Geology Comments

Jun 25, 2010 (J Bongfelt) - The Lone Pine Prospect is situated within mafic to intermediate metavolcanic flows near the transition between the tholeiitic Upper Wabigoon Volcanics and the underlying tholeiitic to calc-alkaline Lower Wabigoon Volcanics. (OFR5723, p.231)

Lithology Comments

Jun 25, 2010 (J Bongfelt) - The Lone Pine Prospect consists of a deep shaft sunk on a 15m wide shear zone striking 084º/80ºN through fine- to medium-grained,massive, vesicular, mafic metavolcanic flows and mafic tuff, interbedded with thin layers of cherty interflow metasediments. The host rocks are moderately to intensely sheared, chloritic, carbonatized (iron carbonate, calcite), variably pyritic <1-5%, and commonly contain at least 5% disseminated, euhedral, coarse-grained magnetite. The shear zone hosts a 0.3-0.46 m wide quartz-iron carbonate-tourmaline vein which pinches and swells along its dip. Almond-shaped pods of quartz are surrounded by anastamosing sheared and fissile wall rocks. The vein contains chlorite, 1-2% disseminated pyrite, and some small flakes of visible gold that were observed by J.R Parker. Intense iron carbonate alteration is confined within an alteration halo which extends 0.3 to 0.6 m on either side of the vein. Narrow quartz stringers and veinlets occur parallel to the main vein and a few, narrow, horizontal veins extend from the main vein. Approximately 800m east of the Lone Pine property, Parker observed other strong shear zones (0.9-1.8 m wide), striking 064º-066º, through variably pyritic <3%, mafic to intermediate tuffs and flows hosting discontinuous stringers of white quartz veins containing iron carbonate and tourmaline. Wallrocks are chloritic, sericitic, and carbonatized (calcite) and commonly contain variable amounts of magnetite, tourmaline, and abundant epidote in thin veinlets and stringers.

Mineralization Comments

Jun 25, 2010 (J Bongfelt) - - Two grab samples of pyretic [<1%] quartz vein material, taken by J.R. Parker from the main vein, assayed 55 ppb gold and 140 ppb gold, while a grab sample of the altered, pyritic (1%), wall rock assayed 100 ppb gold. - Two grab samples of quartz vein material containing 2-3% pyrite, taken by Mr. Hoban near the bottom of the shaft, assayed 3820 ppb gold and 0.83 ounce gold per ton. - Two grab samples of quartz vein material taken from around the shaft by C.E. Blackburn assayed 0.03 ounce gold per ton and < 0.10 ounce silver per ton, and < 0.01 ounce gold per ton and 0.16 ounce silver per ton. - A grab sample of the quartz vein taken by S. Rivett assayed 0.13 ounce gold per ton. (OFR5723, p.231)
