AI desk brief

Critical One Energy signed a binding MOU with SICC for its Howells Lake antimony-gold project in Ontario, securing C$25 million of strategic capital, a construction financing facility of up to C$400 million, and an exclusive offtake agreement for up to 150 million pounds of future antimony production at international benchmark prices. SICC also agreed to invest C$15 million at C$1.20/share, a 48% premium to Wednesday’s close, for a 12% fully diluted stake, while the structure gives Critical One carried equity in the planned Ontario processing facility.

The deal reinforces development momentum for Canada’s largest undeveloped antimony deposit and links mine feedstock to an Ontario processing hub. Critical One said the partnership positions it as both a future supplier and equity partner; the stock rose 3.7% in Toronto on Thursday.
