MEGASTAR’S EFFORTS IDENTIFY MULTIPLE HIGH POTENTIAL TARGETS AT YAUTEPEC

Property lies within the known Oaxaca Au-Ag epithermal trend

Vancouver, BC, Canada, July 16, 2019 – Megastar Development Corp. (“Megastar”, or the “Company”)

(TSX-V: MDV; Frankfurt: M5QN), an early stage mineral exploration company focused on its properties

in Oaxaca, Mexico, is pleased to report on the Company’s preliminary exploration activities at its

Yautepec project; one of three properties that the Company is currently earning a 100% ownership in.

Headed by David Jones, Megastar’s exploration manager, a team of geologists performed two rounds of

reconnaissance mapping and geochemical sampling that have revealed widespread metal anomalies in

multiple areas on its Yautepec project. The exploration efforts are being focused on a 22-kilometer zone

consisting of a geological structure similar to those known to host bonanza type epithermal systems at

the nearby producing San Jose (Fortuna Silver Mines Inc., TSX: FVI) and Arista -Switchback (Gold

Resource Corp., NYSE: GORO) mines.

“It is remarkable to have defined such highly prospective geology so soon after the start of our field

program.,” said David Jones, exploration manager and director of Megastar. “The work to date supports

our initial interpretation and looks as promising as the early stages of other exploration programs in the

region which are now producing mines. The goal now is to expand known areas and discover additional

new targets. We await pending results with great anticipation.”

Laboratory results have been received from the first 146 rock chip samples, the more significant results

of which are compiled in the following table:

Se 7.80 12> 2 ppm Carbonate veins w/sulfides

Te 1.06 3>0.20 ppm Quartz vein

Tl 2.75 9 > 1 ppm Breccia: silicified and veined

These highly anomalous results are from quartz veins, silicified breccias, and siliceous sinter deposits in

multiple areas that, to date, have seen little detailed evaluation. They are found in multiple distinct

centers along a north-northwest striking 8.4 km trend of prospective rocks that trace a volcanic caldera

margin.

An additional 175 rock samples are currently undergoing laboratory analysis, results for which will be

announced in a subsequent news release.

Company President & CEO, Dušan Berka commented: “I am very pleased with the results to date and

with the firming metal prices, these truly are exciting times for Megastar shareholders and investors.

Megastar will continue to be aggressive in exploring and advancing its land holdings, in order to

establish their potential quickly and efficiently.”
