A 1.2 km road connects the exploration area to Mari Lake.
Geology and Mineralization
The Mari Lake Project is situated at the geological contact between the Kipahigan granodiorite and the Kisseynew gneisses in the Kisseynew Domain. The mineralized zone, which strikes northwest and dips 45°NE consists of a series of white, glassy massive gold bearing quartz veins with associated blebs and disseminations of pyrite, pyrrhotite, chalcopyrite, possible molybdenite and tourmaline
Significant gold concentrations are associated with wide zones of shearing and silicification along the granodiorite margin. Gold mineralization is linked to subtle secondary fracturing and microstructures that crosscut the main structural trend. Folding and boudinage of the quartz veins suggest that the quartz veins were intruded into the shear system as fracture fillings early in the history of the shear zones.

Exploration
Gold was discovered in the Eccles (Mari) Lake area in the 1930s, with significant exploration between 1945 and 1986. There is no record of exploration after 1986, leaving the project open for modern exploration by Searchlight.
1945
In 1945, Nesnah Mining and Exploration Company Limited completed 15 trenches and 16 diamond drill holes [1, 2]. The trenching exposed gold mineralization over a strike length of 1,075 ft (327.7 m). The most significant results were in Trench 11 with assays of 1.28 oz/ton (43.89 g/t) Au over 10 ft (3.05 m), and 0.70 oz/ton (24.0 g/t) Au over 3.0 feet (0.91m).
Visible gold was reported in trenches 3 and 10. (Table 1)
The 16 shallow drill holes totaled 1,709 feet (520.8 m). Visible gold was reported in two drill intersections, with corresponding assays of 0.85 oz/ton (29.14 g/t) Au over 2.8 ft (0.85 m), and 0.52 oz/ton (17.83 g/t) Au over 2.5 ft (0.76 m) (Table 1). Drill Hole ML 14 shows two zones of gold mineralization. (Table 2)

1965
In 1965, a total of 10 pits were completed, with results which included 2.98 oz/ton Au, and 1.41 oz/ton Au [3]. A quartz vein 7.8 ft by 440 ft (2.37 m by 134.2 m) was exposed as part of a stripped outcrop measuring 980 ft by164 ft (298.7 m by 49.98 m). (Table3)
