Northwestern Ontario Gold Projects

Northwestern Ontario Gold Exploration
 
 
Argo Gold Inc. has 100% ownership in six high-grade gold exploration projects in the north and northwestern regions of Ontario.
Argo Gold’s flagship gold exploration the Uchi Gold Project is situated in the Birch-Uchi Greenstone Belt, which hosts the recent multi-million ounce Springpole gold deposits.
 
Uchi Gold Project (Au)
 
 
 
The Uchi Gold Project (which includes the Woco Gold Prospect) is located west of Uchi Lake at the south end of a series of historical gold mines (Uchi Mine) on a north-south trend.
  • High-grade gold mineralization was discovered at the Woco Prospect in 1993 by St. Jude Resources Ltd. Two drill programs identified a mineralized quartz vein extending over a distance of 100 m along strike and 150 m depth.
  • The high-grade core plunges north at -60o and is cut-off at the south end by a late E-W fault. The offset continuation has not been discovered.
  • Gold mineralization occurs as fine specks of gold disseminate in the quartz and closely associated with hairline fractures in the quartz;
  • The Woco Vein is located in a high strain zone that occurs at the contact between a competent felsic metavolcanics (dacite) and pillowed mafic metavolcanics (basalt).
  • The Woco Vein and structure trend northerly and dip steeply west occurring 300 m west of the Uchi Break, a regional N-S structure hosting a series of past gold producers (Uchi Gold Mine).
  • Shearing and alteration extends 1-2 m from the vein contact; felsic metavocanic (dacite) are sheared and strongly sericitized and mafic metavolcanics (basalt) are sheared and carbonatized.

McVicar Lake Project (Au)

 
 
The McVicar Lake Property is located in the Patricia Mining Division approximately 370 km north-northwest of Thunder Bay, 150 km east of Red Lake and 80 km west of Pickle Lake, Ontario.
  • The Bear Head Fault Zone is a significant crustal scale structure that has localized gold mineralization in the McVicar Lake Property and extends southeast 30 km where it is closely associated with the Golden Patricia Mine (past producer).
  • The Golden Patricia mine contained 0.87 million tonnes grading 19.9 g/t Au (0.58 oz/T Au, and is in a similar structural setting as the lower McVicar Lake area (Chellow Vein). The shear-hosted quartz vein deposit model would be applicable.
  • Surface channel sampling of the Chellow Vein indicated high grade gold values in the western trenches resulting in weighted average grades (uncut) of 85.61 g/t Au over 30 metre length (Trench 1), and 85.82 g/t Au over 10 metre length (Trench 2). (an approximate 1 m sample width is estimated).
  • Five drill holes intersected the Chellow Vein up to a depth of 150 m, and contained anomalous gold values; the vein is primarily shear-hosted and does not increase from the average width of 20 cm.
  • The lack of gold mineralization in drill holes was considered to be likely due to the nugget effect commonly encountered in quartz vein hosted deposits (Waldie, 1993); thin wall BQ drill holes were used.
  • There is excellent continuity of the Chellow Vein and structure along strike and down- dip. Within the immediate area of the Chellow Vein are altered shear zones contain quartz with significant gold values on surface. The the pinch and swell nature of the quartz vein may indicate a plunging system.

 

Angela Lake Gold Project
 
Argo Gold acquired nine claim units totaling 1.7 square kilometres near Angela Lake at the north end of the Birch Uchi greenstone belt in the Red Lake Mining Division in the Spring of 2018. Very localized gold in basal till was discovered in the 1970’s in an area with very little outcrop. Further exploration in the 1980’s resulted in the discovery of boulders with visible gold, to 0.5 cm diameter on a cut surface, hosted within thin quartz veinlets in a metasedimentary host rock. Initial drilling in the 1980’s encountered 0.3 metres of 3.7 g/t, and confirmed that the metasedimentary host rock encountered in drilling was identical to the boulders hosting the high-grade mineralization. Argo Gold believes follow-up exploration activity is warranted at the Angela Lake Gold Project to better define the structure, geology and mineralization. Initial field work is planned for the upcoming field season.
