The Kitsol prospect is located on the west bank of the Kitsault River, 24 kilometres north of Alice Arm. The South Musketeer (103P 019), probably an extension of the Kitsol, lies just across the river on the east bank. The Kitsol prospect was extensively explored by Dolly Varden Mines in the early 1970s.

The area is underlain by a sequence of volcanic and sedimentary rocks of the Upper Triassic Stuhini Group and the Lower-Upper Jurassic Hazelton Group. The sequence is folded into the doubly plunging, north-northwest trending Kitsault River syncline and has been regionally metamorphosed to greenschist facies.

The deposit comprises a stratiform volcanogenic silver-lead-zinc barite exhalite horizon hosted in Hazelton Group andesitic tuffs and breccias that have been variably propylitized, silicified and carbonatized. The horizon strikes north-northeast for 91 metres, dips near vertically, is approximately 5.5 metres wide and has been traced downdip for 107 metres.

The mineralogy of this deposit is similar to that of the Torbrit (103P 191), displaying colliform-banded quartz, calcite, barite and jasper mineralized with pyrite, marcasite, galena, minor sphalerite, minor chalcopyrite and traces of pyrargyrite and native silver.

The deposit averages 340 grams per tonne silver over its 91 metre strike length on the surface (Geology, Exploration and Mining in British Columbia 1973, page 489). A 5.5 metre drillhole intersection 107 metres below the surface outcrop assayed 546.1 grams per tonne silver (Property File - Dolly Varden Mines 1972 Annual Report).

In 1989-90, Dolly Varden Minerals Inc. conducted a comprehensive surface diamond drilling program on portions of the North Star (103P 189), Dolly Varden (103P 188), Torbrit (103P 191) deposits and the V zone (103P 010). Two holes were drilled on the Kilsol No. 1 claim (Lot 3815) totalling 439.5 metres.

During 2010 through 2019, Dolly Silver Corporation explored the area as apart of the Dolly Varden property. A complete property exploration history can be found at the Dolly Varden (MINFILE 103P 188) occurrence.

In 2014, drilling yielded intercepts of up to 712.2 grams per tonne silver over 25.95 metres, including 1496.8 grams per tonne silver over 9.01 metres in hole DV14010 (Higgs, A.A. (2015-05-01): Amended 2015 Technical Report for the Dolly Varden Property).

In 2015, drilling yielded intercepts including 21.6 grams per tonne silver over 7.0 metres in hole DV15018, 60.3 grams per tonne silver over 3.0 metres in hole DV15021 and 99.5 and 16.2 grams per tonne silver over 0.5 and 5.2 metres, respectively, in hole DV15020 (Turner, A.J. (2019-05-08): Technical Report and Mineral Resource Update for the Dolly Varden Property).

In 2018, diamond drilling yielded intercepts including 302.2 and 332.8 grams per tonne silver, 0.26 and 0.45 per cent lead with 0.41 and 0.22 per cent zinc over 31.00 and 22.15 metres (30.38 and 21.81 metres true width) in holes DV18131 and DV18135, respectively (Turner, A.J. (2019-05-08): Technical Report and Mineral Resource Update for the Dolly Varden Property).
