Tempus Resources Ltd (ASX:TMR, TSX-V:TMRR)’s first-ever high-resolution airborne geophysics survey over the entire Elizebeth Gold Project in southern British Columbia, Canada, has increased the footprint and depth extensions of gold mineralisation at the site.
The Blue Creek Porphyry intrusion, which hosts the high-grade gold mineralisation at Elizabeth, likely covers an area four times the size of its previously known extent and appears to extend at least 2 kilometres below surface (around 10 times deeper than currently drill tested).
Two additional anomalies have been identified as potential intrusive bodies similar to the Blue Creek Porphyry (showing strong continuity along strike and at depth).
“Much larger” gold system than previously thought
Tempus president and CEO Jason Bahnsen said: “The results of the geophysical surveys show that the intrusive system that hosts the gold veins at Elizabeth is much larger and extends much deeper than previously thought.
“There are also two additional large-scale anomalies within the project licence - the results highlight the potential for Elizabeth to complement its high-grade nature with very large scale.”
In June, Precision GeoSurveys Inc. was contracted to complete airborne magnetic and radiometric surveys over the Elizabeth Gold Project and completed 97 lines for a total of 735 line-kilometres.
Over the Elizabeth Main and Elizabeth East Zones a line spacing of 100 metres was flown to increase the resolution and detail over these zones and the geophysical surveys identified the Blue Creek Porphyry, which is the known host of the high-grade Elizabeth gold-quartz veins, as a relative magnetic low anomaly within the Shulaps Ultramafic Complex.
From this correlation of geology and geophysics, it was determined that the Blue Creek Porphyry, originally explored and mapped to approximately 1.1 square kilometres in size, is likely much larger.
This new geophysical data and interpretation of the Blue Creek Porphyry also extends at depth, revealing a robust intrusion extending at least 2 kilometres deep.
Elizabeth drilling update
In the meantime, diamond drilling continues at the Elizabeth Main Project, with 11 holes, for around 2,850 metres, completed to date.
Eight holes have had samples submitted to the lab to date.
Assays for the first four holes were submitted to SGS Laboratories for assay on June 24.
Completion of the initial assays has been subject to delays due to heavy volumes at the lab but are expected to be received in early August.
