Perpetua Resources is trading 5.9% down at $22.33, with no verified company-specific announcement explaining the decline.

  • The September 28 update described construction and exploration progress but did not link it to a share-price reaction.
  • Reuters reported oil rose and Treasury yields climbed after the U.S. rejected Iran’s proposal, reviving inflation concerns. Broader risk-off pressure and materials-sector weakness may contribute, but available evidence does not establish a direct cause for the stock’s move.
