VANCOUVER, Nov. 28, 2018 /CNW/ - Leagold Mining
Corporation (TSX:LMC; OTCQX:LMCNF) ("Leagold" or the "Company") reports 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 (see Table 1) and Measured and Indicated mineral resources total 39.3 Mt grading
1.0 g/t and containing 1,259 koz of gold (see Table 2). The results at RDM represent a net reduction of 41 koz since the
2017 reserve estimate (effective date of December 31, 2017) 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 (see Table 3), representing a net decrease of 58 koz since the 2017 reserve estimate (effective date of December 31, 2017). 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 (see Table 4).
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.

At Fazenda, Leagold has also completed a 38-hole underground drill program totalling 5,964 metres with the objective of
identifying new resources and reserves and upgrading Inferred Mineral Resources to the Indicated category. The program
focused on two underground drilling targets accessed from the C-ramp and one target from the E-ramp. Drill holes in the
C-ramp area intersected mineralization on extensions to the principal structures including the CLX and Canto sequence
mineralization. A preliminary assessment of the drilling results shows an opportunity to increase reserves and resources,
however, further analysis is required with updated mineral resource estimates anticipated in 2019. Table 5 below summarizes
mineralized intervals from 22 of the 31 holes from the recent drilling program in the C-ramp target areas. These results
have not yet been included in the current Mineral Resource estimate. Drilling of 7 holes in the E-ramp target area was not
successful.

Technical Disclosure Regarding Fazenda Drilling Results
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.
Samples from this 2018 program were sent to the mine site laboratory for sample preparation and analyses by 50-gram fire
assay. The laboratory has accreditation to ISO Standard 17025:2005. A full quality control and quality assurance
(QAQC) program and protocols are in place and are aligned with best practices including regular insertion of certified reference
standards, blanks, and duplicates. External check assays are sent to third party independent laboratories on a regular
basis. QAQC data is reviewed on an ongoing basis and reported monthly.
Doug Reddy, P.Geo, Leagold's Senior Vice President – Technical Services, is a Qualified Person
and has verified the data disclosed, including the sampling and analytical data, and concludes that there are no known drilling,
sampling recovery or other factors that could materially affect the accuracy or reliability of the drilling data.

Cautionary Note Regarding Forward Looking Statements
This news release contains "forward looking information" or "forward looking statements" within the meaning of applicable
securities legislation. All statements other than statements of historical fact, included herein, including statements relating
to anticipated mine life, exploration potential and anticipated exploration success at each of the RDM and Fazenda mines are
forward looking statements. Generally, these forward looking information and forward looking statements can be identified by the
use of forward looking terminology such as "plans", "expects" or "does not expect", "is expected", "budget", "scheduled",
"estimates", "forecasts", "intends", "anticipates" or "does not anticipate", "will continue" or "believes", or variations of such
words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur"
or "be achieved". Statements concerning mineral resource estimates may also be deemed to constitute forward looking information
to the extent that they involve estimates of the mineralization that will be encountered. The material factors or assumptions
used to develop forward looking information or statements are disclosed throughout this document.
Forward looking information and forward looking statements, while based on management's best estimates and assumptions, are
subject to a variety of known and unknown risks, uncertainties and other factors that may cause the actual results, level of
activity, performance or achievements of Leagold to be materially different from those expressed or implied by such
forward-looking information or forward looking statements, including but not limited to: risks related to international
operations; risks related to general economic conditions and credit availability, unanticipated reclamation expenses; changes in
project parameters as plans continue to be refined; fluctuations in prices of metals including gold; fluctuations in foreign
currency exchange rates, increases in market prices of mining consumables, possible variations in mineral reserves, grade or
