VANCOUVER, BRITISH COLUMBIA, May 16, 2018 – 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 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”). 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.
