Updated Reserves/pages And Recent Fazenda Drill Results In Brazil

 

VANCOUVER - Leagold Mining Corporation reported updated mineral reserve and mineral resource estimates at its RDM and Fazenda mines in Brazil and the filing of the associated updated technical reports.  The Company also reports highlights from the 2018 drill program at Fazenda. At the RDM mine, Proven and Probable mineral reserves total 24.7 million tonnes (Mt) grading 1.0 grams per tonne (g/t) and containing 789 thousand ounces (koz) of gold and Measured and Indicated mineral resources total 39.3 Mt grading 1.0 g/t and containing 1,259 koz of gold.  The results at RDM represent a net reduction of 41 koz since the 2017 reserve estimate which is attributable to depletion.  Measured and Indicated resources increased by 57 koz over the December 31, 2017 mineral resource estimate.

RDM is a conventional open pit and carbon-in-leach (CIL) operation, which is scheduled to process 7,000 tonnes per day (tpd) and recover over 700,000 oz of gold over a mining life of eight years plus two additional years of stockpile processing, for a total mine life of 10 years.  Significant exploration potential has been identified laterally along strike, both north and south of the existing pit, as well as down-dip.

At the Fazenda mine, Proven and Probable mineral reserves total 5.4 Mt grading 1.84 g/t Au and containing 319 koz of gold, representing a net decrease of 58 koz since the 2017 reserve estimate. The reduction in reserves is attributable to depletion.  Measured and Indicated Resources total 7.5 Mt grading 2.3 g/t and containing 558 koz of gold.

At current mining rates, the Fazenda reserves represent a mine life of approximately four years. Fazenda has operated for over 30 years and has a solid track record of successfully replacing production each year with new reserves through drilling and development.  The plant is operated as carbon-in-leach (CIL) with a capacity of 1.3 million tonnes per year.  The majority of ore is sourced from underground mining with supplemental feed from open pits.

Exploration potential is laterally along strike and at depth below the existing Fazenda operations. The area has seen extensive exploration along the mineral trend and the exploration team has successfully identified additional underground targets in parallel structures to the principal zones that were already being mined.  This exploration success is anticipated to continue and will include some deeper targets on known mineralized structures.

The Fazenda mine employs industry standard drilling and sampling procedures. The drill holes were oriented perpendicular to the mineralized structures with the majority of the holes oriented to the north.  The holes were drilled with a range of inclinations to provide sufficient spacing to support mineral resource estimation.  Diamond drill holes are used to provide BQ sized core samples.  The core is logged and the entire core is sent for assay.
