Highlights
- The gravity survey confirmed a correlation between high-density anomalies and known mineralisation zones at the Linka Project.
- Multiple new gravity anomalies have been identified, expanding the pipeline of potential drill targets.
- Concealed targets beneath volcanic cover have been outlined, supporting preparations for the maiden drilling programme.
- Geological assessments aimed at evaluating new targets are expected to begin in April.
- The company is targeting the commencement of drilling in the June quarter.
Viking Mines Limited (ASX:VKA) has released results from an expanded ground gravity geophysical survey at its Linka Project in Nevada, identifying multiple new high gravity anomalies and expanding the drill target inventory. The survey has established a correlation between high gravity anomalies and known mineralisation.
Notably, targets identified beneath volcanic cover reduce uncertainty for the initial drilling programme and enhance the potential for new discoveries.
Survey Expands Exploration Scope
The recently completed geophysical programme was designed to extend understanding beyond the known surface mineralisation. The company aimed to locate additional targets beneath younger rock cover.
Three geophysical techniques were deployed to attain the stated objective, including ground gravity, ground magnetics, and GAIP trial. The ground magnetics assisted in the interpretation of the boundaries between the older sedimentary units and the source intrusion, and ground gravity dataset identified new targets.
Meanwhile, the GAIP trial has provided preliminary data to map subsurface lithology and structures, assisting in planning drill hole orientation. Evaluation of this dataset is ongoing.
Gravity Data Reveals New Targets
Newly processed survey data has identified multiple high gravity anomalies across the expanded survey area, which now includes the Linka Southwest extension. Notably, several of these anomalies align with previously identified mineralisation zones at Linka Main, Hillside, and Conquest.
Further anomalies detected across the survey area have added a substantial number of new prospects for detailed follow-up. This broader target base is expected to support future exploration programmes. Initial efforts will focus on ground-truthing of these new anomalies with the objective to determine the sources of these density contrasts.

The company plans to integrate field observations with geophysical data and mapped geology to assess and prioritise targets for drilling. Particular attention will be given to anomalies associated with the interpreted contact position between quartz monzonite intrusions and sedimentary limestone units.
Geological assessments aimed at evaluating these targets are scheduled to begin in April.
Drilling Plans and Next Steps
Viking Mines is fast-tracking the project via several workstreams and intend to commence drilling in the June quarter. Preparatory work includes field assessment and ground truthing of identified anomalies, sampling of historical tailings and stockpiles, and completion of a three-dimensional geological model.
The company is also preparing regulatory submissions, including a Notice of Intent to the Bureau of Land Management, alongside continued metallurgical testing and progressing toward a US OTC listing.
