While specific details on ore sorting performance at Barrick’s Hemlo Mine are not readily available, the site has undergone significant modernization, including a critical transition from open pit to underground mining to extend its life as a Tier Two asset. This transformation focuses heavily on increasing underground throughput and optimizing mill feed sources (Barrick, 2020).
Barrick’s broader commitment to technology-driven efficiency is clear through processing innovations implemented at other sites such as bioleaching at Goldstrike and advanced grinding technologies. These advancements strongly suggest the potential for similar high-precision approaches at Hemlo to improve recovery.
For concrete information on ore sorting at Hemlo, reviewing Barrick’s post-2020 technical reports or operational updates detailing the underground ramp-up and strategies for more efficient ore feed management would be necessary.
Barrick’s commitment to modernization suggests they achieved significant gains during this transition. Based on industry knowledge, what were the biggest expected gains at Hemlo in terms of grade increase or cost reduction, and what operational shift made that possible? Share your insights!
