- 2020 soils survey expands anomalous gold values to over 3,000 metres of strike length in prospective Junction Creek Sandstone
- Gold values 0.52 to 6.28 g/t from underground grab samples
- Drill program permitting underway
The current program successfully expanded the size of the gold in soil anomaly footprint to over 3,000 metres along the prospective Junction Creek Sandstone. The anomalous values range from 10 ppb – 460 ppb gold. Limited sampling of both the stratigraphically lower Entrada, and stratigraphically higher Dakota, sandstones returned weakly anomalous gold values opening up two new prospective units with potential to host gold mineralization. In light of the successful expansion of the soil geochemical anomalies, Alianza has commenced permitting an initial drill program to test the extent of gold mineralization in the Junction Creek Sandstone and other targets that may be identified.
An underground structural mapping and sampling program was also completed and revealed that two types of black bitumen veins and fracture fills along with resistant brown coloured shears are associated with gold mineralization. Gold-bearing veins, fracture fills and shears dominantly strike north-east and dip to the south east. This orientation is approximately orthogonal to the axis of an anticline centred over Twin Canyon. These types ofmineralized veins returned 1.15 – 5.66 g/t gold from grab samples,while the immediate wall rock surrounding them consisting of disseminated bitumen-spotted sandstone and hard brown concretions also returned highly anomalous values ranging from 0.52 – 6.28 g/t gold. A sample of white, resistant deformation bands and wall rock with a north-west strike parallel to the strike of the anticline returned 1.45 g/t gold.
“We are excited by the results of our sampling programs at Twin Canyon,” stated
Alianza launched the 2020 fall program to follow up the successful first field program at Twin Canyon. Highlights of that work included expansion of the property to over four square kilometres, definition of a large gold in soil anomaly ranging from 20 – 460 ppb gold and measuring over 1,900 metres long by 100 metres wide, and the discovery of new areas of gold mineralization through limited prospecting. Results included 0.208 g/t gold in a grab sample of bitumen-spotted altered Junction Creek Sandstone.
Gold mineralization occurs at Twin Canyon in areas where the host sandstone unit is bleached and spotted with bitumen, with small amounts of limonite after pyrite. Optical and microprobe work carried out on mineralized samples indicate a direct gold – bitumen association raising the novel possibility that the mineralizing process at Twin Canyon is related to those associated with petroleum basin development.
