Hecla’s gold production of more than 180 000 oz was not replaced, while proven and probable reserves declined by 6% to 2.6-million ounces, owing to cost increases which increased the cut-off grade at Casa Berardi, in Quebec.Zinc production was replaced and reserves increased by 4% to 944 000 t. Lead production of 55 000 t was replaced, with an increase of 7% to 785 000 t of reserves.
Measured and indicated silver ounces increased by 6% to 219-million ounces with increases at Greens Creek, in Alaska, and the addition of Keno Hill which offset the decrease owing to conversion of material to reserves at Lucky Friday, in Idaho. Measured and indicated gold ounces also increased by 6% to 3.7-million ounces owing mostly to increases at Casa Berardi.
“In the past 15 years, we have replaced the 213-million ounces mined and yet have almost five times the reserves we had at the start of 2008. That is over 400-million ounces of silver that we have replaced and grown.
