almost zero new exploration work on deep sulfides, as the focus has been on constructing and commissioning the oxide mine. He mentioned plans to spend about $1.9 million in the current year on drilling to replace mined reserves and to bring in geological consultants to develop a foundational understanding of the system. COO Daren Dell added that unfortunately, all historical data from the previous operator, Pegasus, was lost.
