MILLROCK REPORTS DRILL RESULTS FROM LA NAVIDAD

GOLD PROJECT, SONORA STATE, MEXICO AND

CORPORATE DEVELOPMENTS

VANCOUVER, BRITISH COLUMBIA, August 9, 2018 - Millrock Resources Inc. (TSX-V: MRO,

OTCQX: MLRKF) ("Millrock") is pleased to report that the second phase of core drilling on the

La Navidad gold project has been completed. The program was designed to test geological

targets identified through soil and rock sampling, geophysical surveys and trenching. The drill

holes targeted the Crossover and Cobre prospects. The Navidad project, located in Sonora

State, Mexico, 100 km north of the City of Hermosillo, targets orogenic gold deposits and is

being funded under an option to joint venture agreement by Centerra Gold Inc. (“Centerra”). In

total, 2,969 meters in 14 holes were drilled. Additionally, Hole NV-010 initially drilled in the first

drilling campaign was deepened. The table following on the next page indicates significant and

anomalous drill intersections for gold in grams per metric tonne (“g/t”). Highlights of the program

with two different cutoff grades are shown on the table immediately below:

(using 0.05 g/t cutoff)

NV-013 12.5 meters 1.14 g/t gold 14.0 meters 1.03 g/t gold

NV-014 8.0 meters 0.46 g/t gold 20.3 meters 0.22 g/t gold

NV-015 8.7 meters 0.43 g/t gold 8.7 meters 0.43 g/t gold

NV-019 7.9 meters 2.34 g/t gold 10.2 meters 1.83 g/t gold

NV-021 17.4 meters 1.61 g/t gold 64.2 meters 0.57 g/t gold

NV-024 9.2 meters 0.71 g/t gold 15.1 meters 0.46 g/t gold

Millrock President & CEO Gregory Beischer commented: “Some strong results were obtained in

this program from the Crossover and Cobre prospects with anomalous gold over significant core

intervals. More drilling will be necessary to determine whether there is continuity between the

discrete zones of mineralization intersected.”

Note: The mineralized intervals reported in the two table in this disclosure are down-hole,

measured thickness. Based on initial interpretations it appears the mineralized zones

intersected dip shallowly to the north at 15 degrees. However, there is not enough geologic

control at this point to verify the interpretation and therefore to make an accurate estimate of

true width with confidence. In particular, it is noted that hole NV-021 may have been drilled sub-

parallel down the dip of several gold-mineralized structures. For the composited values

thickness of 3.0 meters was used. See note below concerning quality control – quality

Since forming an option to purchase agreement with the underlying mineral right owner of La

Navidad in June 2017, and a simultaneous option to joint venture agreement with Centerra,

Centerra and Millrock have collaborated to execute a comprehensive exploration program. Initial

surface exploration results were reported in this press release and results of the first drilling

program was reported in this press release by Millrock. Centerra is funding the exploration work

to earn an interest in the project.
