Millrock Announces New Drilling Program at La Navidad Gold Project, Results from El Picacho Gold Project Sonora State, Mexico and General Corporate Update

VANCOUVER, British Columbia, Nov. 21, 2018 (GLOBE NEWSWIRE) — Millrock Resources Inc. (TSX-V: MRO, OTCQX: MLRKF) (“Millrock”) is pleased to report that another drilling program is underway at the La Navidad gold project in Sonora State, Mexico. The program will focus on the northwestern portion of the project. Four holes are planned at the El Tigre prospect, where gold has been detected by soil sampling in the vicinity of historic mine workings. Northwest trending high angle structures appear to control mineralization. Three holes are planned to test the El Chupadero prospect where alteration (decalcification and jasperoid replacement of limestone) points to the possibility of an intrusion-related gold deposit. In total, seven holes totaling 1,500 meters are planned. The exploration work is being funded under an option to joint venture agreement by Centerra Gold Inc. (“Centerra”).

At El Picacho, a drilling program consisting of 2007.8 meters in eleven holes was recently completed. Only narrow gold-bearing intersections were detected. The table on the following page indicates core sample assay results exceeding 0.1 gram of gold per tonne.

Quality Control – Quality Assurance
Millrock adheres to stringent Quality Assurance – Quality Control (“QA/QC”) standards. For the El Picacho and La Navidad drill programs 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.

PolarX Shares
Millrock recently sold 9,203,968 shares for A$497,014. While Millrock continues to be a strong believer in the Alaska Range Project, from an overall corporate standpoint it made sense to realize some profit, while still retaining significant upside exposure for shareholders. Millrock continues to hold 10,000,000 shares of PolarX and is entitled to a production royalty, an advanced minimum royalty, and certain milestone payments.

Liberty Bell Project
A wholly – owned subsidiary of Kinross Gold Corporation has provided notice to Millrock that it will terminate its option on the Liberty Bell project. The termination will be effective December 8, 2018. Millrock intends to seek another partner to test by drilling the numerous targets that have been developed by Kinross and Millrock over the past two years.
