Inca One Gold Corp. said Jan. 23 that its subsidiary Chala One SAC completed the 90-day ramp-up at the Chala One mill site in Peru at the end of December 2016 and achieved the highest level of processing since the start of commercial operations in February 2015.
The company processed 2,885 tonnes of gold-bearing material during the month, compared to an average of 875 tonnes per month from January through September, reflecting a 230% jump.
The daily average throughput in December climbed up to 93 tonnes per day, a significant increase over the previous nine-month average of 29 tpd.
Despite some quickly resolved maintenance issues, which forced a temporary slowdown in production activities in early December, Chala One successfully processed 16 days in excess of 100 tpd, with daily throughput reaching an all-time high of 130 tpd, achieved Dec. 31.
Chala One, meanwhile, produced 1,330 ounces of gold in December as compared to the nine-month average of 417 ounces per month, an increase of 219%.
Mineral supply also peaked with daily deliveries to Chala One through December, climbing to the year's highest level as the company sourced and paid for 2,805 tonnes of gold-bearing material, a 162% increase over the nine-month period average of 1,071 tonnes per month.
