The 2204ha Mari Lake Property is located within the Trans Hudson Corridor in Saskatchewan and is prospective for structurally-controlled mesothermal lode gold mineralization. Acquired in 2020, the property lies 25km NNW of Flin Flon, Manitoba. The property area is accessible via a network of forestry roads that branch from the Hanson Lake Hwy #106 west of Creighton, Saskatchewan, winter access is via ice roads.
The claims cover 2 high grade gold mineral occurrences associated with Kisseynew Group volcanics
- Excellent geology favourable for mesothermal lode gold deposits
- Significantly underexplored with encouraging early results
- Mineralization open in both directions along strike and to depth
- Untested stratigraphic unit containing two high-grade gold occurrences
- Excellent Infrastructure nearby: Provincial Highway 9 km south of property boundary, Hydro
The Mari Lake claims cover Trans Hudson Orogeny group rocks (metavolcanic, plutonic and minor metasedimentary). This stratigraphy is favourable for precious- and base-metal exploration.
Both the Aga Au-As and Naza Au-Cu Showings areas are underlain by the Kisseynew Group, light to dark grey, fine-grained, garnet porphyroblastic garnet-biotite gneiss. These volcanic-derived gneisses are complexly folded. The Cotteral Lake anticline is an open assymetric fold with a highly crenulated crestal zone, plunging 5° to the north.
The Aga Showing was discovered in 1991 while doing follow-up work over a 1990 lake silt gold anomaly. The showing occurs in a band of rusty black, well foliated, weak to well banded mafic rock (amphibolite and hornblende±biotite gneiss) near the northeast-striking contact between this rock and a buff to brown, weakly foliated, garnet porphyroblastic quartz-feldsparbiotite-hornblende gneiss. This unit is a southern extension of the same stratigraphic interval which hosts the Naza Showing. The host outcrop has been contorted by a gentle to open, north-northeast-trending, 015°-plunging fold which is located on the upper west limb of the major anticline (the anticline hinge is located to the east of the showing).
Government geological mapping first occurred in the Mari Lake area between 1949 and 1951. In 1985 the GSC geologically mapped the Naza showing area.
The Naza showing area was first staked in 1961. In 1964, Hudson Bay Exploration and Development completed a ground EM survey which covered the showing area.
In 1989, BHP Minerals Canada Ltd. staked the Naza showing area. Between 1990-92 BHP completed a helicopter-borne EM, VLF, and magnetic survey and a follow-up program which included geological mapping, rock, lake sediment, and humus sampling, and ground-based geophysics. This work resulted in the discovery of the Naza Showing.
BHP then completed geological mapping, prospecting, and rock and humus sampling on the Naza grid resulting in the discovery of the AGA Showing approximately 2 km to the north. The showing occurs within the same stratigraphic unit as the Naza Showing. Elevated gold values occur within this unit between the two showings.
The property has been tested with two diamond drill holes located 1.4km north of the Naza Showing and 1.3km west of the Aga Showing. Neither drill hole tested the target stratigraphy that hosts the gold mineralization.
Taiga Gold Corp. Exploration
Taiga Gold Corp acquired the Mari Lake claim block in Q2 2020 and has not completed any work on the project.
Compilation of all geological data including historical geochemical and geophysical information is underway and will be imported into a GIS database for analyses and interpretation. These results will be used to guide a field program consisting of grid-based geochemical sampling, prospecting, geological mapping and geophysics.
