Leagold Reports Drilling Results and New Drilling Program for Bermejal Underground

April 12, 2017 Download PDF

Vancouver, April 12, 2017 - Leagold Mining Corporation (TSX-V: LMC) ("Leagold" or the "Company") is pleased to report drilling results at its recently acquired Los Filos Gold Mine with highlights of 18.5 grams per tonne ("gpt") over 29.2 metres and 12.4 gpt over 21.6 metres, including 17.6 gpt over 9.2 metres (all capped grades and true widths; see Table 1) from the oxide zone of the Bermejal Underground deposit. These drill holes were part of an infill and geotechnical program completed in Q1 2017 and were not included in Leagold’s recently filed NI 43-101 Technical Report for the Los Filos Mine.

Neil Woodyer, CEO stated "The infill drilling results are exceptional and confirm the widths and grades in the widest and higher grade portion of the Bermejal Underground deposit. We are initiating a $7.7 million step-out and infill drilling program of 56,000 metres to add more resources to Bermejal Underground. Los Filos currently operates two open pit mines, Los Filos and Bermejal, and one underground mine at Los Filos. The Bermejal Underground project presents the opportunity to develop a second underground mine to both expand gold production and extend mine life. The results to date confirm the high quality and significant exploration upside potential of Bermejal Underground."

Recent Results

Gold iron-oxide skarn mineralization is located along contacts between intrusive and carbonate host rocks and provides extensive opportunities at Los Filos for identification and delineation of additional resources. The mineralization in the Bermejal Underground deposit remains open in several directions.

The infill drilling program was comprised of seven holes (a total of 5,570 metres) designed to intersect the Inferred Resources for conversion to an Indicated classification in a high-grade portion of the Bermejal Underground deposit. This high-grade zone of oxide mineralization is along a vertical contact with the Bermejal intrusive and contains the bulk of the mineral resources within the Bermejal Underground deposit (Figures 2 and 3). These resources are located below the intersection of a sill with the Bermejal intrusive (Figure 3).

A further six geotechnical holes (3,554 metres) were completed to investigate underground development and mining options as part of advancing the project. Two of the geotechnical holes intersected mineralization along the contacts of the sill and at the intrusive/carbonate contact and are reported here (Table 1). Three of the holes were not drilled in the area of mineralization and assay results are pending for the final geotechnical hole.

New Drilling Program

Leagold is commencing a $7.7M drilling program in Q2 2017 of 56,000 metres, targeting step-out and infill drilling, to expand the known Bermejal Underground resource base and to increase resource classification in support of future feasibility level studies and capital investment decisions (Figure 4). Drill holes are planned to intersect oxide mineralized zones at the steeply dipping to vertical contact of the Bermejal intrusive with carbonate as well as the upper and lower contacts of the sill.

The program includes the use of reverse circulation (RC) drilling in the upper portions of holes followed by diamond drilling "tails" to the end of hole in order to provide more rapid completion of the program and to reduce drilling costs. The program will be completed in 2017.

Additional opportunities for drilling are evident on the west side and the southeast trend of the contact of the Bermejal Intrusive.

Bermejal Underground Project

The drilling results are reported for the oxide zone located at the contact of intrusives with carbonate rocks. Mineralization is gold in iron oxides and is amenable to heap leaching (current recoveries for similar material is 80% from the existing heap leach operation).

The Bermejal deposit extends to at least 600 metres below the current Bermejal Open Pit and has been examined as an underground opportunity due to the high strip ratio that would be required for an open pit to mine the entire mineral resource. The Bermejal Underground resource, as reported in the March 1, 2017 Technical Report and PEA ("Preliminary Economic Assessment") report, is presented in Table 2. The Bermejal Underground deposit is entirely below and separate from the current Bermejal Open Pit Mineral Reserves.

Bermejal Underground Measured and Indicated Mineral Resource consists of 4.74 million tonnes at 6.65 gpt Au containing 1.012 million ounces plus Inferred Mineral Resource of 4.17 million tonnes at 5.05 gpt Au containing 0.678 million ounces (Stantec, March 1, 2017).
