Exploration History

1939: A.D. Williams did trenching on a showing to the southeast of Dans Lake. Surface sample assays up to 0.024 ounce gold per ton were reported. 1968-69: W.G. Wahl did ground geophysical surveys over the area. 1973: Northex Management carried out mapping and sampling. 1983: Canadex Resources Limited and associated companies conducted a mapping and sampling program on the property. 1984: Canadex carried out trenching.

Geology Comments

Dec 07, 2005 (R TUOMI) - The area surrounding the occurrence is underlain by an east trending sequence of massive to pillowed metabasalt and felsic metavolcanics, mainly lithic and crystal tuff. Several outcrops of clastic sediments are interfingered with mafic metabasalt. The sequence is intruded by gabbro and small quartz porphyry intrusives. The largest of these porphyry intrusives is mineralised by fine grained pyrite at its southern contact and this area was trenched by A. D. Williams in 1939.

Lithology

Lithology Comments

Dec 07, 2005 (R TUOMI) - MINERALIZATION OCCURS IN: contact between porphyry and mafic basalt HOST ROCK: porphyry and mafic basalt OTHER ASSOCIATED ROCK TYPES: 1) clastic metasediments, 2) gabbro.

Feb 13, 2020 (Therese Pettigrew) - South of Dan's Lake a second intrusive, a pink equigranular to porphyritic syenite body (Williams porphyry), is found at the contact between the volcanic cycles. Strongly carbonatized felsic pyroclastics are found to the north of this intrusive (underlying it) and mafic flow and intercalated tuff and chert overlie it (Assessment report 52G15NW0019).

Mineralization

Mineralization Comments

Feb 13, 2020 (Therese Pettigrew) - In 1939, A. Williams submitted sketches of trenching and assays on an 8-claim block. The sketch shows extensive trenching along a syenite/greenstone contact. Marginal notes refer to heavy mineralization in all trenches and state "well mineralized body probably 50 to 60 feet wide and trenched for approximately 1000 feet. Assays made at St. Anthony Mine.” The following assays (grab samples?) are shown: 0.04 opt Au, 0.21 to 2.36 opt Au, 1.6 opt Au, 0.35 opt Au, 0.14 opt Au, and 0.18 opt Au. Mapping and drilling in 1973 revealed a pyritic-carbonate felsic tuff cut by quartz-carbonate veining which returned 0.055 oz. gold per ton over 9 feet in one of two short holes (Assessment report 52G15NW0019).

Alteration Comments
