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.
