VANCOUVER, British Columbia, May 16, 2018 (GLOBE NEWSWIRE) — Millrock Resources Inc. (TSX-V:MRO) (OTCQX:MLRKF) (“Millrock”) is pleased to report that a second round of drilling is beginning at the La Navidad gold project. The project, located in Sonora State, Mexico, 100 km north of the City of Hermosillo, targets orogenic, bulk minable, 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”). The core drilling program will consist initially of 1,650 meters in seven holes ranging from 150 to 250 meters in depth. These holes will target the large, strong, gold-in-soil anomalies previously identified at the Cobre and Crossover prospects. Recent trenching has confirmed bedrock gold mineralization at surface in these prospect areas. Additionally, at least one hole from the initial program completed in late 2017 will be deepened to test for further mineralization at the Anchor prospect. Results of that program were reported in a prior press release here. Contingent upon results of the upcoming drilling phase, the drilling program may be extended.
Millrock crews have been actively exploring the Cobre and Crossover prospects since early February. Detailed geological mapping with rock sampling (341 samples) was completed. It was found that the strongest soil anomalies occur in folded, faulted, Jurassic metasedimentary rocks in close proximity to diorite and monzonite dikes which follow pre-existing fault structures. Also, three lines of in-fill induced polarization geophysical surveys totaling 5.4 kilometers are in progress. The induced polarization survey has identified low-angle structures and stratigraphy conducive for orogenic gold deposition. An extensive program of surface trenching (1,398 meters in 16 trenches) and rock chip sampling (661 samples) has been completed. Results from the first eight trenches are reported below. A 0.1 parts per million gold cutoff was used to calculate the composite intervals. Geological relationships are not clear enough to accurately estimate true width of the anomalous zones reported.

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.
The scientific and technical information disclosed within this document has been prepared, reviewed and approved by Gregory A. Beischer, President, CEO and a director of Millrock Resources. Mr. Beischer is a Qualified Person as defined in NI 43-101.
