Dec 07, 2005 (G Seim) - The interval 350 - 395 ft. (45 ft.) averaged 260 ppb Au and includes the interval 370 - 372.5 ft. that returned 1429 ppb Au.
Jan 12, 2023 (Q Unknown) - Diamond drilling by Rosario Resources in 1980 resulted in DDH T80-9 intersecting anomalous gold values hosted in an ultramafic volcaniclastic (komatiite ??) unit. In all, the anomalous values averaged 260 ppb Au along a core length of 45 feet (13.72 metres) in the 350-395 ft interval. The host rock was cut by numerous qtz-py-calcite veins, with both diffuse (earlier) and sharp (later) boundaries. Contains about 1-2% py overall, both as v. fine disseminated grains and as thin coatings on fracture surfaces. The drill log reported that the 360-375 ft section contained six, 2-10 cm wide, c.g. qz veins. Occasionally contain py and greasy green chlorite.
