Toogood Gold Identifies Promising Geophysical Targets at Table Mountain Project

Toogood Gold Corp. has identified multiple geophysical targets along kilometre-scale corridors at its Table Mountain Gold-Silver Project in Nevada. The company’s integrated survey results from ground gravity and drone magnetic surveys, together with initial controlled-source audio-frequency magnetotelluric (CSAMT) surveying, have revealed promising targets that could lead to significant drilling opportunities.
The gravity survey delineates a broad positive anomaly, approximately four kilometres by two kilometres, that closely coincides with the hydrothermal alteration footprint of the project. Field observations document intensely silicified volcanic rocks, silica-cemented hydrothermal breccias, and extensive veining within this footprint. The UAV magnetic survey delineates multiple kilometre-scale magnetic lows and pronounced magnetic gradients associated with the Widowmaker, Pacifico, and ENE-WSW structural corridors. These features overlap discrete gravity highs and coincide with mapped faults, intense silicification, and epithermal veins.
The combined response of the gravity and magnetic surveys is consistent with increased rock density through silica addition and pore-space filling, accompanied by hydrothermal destruction of magnetite, according to research by Allis (1990). The geological support for these targets is strong, as they coincide with major mapped faults, intense silicification, hydrothermal breccias, and epithermal Au-Ag quartz veins.
Initial CSAMT results from Zonge International, which is conducting approximately 15 line-kilometres of surveying across priority target trends, have helped define the Widowmaker, Pacifico, and ENE-WSW corridors at depth through prominent resistive features and sharp resistivity contrasts. Their interpreted positions align with epithermal veins, intense alteration, previously reported rock geochemistry, and coincident gravity highs and magnetic lows, strengthening their priority for maiden drilling.
The ground gravity survey, comprising 1,688 stations on a 100-metre by 100-metre grid, was completed by Magee Geophysical Services LLC. MWH Geo-Surveys International Inc. completed approximately 780 line-kilometres of UAV magnetic surveying along northwest-southeast lines spaced 25 metres apart. Wave Geophysics is responsible for final processing and three-dimensional inversion modelling of the gravity and magnetic datasets. Two-dimensional products include complete Bouguer and residual gravity maps, total magnetic intensity and reduced-to-pole magnetic maps, and vertical-derivative and tilt products.
Zonge International is conducting approximately 15 line-kilometres of scalar CSAMT surveying, with the initial Line 2 section using 50-metre receiver dipoles and a 1,500-metre transmitter bipole. Results are presented as a two-dimensional resistivity inversion model.
The company will complete the CSAMT survey and integrate the results with geological mapping, soil and rock geochemistry, gravity, and magnetics to refine drill targets. Initial targeting will prioritize mapped veins, fault intersections, bends, and areas of intense alteration, with geophysical results helping assess their subsurface geometry.
Toogood Gold Corp. is focused on the discovery and advancement of high-grade gold systems in tier-one mining jurisdictions. The company has an option to earn a 100% interest in a large, undrilled low-sulphidation epithermal system with extensive surface alteration and multiple mineralized vein exposures at the Table Mountain Project in Nevada.
