MILLROCK ANNOUNCES ADDITIONAL TRENCH RESULTS;

CENTERRA GOLD AUTHORIZES DRILLING PROGRAM

EXTENSION AT LA NAVIDAD GOLD PROJECT, SONORA

STATE, MEXICO

VANCOUVER, BRITISH COLUMBIA, June 19, 2018 - Millrock Resources Inc. (TSX-V: MRO,

OTCQX: MLRKF) ("Millrock") is pleased to report the current drilling program underway at the

La Navidad gold project has been extended. The project, located in Sonora State, Mexico, 100

km north of the City of Hermosillo, targets orogenic, bulk mineable, run-of-mine, oxidized

deposits that could be processed by heap leaching.

Exploration work is being funded under an option to joint venture agreement by Centerra Gold

Inc. (“Centerra”). Originally, the core drilling program was to consist of 1,650 meters in seven

holes with further drilling contingent upon results. After a recent review, Centerra has authorized

a drilling program extension. The complete program will now consist of approximately 2,900

meters in 17 holes. Drilling is presently progressing on the tenth hole. The full program is likely

to be completed by the end of June, based on the rate of production realized in the first part of

the program.

The current drilling program is targeting the large, strong, gold-in-soil anomalies previously

identified at the Cobre and Crossover prospects in 2017. Recent trenching has confirmed

bedrock gold mineralization at surface in these prospect areas. Initial trench results were

reported here.

Following is a table of results of rock chip-channel samples from all 19 trenches excavated and

sampled. A gold cutoff of 0.1 grams per tonne gold was used to calculate the composite

intervals using a maximum of 3.0 meters of internal dilution. Geological relationships are not

clear enough to accurately estimate true width of the anomalous zones reported. Trenches

NAVTR-10, NAVTR-11, NAVTR-17 and NAVTR-18 did not contain significant anomalous

results.

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, the

companies have collaborated to execute a comprehensive exploration program. Centerra is

funding the exploration work to earn a majority interest in the project.

Quality Control – Quality Assurance

Millrock adheres to stringent Quality Assurance – Quality Control (“QA/QC”) standards. Drill

core and rock samples are kept in a secure location at all times. Rock samples are assayed at

the Bureau Veritas laboratory in Hermosillo, Mexico. Preparation and analysis methods are

described in further detail here. The sample preparation method code being utilized for the

current rock sampling program was PRP70-250. Analysis methods used include FA430 (30

gr/Fire Assay/ICP) and AQ-200 (Aqua Regia – ICP/MS). For every 20 rock samples, a blank

sample known to contain less than 3 parts per billion gold or a standard sample (Certified

Reference Materials) of known gold concentration, or a duplicate sample was also analyzed.

The Qualified Person is of the opinion that the results reported in this press release are reliable.
