Does anyone have information on El Picacho.I wonder if anyone can help me. Thus far I haven't come up with much other than what Millrock posted in their press release. Here is a link to USGS, https://mrdata.usgs.gov/sir20105090z/show-sir20105090z.php?id=3039 They reference the work done by Yale Resources 2008 but I couldn't get access to this company.

VANCOUVER, BRITISH COLUMBIA, June 8th, 2017 - Millrock Resources Inc. (TSX-V: MRO) ("Millrock") announces it has entered an option agreement to purchase the El Picacho project. The project consists of district-scale concessions that cover approximately 6,300 hectares, located in Sonora State, Mexico, 18 kilometres southwest of the San Francisco Gold Mine which is operated by Alio Gold Inc. The target is an orogenic gold deposit of similar scope to that present at San Francisco. The project was identified to Centerra Gold Inc. (“Centerra”) by Millrock, and Centerra has agreed that El Picacho will become a “designated project” under the terms of the strategic alliance agreement (“Alliance”) in place between the companies. The Alliance was announced
here in early 2017. Centerra has provisionally approved a US$460,000 exploration budget for 2017 for the El Picacho project.
Part of Yale Resources 2,620-hectare La Verde Project that on 6 contiguous exploration concessions (Yale Resources Ltd., 2008). Tentatively classified as a porphyry system based on geology (Lukas Zrcher, oral commun., 2008). Epidote-garnet tactite with scheelite, powellite, and oxide copper minerals. Development: W-bearing tactite discovered in the district in 1943. Three claims recorded: El Nublado, El Picacho, and La Florencia. Minor development (shallow pit),but no tungsten ore mined; gold produced at El Picacho and La Florencia. Geology: NW-strinking belt of discontinuous tactite outcropus surrounded by metalimestone and hornfel, probably underliain by granite. Granite crops out 200 m W of the limestone, separated from it by silicified volcanic breccia in contact with limestone along a pre-intrusive fault.
