VANCOUVER, BRITISH COLUMBIA, November 21, 2018 – 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”).
