Dorothy and Dobie Deposit

The Dorothy and Dobie Gold Deposits are just two of the multiple deposit-scale targets and Gold Prospects identified within Ardiden’s Eastern Hub of its district scale Pickle Lake Gold Project, encompassing >100km of under-explored strike.

The Kasagiminnis Deposit is located 40km south-east of the Dorothy Deposit but forms part of the same regional mineralised system.

Previous owners of the two Gold Deposits completed non-JORC estimates at Dorothy and Dobie which combine to an historical estimate of 99,600 oz Au @ 5.7 g/t Au, down to less than 150m below surface (ASX release 2 August 2017):

  • Dorothy Main Deposit: 46,600 oz @ 6.17 g/t Au (Major General Resources, 1990);
  • Dobie Deposit: 53,000 oz @ 5.50 g/t Au (St Joe Corp., Canada, 1987).

The Dorothy-Dobie mineralised zone represents a larger mineralised system than currently defined at Kasagiminnis.

Gold mineralisation at Dorothy, Dobie and Esker occurs along a 20 km long north-westerly trend, along strike from the historical Golden Patricia mine, and includes the Meen, Cooper, West, Dorothy Main, Tonsil, Spike and Dobie Prospect zones. Mineralisation styles and host rocks vary, and are all structurally controlled with two high priority structures defined across the Western Hub.

The Company has conducted a technical study with Southern Geo Science consultants and Leigh Rankin (renowned structural geologist) to identify a structural and lithological model. This geological model has generated targets across the Western Hub that are currently being drilled with 5,939m completed in 2022.
