Leagold increases Los Filos open pit reserves by 122%

VANCOUVER, Nov. 14, 2018 /CNW/ - Leagold Mining Corporation (TSX:LMC; OTCQX:LMCNF) ("Leagold" or the "Company") is pleased to announce an increase of the Proven and Probable mineral reserves (P&P reserves) at the Los Filos open pit to 40.5 million tonnes grading 0.60 g/t containing 780 thousand ounces (koz) of gold as of October 31, 2018 (see Table 1). This represents a 122% increase over the December 31, 2017 estimate of 351 koz. After accounting for mining depletion of 99 koz from January 1 to October 31, 2018, the total addition to the Los Filos open pit P&P reserves is 528 koz. This reserve update does not reflect changes to the Bermejal open pit or Los Filos underground mining areas, or potential additions from the Bermejal underground deposit.

Leagold CEO Neil Woodyer commented: "As we are nearing the completion of our site-wide studies on options for Los Filos mine expansion, the integration and scheduling of the mining and processing of the four sources of ore is a complex task to optimize. We now have the good problem of re-scheduling to include this significant increase in gold reserves at the Los Filos open pit which will contribute to the production schedule until 2027. This is just one component of the expanded Los Filos mine, and it provides an indication of the expansion potential. We are also completing studies to update the mineral reserves for Los Filos underground and Bermejal open pit, establish an initial mineral reserve for Bermejal underground, and evaluate the increased benefits of constructing a carbon-in-leach plant to improve recovery rates."

Table 1. Los Filos Mine Open Pit Mineral Reserve Statement (Effective as of October 31, 2018) (Excludes Bermejal Underground, Bermejal Open Pit, Los Filos Underground)

Classification	Tonnes (kt)	Au Grade (g/t)	Au Contained Ounces (koz)
Proven	32,300	0.62	647
Probable	8,200	0.51	133
Total Proven and Probable	40,500	0.60	780

Notes:
1.	Mineral Reserves are based on Measured and Indicated Mineral Resources within pit designs and supported by a mine plan, featuring variable throughput rates (depending on the pit being mined), variable metallurgical recoveries (depending on geometallurgical domain), and cut-off optimization.
2.	Metal price assumption for gold was US$1,200/oz.
3.	Open Pit Mineral Reserves:
	a.	Los Filos Open Pit includes the mineralization within the planned 4P pit extension.
	b.	Los Filos Open Pit crush-leach ore is based on an operational 0.36 g/t Au cut-off grade; ROM ore is based on a variable 0.146 to 0.314 g/t Au operational cut-off grade that is determined by lithology. Los Filos Mineral Reserve is based on a 0.192 g/t Au cut-off grade.
	c.	Process gold recoveries vary from 54% to 76% for crush-leach ore and from 30% to 64% for ROM ore at Los Filos Open Pit; Technical Report for Los Filos Gold Mine, Guerrero State, Mexico Page xviii Los Filos Mine Effective Date: December 31, 2017
4.	Tonnage and grade measurements are in metric units. Contained gold is reported as troy ounces.
5.	Summation errors may be present due to rounding.

The additional contribution from the Bermejal underground expansion project cannot yet be reported as a mineral reserve until feasibility level studies are completed and an integrated site-wide mine plan is finalized. A site-wide independent technical report which will now be required is under way and will be available by year-end. The report will incorporate this Los Filos open pit mineral reserve update within a new site-wide production plan, including contributions from the Bermejal underground, Bermejal open pit, and Los Filos underground mine.
