HELM’S DEEP
Basalts
Felsic volcanics
Sandstones, wackes, conglomerates
1.12 g/t Au, 2.12% Cu, 23.5 g/t Ag
2.82 g/t Au. Sheared wacke with Tr Py.
0.68 g/t Au. Qtz-Tourmaline vein
Eastmain-1 Reservoir
Eastmain-1 Reservoir
➢ Several new gold showings found in 2017-2018 → Quartz veins with strong, proximal biotite-tourmaline alteration, and distal calcsilicate alteration, in sandstones.
➢ No previous recorded exploration on most of the project
➢ The new, 10 years old Eastmain-1 hydro reservoir provides lots of new, very high quality outcrops; most of the shoreline has never been prospected (by Midland or others)

Very abundant Calc-Silicate alteration in sandstones. Also lots of Quartz-Biotite-Tourmaline veins (Amazing rocks!)

Helm’s Deep - Polymictic Conglomerate with Tourmaline Alteration in Matrix

Similar polymictic conglomerates are found near Eleonore and could mark the location of a major normal fault reactivated during further compression (Timiskaming-type)

Helm’s Deep Project: Highlights
➢ Features several new orogenic gold showings hosted in sandstones and Timiskaming-type polygenic conglomerates of the Auclair formation
➢ Located on the shores of the new Eastmain-1 hydroelectric reservoir. New very high-quality outcrops were created by the flooding. Only a small part of the reservoir shorehas ever been prospected.
➢ Three new gold showings found in 2017-2018: 2.82 g/t Au, 0.72 g/t Au, 0.68 g/t Au,0.73 g/t Au / 0.5m (channel). Gold mineralization occurs as quartz veins and veinletswith strong, proximal biotite-tourmaline alteration, and distal calcsilicate alteration, insandstones.
➢ Abundant and widespread veining and alteration in the sandstones and polygenicconglomerates (biotite, tourmaline, diopside, actinolite alteraitons)
➢ Alteration, host rocks very similar to the multi-million ounces Eleonore gold deposit(Goldcorp). Near significant Au discoveries on the Clearwater Au project
