Hi-View Resources Inc. Receives Alteration Mapping, ASTER Multispectral, And EnMAP Hyperspectral Satellite Data For Toodoggone Portfolio Claims
Hi-View Resources Inc. announced the receipt of two complementary satellite alteration mapping reports for its Toodoggone Portfolio claims in British Columbia, both prepared by PhotoSat Information Inc. The ASTER Alteration Mapping Report and the EnMAP Regional Hyperspectral Exploration Targeting Report together provide an advanced multi-sensor characterization of hydrothermal alteration across the property and will directly inform ground-based exploration targeting for the upcoming field season. Dual-sensor coverage: Both ASTER multispectral and EnMAP hyperspectral satellite data analyzed using PhotoSat’s proprietary deep learning technology, providing industry-leading alteration mineral discrimination across the Hi-View Claims. 15 distinct alteration minerals mapped: The combined surveys identified and spatially mapped 15 individual alteration minerals, including key porphyry-epithermal indicator species. High-Al muscovite detected: The R-HET hyperspectral survey identified high-aluminum muscovite — a mineral that can serve as a vector toward the high-temperature core of a porphyry system — detectable only through hyperspectral technology. Iron oxide gossan assemblage confirmed: Jarosite, goethite, and hematite mapped across the property via EnMAP, consistent with supergene weathering of underlying sulfide-bearing zones, and corroborated by iron oxide gossans identified in the ASTER survey. Chlorite chemistry differentiated: Fe-chlorite and Mg-chlorite mapped separately, providing a potential vector toward hotter, more proximal parts of the hydrothermal system. The ASTER Alteration Mapping Report utilized data from NASA's Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite, which captures spectral information across Visible and Near Infrared (VNIR), Short Wave Infrared (SWIR), and Thermal Infrared (TIR) wavelength regions. PhotoSat applied its deep learning mineral mapping tools, calibrated against the USGS High Resolution Spectral Library, to multiple ASTER acquisition dates spanning 2001 to 2005 and supplementary Sentinel-2 imagery acquired in August 2025. The survey identified the following alteration minerals across the Hi-View Claims, with five returning mappable zones of 'probable' alteration, the highest confidence classification in PhotoSat's methodology: Silica (SiO2): Mapped at 75 m resolution with polygons of probable silica alteration delineated. Kaolinite: Mapped at 12.5 m resolution with polygons of probable kaolinite alteration identified. Sericite (fine-grained muscovite): Mapped at 12.5 m resolution with polygons of probable sericite alteration, indicative of phyllic alteration zones. Chlorite/Epidote: Mapped at 12.5 m resolution with polygons of probable alteration, consistent with propylitic alteration. Iron Oxide Gossans: Mapped at 10 m resolution via Sentinel-2, with probable gossan polygons suggesting weathered sulfide-bearing zones at surface. Alunite and Calcite: Detected but with no probable-grade response identified. The R-HET Report utilized data from EnMAP (Environmental Mapping and Analysis Program), a German hyperspectral satellite launched in 2022 that captures 244 spectral bands across VNIR and SWIR regions at approximately 30 m ground resolution. This enables a level of mineral discrimination not possible with conventional multispectral sensors, including the ability to identify minerals undetectable by ASTER or Sentinel-2, differentiate mineral compositions such as high-Al versus low-Al muscovite and Fe-chlorite versus Mg-chlorite, and detect subtle subpixel alteration signatures. The survey mapped 15 alteration minerals across the Hi-View Claims at 15 m resolution: Argillic /Clay Minerals: Kaolinite, illite, and montmorillonite were identified, collectively indicating argillic alteration environments ranging from advanced argillic zones proximal to the hydrothermal system to cooler, more distal margins. Micas /Phyllic Alteration: Muscovite (sericite) was mapped as relative abundance alongside high-, medium-, and low-aluminum compositional variants. The aluminum content of muscovite provides a spatial gradient, with high-Al muscovite indicating higher-temperature, more acidic processes that may vector toward the core of the porphyry system. Propylitic Alteration: Chlorite/epidote, Fe-chlorite, Mg-chlorite, epidote, and calcite were all identified. The differentiation of Fe- versus Mg-chlorite chemistry and the separation of epidote from chlorite provide additional vectoring capability toward the hotter, more proximal parts of the system. Iron Oxides /Gossanous Minerals: Jarosite, hematite, and goethite were mapped across the property, consistent with supergene weathering of sulfide-bearing zones and potentially indicative of gossanous material above underlying mineralization.
