Crestview Exploration Inc. announced the final assay results for the 2022 surface sampling campaign at the Rock Creek gold prospect in the Tuscarora Mountains of Elko County, Nevada. A total of 118 samples were collected from across the Rock Creek property, and submitted for precious metal and trace element geochemistry. As a reminder to the reader, the Rock Creek property consists of 74 unpatented lode mining claims, but is in close proximity to (as near as currently possible) Crestview's Divide and Falcon properties which comprise an additional 186 claims, for a total of approximately 2,009 hectares or 4,965 acres between the three.

Small historical prospecting occurred at all three properties, and more extensive historic mining occurred at Falcon and Divide. The surface sampling program has demonstrated wide-spread anomalous gold and silver, including nine samples with greater than 30 g/t Ag (including a sample of 121 g/t Ag), and 32 samples with greater than 0.1 g/t Au (including two samples with greater than 0.5 g/t Au). The 2022 sampling focused on epithermal quartz veins exposed in outcrop and historic prospect pits, and was undertaken in conjunction with 1:2,000 scale mapping.

A previous press release described results from the previous sampling program undertaken at Rock Creek, which summarized the previously collected 98 surface samples and highlighted two gold values over 0.5 g/t (0.543 g/t and 0.597 g/t Au) and several samples in the 0.1 g/t to 0.35 g/t Au range. The Rock Creek data also includes inherited gold assay results from historic sampling which included several samples greater than 1 g/t Au. The faults and quartz veins delineate major structural trends of mineralization and alteration at Rock Creek.

The quartz veins occur in several structural systems that dominate the entire Rock Creek property. Higher gold and silver grades correlate well with the presence of visible sulfides (arsenian pyrite) and jarosite in the quartz veins. Elevated arsenic and barium are ubiquitous in the samples, and there is a notable lack of mercury.

A statistical correlation was carried out on the 2022 Rock Creek surface sampling results. The strongest correlation with gold mineralization was arsenic and silver, and there was a notable lack of correlation with other predicted elements. NOTE: Several elements which were generally below the detection limit were left out of the correlation table.

Crestview is in the process of integrating this data with the other results from the 2022 field season, including the high-resolution mapping and the HSAMT survey lines to update drill targets for the 2023 season. QA/QC: Samples include both chip and grab, primarily from outcropping quartz veins; chip samples were collected using a rock hammer. Each sample was placed into a tight weave fabric type sample bag and transported to Paragon Geochemical assay lab in Sparks, Nevada.

The samples were prepared by Paragon to include drying at 100, crushing to 70% passing 10 mesh, riffle splitting 250g, and pulverizing to 85% passing 200 mesh. Equipment goes through Pre Operation checks for gold contamination. At the beginning of each sample job, wash rock blanks are crushed and pulverized.

Every 40 samples is checked for mesh size on the pre-split crushed sample as well as the pulverized material. The samples were analyzed for gold using a 30g fire assay, and a multi-element suite including silver was analyzed by Aqua Regia and ICP-OES. A prep duplicate (second pulp split from client sample) is run at random every 37 samples.

Results are compared to one-another with a precision tolerance generally 20% of each pair's mean. One certified reference standard (CRM) and one internal reference standard (IRM) is analyzed for each rack of 42 positions. Each rack also has a duplicate sample and a blank, resulting in 38 client samples per 42.
