STAGE ONE RESULTS
What the Survey Found
A Stage One survey using OGD's Direct Detection Technology™ has identified numerous primary anomalies associated with gold-bearing formations across a 151 km² study area in the state of Sonora, Mexico. The results confirm the presence of gold mineralization and point to potential commercial significance within the surveyed area.
Rather than relying on indirect geological indicators, DDT™ is designed to detect the resource signature itself. Applied to the Sonora study area, this approach identified gold expected to occur within all detected primary anomalies, at levels above background values — a first-pass confirmation that the target mineral is present, not just geologically plausible.

Applied to the Sonora study area, this approach identified gold expected to occur within all detected primary anomalies, at levels above background values — a first-pass confirmation that the target mineral is present, not just geologically plausible.
Based on these results, DDT™ Stage Two field studies are recommended as the next step. Stage Two work is intended to refine anomaly boundaries, verify GPS locations on the ground, rank anomalies by intensity, define the most prospective zones with greater precision, and identify optimal locations for initial drilling.
From 151 km² to the Right Targets
The core value of the Stage One survey lies in how much it narrows the field. Of the full 151 km² study area, nine priority zones — totaling approximately 19 km² — were identified and classified as Category I or Category II, with Category I representing the highest exploration priority.
This classification draws a clear line for where further work should concentrate: the nine zones are recommended for continued investigation, while the remaining area outside them is not considered commercially prospective at this stage.
Beyond the current study boundary, an additional area of approximately 10 km² to the south shows highly prospective anomalies comparable in strength to the Category I zones already identified. Should licensing be secured for this area, Stage Two field studies there are strongly recommended.
Before extending Stage Two work southward, however, the recommended path is to first conduct a Stage One study over roughly 25 km² beyond the current southern boundary. This step would establish the full extent of the anomalies in that direction, after which Stage Two could be carried out across the complete prospective area — rather than committing field resources before the target's true boundaries are known.
What Comes Next
The Sonora project illustrates the staged logic behind the DDT™ methodology: a wide-area Stage One screening narrows a large territory down to a small set of high-confidence targets, and Stage Two field verification — GPS-confirmed anomaly ranking, boundary refinement, and drill-site selection — follows only where Stage One has already indicated commercial promise.
For Sonora, that means two parallel next steps: advancing Stage Two field studies across the nine confirmed priority zones, and extending Stage One screening ~25 km² south to fully map the adjacent opportunity before committing further field resources there.
