The aim of the recently completed geophysical campaign is to refine the shape (geometry) of a high chargeability anomaly identified in
Mineralisation in
A
The new IP survey confirms this early observation and highlights two wide and closely spaced high chargeability anomalies, located a short distance north-northwest of the Tabasquena 'new' shaft. The strongest one is observed in the western part of the new grid.
For both targets, the associated chargeability anomaly is deeply seated (> 250 to 300m) while their origin is linked to two distinct wide mineralized systems. The western anomaly appears to remain open laterally to the north and south within the property limits.
The report for the recently completed geophysical survey highlights three key areas - the North, Central and South domains which are discussed below.
North Domain
Two strong linear axes have been identified with the most recently completed survey. Axis IPT-2 is inferred to be orientated mainly N/S, with a lateral continuity exceeding 550 m which remains open northward. At first glance, this anomaly could indicate the northern continuity of the known mineralized system mapped in the Central Domain of the property. A second axis - Axis IPT-3 outlines one of the strongest chargeability anomalies identified to date and it is characterized by higher resistivity. The anomaly was delineated over 550 m and remains open laterally at both ends. This anomaly represents a new exploration target and may indicate the existence of a second mineralized vein system of deep origin.
Central Domain
It appears the eastern IP anomaly identified in the North Domain may be the main N-S IP anomaly within the Central Domain and through to the Southern Domain for a length of approximately 2.6 km. In the Central Domain, the associated chargeability anomaly is slightly weaker than the North and South Domains while having a slightly higher resistivity. Based on the available data, the delineation of the mineralized veins could be, at least partially, conditioned by the presence of sulphide or arsenide-rich silver minerals.
South Domain
Within the Southern Domain, Axis IPT-1 is more than likely associated with the main polarisable anomaly of weak to strong amplitude progressively delineated over 2.6 km by the successive 3D IP surveys completed since
Conclusion and Implications
The IP surveys completed on the Tabasquena project enhance the mineral potential of the northern third of the property. Of the two IP anomalies recently delineated in this area, one of them indicated by axis IPT-2 may directly relate to the northern continuity of the known mineralized vein system mapped in the center of property. The newly acquired data allows us to confirm its orientation as mainly N-S, with a lateral continuity exceeding 550 m and which remains open northward and at depth.
A key result of the recently completed survey, was the identification of a stronger IP chargeability anomaly indicated by axis IPT-3 which was identified immediately west of the main north south IP chargeability axis. At first glance, this could be the signature of a satellite mineralized vein system and as such, represents a new exploration target. This anomaly was delineated over 550 m and remains open laterally at both ends and at depth.
Below you will find three images, the first will help the reader better understand the north to south anomaly looking to the east. The second image provides a better understanding of the east to west dimension. The final image is a depth slice at the 400-metre level which shows the new northern domain anomaly increasing in size with depth. Once our current hole in the southern end of the property that is drilling below the 2.15 m hit of 664 g/t silver is completed we will immediately move the drill to the north end of the property to test the anomalies discussed above.'
