Vancouver, September 25, 2017 – Leagold Mining Corporation (TSX:LMC; OTCQX:LMCNF) (“Leagold” or the “Company”) has completed the surface preparation and has now commenced portal development for the 1,325 metre long exploration ramp that will provide access to the high-grade mineralization of the Bermejal Underground deposit.

Neil Woodyer, CEO stated “We have been steadily advancing the development of the Bermejal Underground as an expansion project at our Los Filos mine, and the start of the portal and ramp is a significant achievement within our initial six months of ownership. The contribution from underground mining at Bermejal will add approximately 150,000 ounces per year to the operation and bring the combined production rate to 350,000 ounces per year once fully operational.”

The portal is located in carbonate rocks on the north side of the mined-out portion of the Bermejal open pit (Figure 1). The US$13M capital budget includes a total of 3,136 metres (m) of ramp and cross-cut development and two ventilation raises totalling 560 vertical m that will be developed using a raise bore (Figure 2). A spur at the 650 m point of the main ramp will provide access to a test mining area on the southeastern part of the Bermejal Underground deposit and the mineralized body will be intersected in mid H1 2018. The exploration ramp will allow initial mining to begin in the test stope for the collection of a large-scale sample for metallurgical testing and leaching on the existing heap leach pads. The main ramp continues to the central portion of Bermejal Underground and will intersect mineralization in that area in late 2018. The design of the portal and ramp is fully dimensioned for eventual use as a production ramp and includes cut-outs for underground drilling. This development program provides the opportunity for drilling and mining over a strike length in excess of 1,200 m and along a vertical extent of more than 300 m of the Bermejal Underground deposit.

The ramp will provide access to the eastern and central portions of the deposit and will enable additional exploration, demonstrate the minability of Bermejal Underground, and advance the project towards declaration of reserves.

Leagold has selected Cominvi, S.A. de C.V. as the portal and ramp development contractor. Cominvi currently provides contract mining and development services in the Los Filos Underground mine, which has the same host rocks and type of mineralization. The contractor was mobilized in September, surface preparation of the portal area was completed (Figure 3) and the first blast for the portal is scheduled for September 25th.

Oxide mineralization along the Bermejal intrusive has an average grade of 6.7 grams per tonne (“gpt”) in the currently reported Measured and Indicated mineral resources. The recent drilling in the eastern and central portions of Bermejal Underground has provided consistent intercepts at similar grades as well as intervals of higher grade mineralization including the following results (see Table 1):

NOTES:

1. Intervals mentioned in the April 12, 2017 news release
2. Intervals mentioned in the July 13, 2017 news release
3. Intervals mentioned in the August 31, 2017 news release
4. UI = Intrusive Contact above Junction with Sill; UC = Upper Contact of Sill; LC = Lower Contact of Sill; LI = Intrusive Contact below Junction with Sill
5. Only intercepts with over 3 grams per tonne and diluted to a minimum true width of 3 metres are shown
6. Individual assays within the intercepts were capped using 40 g/t limit

Bermejal Underground Expansion Project Activities Update

An environmental permit for the mine portal and exploration ramp was completed in July 2017 (see news release dated July 31, 2017).

The Bermejal Underground drilling program is now over 50% complete with 28,846 m drilled of the planned 56,000 m. A total of 67 of the planned 113 holes have been drilled. The entire drilling program is expected to be completed within 2017 and these drill hole results will be incorporated in an updated resource estimate at the end of 2017. All holes intersected iron-oxide skarn mineralization as targeted and only two holes (BU-36-17, BU-40-17) were below a 3 gpt over 3 m diluted minimum width threshold.

The drilling shows consistent oxide mineralization at carbonate/intrusive contacts either along the intrusive contact or below the intersection between the sill and the Bermejal intrusive contact. The mineralization in the Bermejal Underground deposit remains open in several directions.
