Hummingbird Initiates Extensive Drill Campaign at Yanfolila in Mali.

Hummingbird Resources has initiated an extensive exploration drill campaign on its Yanfolila mining permit in Mali, targeting conversion of resources to reserves and extension of mine life at the Yanfolila mine. Four rigs were on-site as of early July and will be drilling more than 50,000 meters (m) across six known deposits, all in close proximity to the Yanfolila processing plant.

Hummingbird's exploration drill strategy is focused on infilling currently defined resources at the six deposits in the 2.2-million-ounce (oz) resource base. By targeting these resources, Hummingbird anticipates that the current mine life will ultimately be extended beyond 10 years, and, at certain stages in the life-of-mine plan, grade delivered to the process plant will be improved. This could result in higher annual production levels and improve projected annual free cash flow.

The Gonka Gonka deposit 5 kilometers (km) from the Yanfolila process plant is budgeted for 20,000 m of drilling, testing an opportunity to substantially increase Yanfolila mine life and improve the mill feed grade through the later years of the current mine plan. Using a phased approach, in-pit resources will be drilled out first before commencing deeper drilling targeting underground resources. Further and substantial reserve and resource growth is considered to exist at Gonka down dip of the current known resources.

Other drilling will include 10,000 m at the Guirin West deposit less than 2 km from the process plant to quickly define further oxide resources that will supplement the fresh ore currently being mined from Komana East; 5,000 m at the Komana West deposit 3 km west of the process plant; 10,000 m at Sanioumale West along strike of Guirin West; and 10,000 m at Sanioumale East along strike and north of Komana East and Gonka.
