Summa Silver Corp. reported results from a geological mapping and soil geochemical survey at its 100% owned high-grade silver-gold Mogollon Project, New Mexico (the ?Mogollon Project?). Geological Mapping Program: A detailed geological mapping program was recently completed north of Mineral Creek across the northern extension of the Mogollon mining district.

Mapping covered 16 km2 and was aimed at providing further geological and structural context for high-grade rock-chip samples collected during a recent reconnaissance-style prospecng program. Samples with grades up to 8,475 g/t silver equivalent (8,373 g/t Ag, 5.39 g/t Au and 4.43% Cu) from the Silver Bar vein, 3,652 g/t silver equivalent (221 g/t Ag, 39.3 g/t Au and 0.83% Cu) from the northern extension of the Queen vein, and 3,046 g/t silver equivalent (812 g/t Ag, 3.80 g/t Au and 18.4% Cu) from the northern extension of the Great Western Vein system highlight the high-grade potenal of the district north of Mineral Creek in an area lacking historic exploraon and development. Based on these prospecng results it was considered a priority to refine the geological model for the extensive vein systems. The historic USGS geological map was used for reference and many lithological contacts, faults and veins were refined, based on detailed and small-scale mapping.

All mapped faults are locally associated with mineralized epithermal-related veining, stockworks or vein breccias, with alteraon halos composed of quartz + clay. Veins are generally steeply dipping, greater than 60o, and the two dominant vein sets, Queen and Green Western strike to the northeast. The intersecon of these vein sets with northwest oriented structures are considered priority targets highlighted by boiling textures and potenal blow-out structures.

Importantly, the distribuon and strike-extents of many key veins north of Mineral Creek have been extended beyond the limits of past mapping. These areas represent compelling target areas for connued sampling, including detailed channel sampling of exposed veins. A ground-based geophysical survey (e.g., CSMAT) is also being planned to beter define the sub-surface potenal of many of the exposed high-level veins as alteraon intensity may increase with depth.

Soil Geochemical Program: The Phase-1 soil geochemical survey consisted of 1,680 samples across two grids, the northern Fanney grid and the southern Deadwood grid. Both grids comprised north-northeast oriented lines spaced 100 m apart with samples spaced 50 m along the lines as well as east-west oriented lines spaced 100 m apart with samples spaced 25 m along the line. The later set of lines primarily covered the north-trending Queen vein and fault system.

Samples were analyzed using a tailored portable Xray fluorescence spectrometer (pXRF) workflow to measure elemental concentraons from prepared sample mounts in the field. Samples were prepared and analyzed daily. The goal of the Phase-1 soil geochemical survey across parts of the Mogollon Project were twofold: Investigate the soil geochemical footprint of known veins.

These new data reveal a strong spaal correlaon between known high-grade Ag-Au, epithermal-related veins, and anomalous arsenic in overlying soils. The distribuon of the known veins is primarily inferred from geological mapping of scatered outcrops as well as mapping of vein-exposures in historic surface disturbances. Rock geochemistry also suggests a strong correlaon between precious metals and arsenic, suggesng that arsenic, as well as Cu, Pb and Zn, are suitable pathfinders for silver and gold mineralizaon in the surficial environment.

These elements are rounely measured with a pXRF. The Last Chance vein of the Deadwood grid is spaally associated with strong arsenic-in-soil anomalism. Zones of strongly anomalous soils across the Fanney Grid broadly trend east-west and are locally spaally associated with the Johnson-Trilby, Independence-Anaconda, Fanney and Homestake veins.

Most samples collected proximal to the dominant, north-trending Queen vein were also strongly anomalous in pathfinder elements. These results suggest that high-grade epithermal veins of the Mogollon district generate strongly anomalous and proximal arsenic-in-soil anomalies. This relaonship can therefore be used to idenfy previously unknown and potenally concealed veins in areas lacking exposure and historic exploraon and sampling.

Use the soil geochemical data to inform bedrock mapping below soil cover. Key trace element raos, known to differenate key volcanostragraphic units at Mogollon based on whole-rock lithogeochemical data, in the soil samples highlight most lithological contacts across the sampled grids. The Ti/Zr rao in soils specifically differenates footwall and hanging wall volcanic units host to the Queen vein, near the Consolidated mine, the Fanney and Independence veins, and the Last Chance veins.

This strong spaal relaonship between soil geochemistry and mapped lithologies suggest that soils are relavely in-situ and that soil-grids across areas lacking detailed bedrock, can be used to assist with geological interpretaon and vectoring to prospecve rock units. A project-scale soil geochemical grid has been planned to cover the rest of the Mogollon Project, including the gaps in coverage south of Mineral Creek near the centre of the Mogollon mining district and most of the recently staked ground north of Mineral Creek. A selecon of samples from key lines will also be submited to the lab for low-detecon ICP-MS analyses to beter define trends in key elements such as silver, gold and anmony.

These data will be used to refine the exploraon models and generate new drill targets.
