As cobalt prices soar, Castle Silver Resources hopes to revive a past-producer in Ontario’s historic Cobalt camp.

Two companies plan to co-operate on a proposed facility to process Quebec gold and Ontario cobalt-silver. Castle Silver Resources TSXV:CSR and Granada Gold Mine TSXV:GGM announced a provisional milling agreement to develop a flowsheet for a plant that would be located on Castle Silver’s property in Gowganda, Ontario. The Granada gold mine is located near Rouyn‐Noranda and about 204 kilometres by road from Gowganda.

The companies have overlapping management and directors. Funding would come from US$20 million in loans, “which debt raise will be facilitated by a family office in the UK,” the companies stated.

The agreement foresees batch processing of at least 600,000 tonnes of Granada material grading four grams per tonne over three years. An option would allow treatment of another 1.4 million tonnes of pre‐concentrated waste rock. Initial metallurgical tests used a conventional coarse gravity process to achieve 70% gold recovery from Granada waste rock averaging 0.5 g/t, producing a 4.5 g/t gravity concentrate to be further processed at the mill.

The Granada project reached the pre-feasibility level in 2014 and a resource update last June. The Castle mine underwent intermittent silver-cobalt production between 1917 and 1989. Assays are pending from last summer’s 22-hole, 2,405-metre drill campaign.

In June Castle Silver closed the final tranche of a private placement totalling $1.2 million.
