Mining of First Full Bench Containing the San Albino Vein Yields 1,002 Ounces Gold at a Diluted

Grade of 11.74 g/t Gold

Mako Mining Corp. (TSX-V: MKO; OTCQX: MAKOF) (“Mako” or the “Company”) is pleased to report grade

and tonnage results from mining of the first full bench containing the San Albino vein at its San Albino gold project

(“San Albino”) in northern Nicaragua. The bench mined consisted of two separate three-meter half benches between

616 and 610 meters above sea level (“Bench 610”) and contained 1,002 ounces Au and 1,511 ounces Ag within 2,654

tonnes of diluted vein material grading 11.74 g/t Au and 17.7 g/t Ag.

The 2,654 tonnes of diluted vein material are now sitting in a high-grade stockpile awaiting processing. An additional

3,710 tonnes of historical dump material grading 2.31 g/t Au were also mined from Bench 610. This stockpiled

historical dump material is expected to be used as initial mill feed during the ramp up to commercial production,

which is expected from January 2021 to early Q2 2021.

Akiba Leisman, Chief Executive Officer of Mako states that, “the grades encountered in Bench 610 are extraordinary

for any gold mining project, and especially for an open pit project like San Albino. Importantly, our operating team

over their many years of mining experience have developed selective open pit mining techniques and are

demonstrating that narrow high-grade structures can be mined open pit with limited levels of dilution. Although we

are still in the early days of mining at San Albino, this is a great start to our operations.”

Sampling, Assaying, QA/QC and Grade Estimation

Vertical channel samples respecting the geology were collected on 5-meter sections at approximately 4-meter spacing

using a gas-powered rock saw where the vein is competent, or a rock hammer where the rock is strongly fractured or

brecciated. Special attention is applied to standardize the width and volume of material taken using the rock hammer

or rock saw. The coordinates of the channel samples are surveyed using a total station surveying device.

Samples were kept in a secured logging and storage facility until such time that they were delivered to the Managua

facilities of Bureau Veritas, an independent assay lab, for sample preparation. Pulps were sent to the Bureau Veritas

laboratory in Vancouver for analysis. Gold was analyzed by standard fire assay fusion, 30-gram aliquot, AAS finish.

Samples returning over 10.0 g/t Au are analyzed utilizing standard fire assay-gravimetric method. The Company

follows industry standards in its quality assurance and quality control (“QA/QC”) procedures. Control samples

consisting of duplicates, standards and blanks were inserted into the sample stream at a ratio of 1 control sample per

every 3 to 4 samples. Analytical results of control samples confirmed reliability of the assay data.

The grade of the San Albino vein, low-grade and historical dump material were estimated using the inverse distance

cubed method (“ID3”) from 1-meter composite intervals respecting the geologic boundaries. Samples were capped

prior to compositing at 100 g/t Au in the San Albino vein, 7.0 g/t Au in the San Albino footwall, 4 g/t Au in the San

Albino hanging wall and 7.0 g/t Au in the Dump Material . Capping values were based an analysis of previous

diamond drilling results. The diluted grade of the San Albino vein was estimated using 3-D models of surveyed vein

boundaries and surveyed mined surfaces.

Steven Ristorcelli, CPG, a geologist and qualified person (as defined under NI 43 -101) has read and approved the

technical information contained in this press release. Mr. Ristorcelli is the Principal Geologist at Mine Development

Associates in Reno, Nevada working on the updated resource estimate for San Albino. Mr. Ristorcelli was at site in

February 2020, but has not been able to visit the site to personally review the ongoing grade control program;

however, he has reviewed the data from original certificates, QA/QC data, photographs of the geology, mapping and

Forward-Looking Information: Some of the statements contained herein may be considered “forward -looking information”

within the meaning of applicable securities laws. The forward-looking information contained herein is based on the Company’s

plans and certain expectations and assumptions, including the expectation that narrow, high-grade structures at San Albino can

be mined open pit with limited levels of dilution; that the average diluted grade will likely drift lower as more benches are mined

at San Albino; obtaining positive results from Mako’s reconnaissance exploration program on its recently acquired Potrerillos

Concession, including the various prospects on the Potrerillos Concession and in area directly adjacent to the northeast on t he

San Albino -Murra Concession; and the Company’s intention to complete a soil survey focusing on generating additional

exploration targets, followed by trenching and comprehensive structural/geological mapping, which are anticipated to be drilled

tested, in due course. Such forward-looking information is subject to a variety of risks and uncertainties which could cause actual

events or results to differ materially from those reflected in the forward -looking information, including, without limitation, that

the Company’s Preliminary Economic Assessment for the San Albino Gold Deposit dated April 29, 2015 (the “PEA”) is

preliminary in nature and there is no certainty that the PEA will be realized; the risk of economic and/or technical failure at the

San Albino project asso ciated with basing a production decision on the PEA without demonstrated economic and technical

viability; that the Company is not able to declare commercial production in early 2021;the Company does not continue to find

positive results from its reconna issance exploration program and proposed drilling on the concessions; that exploration and

assay results do not confirm continuity of mineralization as expected; political risks and uncertainties involving the Compan y’s

exploration properties; the inherent uncertainty of cost estimates and the potential for unexpected costs and expense; commodity

price fluctuations and other risks and uncertainties as disclosed in the Company’s public disclosure filings on SEDAR at

www.sedar.com. Such information contained herein represents management’s best judgment as of the date hereof, based on

information currently available and is included for the purposes of providing investors with the Company’s plans and

expectations regarding the exploration of the Potrerillos Conc ession and the potential for expansion of the mineralization at

San Albino, and may not be appropriate for other purposes. Mako does not undertake to update any forward -looking
