GEOLOGICAL CONTEXT
Understanding the Tungsten Target
Tungsten deposits can have a relatively limited surface expression while remaining economically significant at depth. Principal geological settings include quartz-vein systems, skarns, greisen systems, and granite-related disseminated mineralization.
For DDT™ exploration, the principal detection target is tungsten-bearing mineralization expressed as anomalous tungsten (W) concentrations above regional background levels. Subsequent conventional geological verification would focus primarily on the principal tungsten ore minerals: Scheelite (CaWOâ‚„) and Wolframite ((Fe,Mn)WOâ‚„).
Growing industrial and strategic demand for tungsten increases the importance of identifying previously unrecognized tungsten-bearing systems and prioritizing prospective areas for detailed exploration.
STATEWIDE RECONNAISSANCE
Tungsten Signatures Detected Across Nevada
A reconnaissance-scale DDT™ investigation was conducted across the State of Nevada to identify anomalous intrinsic emission signatures associated with concentrations of tungsten-bearing minerals exceeding regional background values.
The interpreted DDT™ tungsten anomalies are presented below:
For validation and comparative interpretation, publicly documented tungsten deposits and occurrences were superimposed on the DDT™ survey results (Fig. 3). The comparison demonstrates a meaningful spatial correlation between a number of DDT™-identified anomalies and previously documented tungsten occurrences, supporting further evaluation of the detected signatures.

The comparison demonstrates a meaningful spatial correlation between a number of DDT™-identified anomalies and previously documented tungsten occurrences, supporting further evaluation of the detected signatures.
NEW EXPLORATION POTENTIAL
Prospective Targets Beyond the Known Deposit Map
Importantly, the statewide survey also identified a substantial number of prospective anomalies in areas where significant tungsten deposits are not presently documented in the public geological record.
These targets, shown by the designated exploration symbol on the survey maps, warrant higher-resolution DDT™ investigation and subsequent geological verification.
Based on their anomaly characteristics and spatial distribution, several of these areas may represent previously unrecognized tungsten-bearing systems with potential for economically significant mineralization at depth.
Conclusion
The Nevada reconnaissance demonstrates the potential of DDT™ to:
​
-
Detect tungsten-related anomalies over very large areas.
-
Identify prospective targets beyond currently known tungsten occurrences.
-
Reduce regional exploration areas to prioritized zones for detailed investigation.
-
Support subsequent geological, geochemical, geophysical, and drilling programs.
-
Identify potentially important mineralization where the surface footprint may be limited but the mineralized system may extend substantially at depth.

DDT™ provides an efficient regional screening approach for locating and prioritizing tungsten exploration targets before committing to higher-cost field exploration and drilling.
