San Marco Resources Inc. announced the first assay results from the newly discovered copper and silver mineralization at the Company's 100% owned Chunibas property, located approximately 160 kilometers east of Hermosillo, Sonora State, Mexico. As discussed in the Company's news release dated November 29th, 2017, and as a follow-up to the Company's grid soil sampling program, a strong copper/silver soil anomaly was defined in the northwest sector of the Chunibas project, an area that has seen little exploration by San Marco or past workers. Copper oxides have now been recognized and sampled from random outcrop exposures scattered over at least 1.2 kilometer of strike, and at least 100 meters of width. Additional sampling is ongoing in an effort to determine the full extent of mineralization, which remains open in all directions. Copper oxides (malachite and minor azurite) appear as the result of oxidation of chalcocite and bornite. Outcrop exposure in the area containing this new mineralization is generally poor. Sample points are dictated by irregularly spaced outcrops, represented by knobs, weather resistant ridges and small sub-crops, located within colluvium and soil covered foothills. At this point it does not appear that the mineralized outcrops are structurally related or created by preferential weathering, as copper mineralization has been found in several alteration regimes and rock types within this broad zone. Host rocks are presumed to be Laramide age intermediate volcanics, which have variable textures, andesite breccias; porphyritic andesite and vesicular -amygdaloidal andesites. Copper and silver mineralization is mainly hosted in the andesite breccia which are moderately to strongly altered by an assemblage of epidote>chlorite>quartz>calcite>specularite. Mineralization occurs mainly as disseminations, patches, cavity fillings, minor veinlets and hydrothermal breccias. Additional and pending exploration; Next batch of assay results of additional outcrop chip samples expected in approximately one week, Results of a Petrographic study to identify specific copper minerals expected in one week, Property exploration has resumed after the Christmas break. In addition to continued reconnaissance chip sampling, detailed channel sampling of known copper mineralized outcrops to be initiated, Induced Polarization (I.P.) as well as ground magnetic surveys are being considered to help define the boundaries of the system, as is trenching.
