December 21, 2021 Crestview Exploration Announces Updates to Surface Sampling and Mapping at the Castile Mountain Gold Prospect in Tuscarora, NV
Calgary, Canada December 21, 2021 – Crestview Exploration Inc. (CSE: CRS, Frankfurt: CE7) (“Crestview” or “the Company”) is pleased to announce the results of the 2021 mapping and sampling program at the Castile Mountain gold prospect in Tuscarora, NV. Crestview’s Castile Mountain prospect was mapped at a 1:2,000 scale, and additional surface chip samples were collected. The 2021 sampling program at Castile is comprised of 15 surface samples taken from faulted and fractured zones with strong alteration and mineralization envelopes (silicification and iron oxides).
Justin Lowe, VP Exploration, commented “our 2021 mapping and sampling at Castile has further demonstrated the target concept for the property, with several of our samples containing anomalous gold including one at greater than 0.5 g/t Au. Looking forward, a key aspect for a successful drill program at Castile will be intersecting the unconformity between the surface volcanics and underlying metasedimentary basement. To this end, we are looking into conducting a geophysical survey ahead of our planned 2023 Reverse Circulation drilling program.”

Castile Mountain   The geologic mapping conducted at Castile indicates that drilling, both shallow and deep, is warranted to pin down structural intersection zones and the unconformable contact between the Tertiary volcanic rocks with the Palaeozoic basement.
Tertiary volcanic rocks at Castile Mountain are represented by andesite breccias (Tpx) and minor andesite lavas (Tpa; Map 1). Palaeozoic siliciclastic rocks are exposed about 3 kilometres SW of Castile. Alteration and mineralization are structurally controlled along faults and fractures.  A strong NW-trending, NE-dipping structural zone, with a minimum width of about 500 meters, crosscuts the Tertiary volcanics and is assumed to be a depositional site of precious metals. This primary fabric is intersected by NE-trending, SE-dipping structures of variable widths (~50-70 meters). These intersection zones are spatially associated with alteration and iron oxides. 
Volumetrically the most important type of alteration that affects the andesite breccias is a pervasive illitic assemblage preserving most of the original textures. Commonly, the andesite breccia is vuggy (pitted) due to the removal of altered feldspar phenocrysts. Weak propylitization only affects the andesite lavas, although in some locations the lavas are altered to an illitic assemblage with strong iron oxides proximal to structures.
Iron oxides (exotic jarosite and hematite with minor late goethite) are abundant across the property. The iron-oxides proportions vary across the property from approximately 70 % jarosite and 30 % goethite to approximately 90% goethite and 10 % hematite.   An additional 15 samples were collected at the Castile Mountain gold prospect (Map 2) in 2021, bringing the total number of surface samples collected at Castile to date to 34, with 17 samples containing greater than 0.1 g/t Au including 3 samples greater than 0.5 g/t Au.
