Early Pipeline Prospects


K4 is a cluster of geochemical gold-in-soil anomalies, ranging from +40ppb Au to >300ppb Au, located within an inferred granitoid unit bounded by faults to the north and south. Two points were field evaluated resulting in the location of a sizeable field, 10mx 80m, of up to meter-scale quartz and tourmaline boulders and of a single decimeter scale boulder of grey vein material and silicified host? rock with pyrite, arsenian pyrite and chalcopyrite mineralization. A weak arsenic anomaly occurs in the area. The quartz and tourmaline boulders occur in an overgrown swampy area on the boundary of a farm. They exhibit multiple pulses of fluid flow with tourmaline laminations and brecciated tourmaline and quartz re-healed with quartz. Quartz phases are all white; no mineralization (sulphides) observed. The second location, 800m east, was grey quartz with sulphides as listed in both the vein material and host rock material but only a single boulber was found in a limited search. A single sample (15KDR-001) returned 10ppb Au.

The K-4 prospect may be indicative of an area of repeated structural activity and high fluid flow. The boulder trend is sub-parallel to the inferred north bounding thrust fault of the granitoid body. Although the single sample returned a low value this is the only location to date outside of previously drilled areas that sulphide mineralization has been observed in the field associated with grey quartz veining. Trending of the abundant quartz-tourmaline vein boulders appears to be 080.


K2 anomaly is generally linear anomaly potentially associated with a fault contact between granitoid and mafic volcanic units where the mafic units trend obliquely to the structural zone. The anomalous samples cover ~2,000m are associated with low hills with local multi-meter volcanic outcrops with millimetric quartz veins (trend ~080 and local cross veins 140/45), linear trends of multi-episode bull white quartz veins (trend 030, maybe 060) to the east and with low swampy ground farther to the west. No visible sulphides were observed in the veins.

This prospect may be an area reflecting repeated fluid flow and structural activity based on the volume and abundance of quartz trends with gold-in-soil values located in close proximity. The geophysical images indicate complex geometries of the underlying units.

Numerous bull white quartz vein fragments of sub-metre-scale sizes exhibiting massive to sugary to crushed and healed textures were discovered during field traverse. Weak gold in soil values, <50ppb Au, and weakly anomalous arsenic values were obtained from multi-element samples in the immediate area of the quartz veins. A single vein boulder trend was also located over a small hill from the initial find to the west and a single vein boulder train was found in the cocoa to the east. Total strike of quartz boulders is approximately 130m with a width of roughly 70m. No host rocks were found in the vicinity however to the south east abundant mafic volcanic float was observed with a single instance of a potential medium grained intrusive rock. Three soil samples were collected amongst the largest clusters of quartz boulders in the widest portion of the veining (15DOS001 – 003) which returned values of 67, 70, and 16 ppb Au, respectively.

This anomalous volume of veining associated with anomalous gold and arsenic values occurs near the inferred intersection of the northern end of a NNE geophysical trend and an inferred thrust fault separating the Tarkwaian from the Birimian. From the positioning of the boulders there appears to be up to three parallel veins at the widest part of the boulder train all of which are trending sub-parallel to the inferred thrust fault and are interpreted to be located in the footwall of this larger structure.

The veins fragments themselves did not indicate mineralization however the experiences in Ghana suggest that multistage bull quartz veins are indicative of zones of repeated structural activity and can be located close to mineralized structures. The low level gold values from the current limited sampling and the multi-element sampling along with a weak arsenic anomaly suggest potential for a mineralized structure in the area.
