Access Description: The Madsen gold project is accessible from Red Lake via Highway 618, a paved secondary road maintained year round by the Ministry of Transportation of Ontario (MTO). The Madsen mine site is 10 kilometres southwest of Red Lake. A series of intermittently maintained logging roads and winter trails branching from Highway 618 provide further access to other portions of the property.

Dec 07, 2005 (K R Kettles) - The rocks in the area of Madsen Mines can be grouped into two sequences: a lower tholeiitic to komatiitic sequence and an upper calc-alkalic sequence. The tholeiitic-komatiitic sequence contains two parts as well: a lower part composed of tholeiitic pillowed basalt, which contains the Austin Shear Zone, the host for the gold deposits; and an upper part of tholeiitic-komatiitic felsic to intermediate volcanics with minor interspersed mafic volcanics. Gabbro sills and dikes are present throughout the tholeiitic-komatiitic sequence. The calc-alkalic sequence is composed of rhyolitic flows, tuffs, and breccias. The rocks vary in strike across the area. Near the Madsen Mine the strike of the rocks is 030 deg and the dip is 65 deg to the southeast. One kilometre NE of Madsen the strike is 45 deg dipping 70 deg southeast. Foliation generally strikes 45 to 60 deg and dips 70 deg southeast. The rocks are metamorphosed to amphibolite facies, and are deformed by the shearing. The Ore zones at the Madsen Mine are situated in the Austin Shear Zone, and comprise several en echelon orebodies consisting of lenses of sheared sulphide-bearing metavolcanic flows. Ore zones are parallel to the bedding and oblique to foliation. Individual ore bodies within ore zones are oblique to bedding and parallel to foliation.

Dec 07, 2005 (K R Kettles) - The host rocks for the Madsen ore zones are altered and deformed tholeiitic pillowed mafic metavolcanics. These rocks contain the Austin Shear zone which hosts the gold deposits in the area. They are overlain by tholeiitic felsic to intermediate volcanic rocks previously thought to be part of the upper calc-alkalic sequence. The tholeiitic -komatiitic mafic volcanics are cut by gabbro sills and dikes. In the vicinity of the Madsen mine, the metavolcanics have been depleted in Na2O, MgO, and CaO and enriched in SiO2, K2O, Sb, Li, B, Ba, Ag, S, Zn, Cu, Hg, and Au.

Mar 19, 2012 (K R Kettles) - The Ore zones at the Madsen Mine comprise several en echelon orebodies consisting of lenses of sheared sulphide-bearing metavolcanic flows. Ore zones are parallel to the bedding and oblique to foliation. Individual ore bodies within ore zones are oblique to bedding and parallel to foliation. The ore zones contain variable amounts of pyrite, pyrrhotite, arsenopyrite, chalcopyrite, sphalerite, magnetite, and gold. Scheelite and molybdenite are rare. Finely disseminated pyrite is the most abundant sulphide mineral (Horwood 1940). Most of the gold occurs in the native state as minute inclusions in silicate minerals. Average grade of ore that was produced was 0.292 opt Au and 0.05 opt Ag. 2011: Some results include:15.70 grams Au per tonne over 2.00 metres in MUG-11-13 - McVeigh Tuff, 6.27 grams Au per tonne over 2.00 metres in MUG-11-14 - McVeigh Tuff, 8.06 grams Au per tonne over 2.02 metres in MUG-11-14b - 8 Zone, 5.69 grams Au per tonne over 2.14 metres in MUG-11-16 - 8 Zone, 53.70 grams Au per tonne over 0.70 metres in MUG-11-17 - McVeigh Tuff, 5.64 grams Au per tonne over 2.00 metres in MUG-11-17 - McVeigh Tuff.

May 01, 2015 (Therese Pettigrew) - The South Austin and Austin zones are interpreted as hydrothermally altered fragmental rocks that mark the unconformity between the Balmer and Confederation assemblages. They are a composite unit of hydrothermally altered and heterogeneously deformed mafic volcaniclastic, epiclastic wacke and conglomerate, and local mafic volcanic rock. The McVeigh zone, on the other hand, is described as hydrothermally altered and heterogeneously deformed massive and pillowed basalt (Dubé et al, 2000). All three zones strike on average at 030 degrees and dip between 60 and 70 degrees to the southeast. The Austin zone modelled as part of the present study has a strike length of approximately 3,150 metres, a depth extent of 1,700 metres with a thickness varying from five to over 120 metres. The Austin zone is open along strike and has been observed in the Starratt-Olsen mine area. The South Austin zone was modelled over a strike length of 2,400 metres and extends 1,300 metres down dip. Its thickness varies from five to 70 metres. The South Austin zone is closed along strike to the northeast but remains open to the southwest beyond drilling data. The McVeigh zone was modelled over a strike length of 2,600 metres, a depth extent of 1,750 metres. It varies between five and 80 metres in thickness. The McVeigh tuff is open along strike. According to ACA Howe (1999), the Austin and McVeigh Zones have been traced at surface over at least 4,500 metres. Dubé et al. (2000) describe the hydrothermal alteration associated with gold mineralization in the auriferous zones as consisting of an outer, non-mineralized to anomalously gold mineralized, aluminous assemblage containing andalusite, garnet, biotite, staurolite and amphibole and an inner zone characterized by potassic, metasomatic layering producing a banded texture. The gold is most typically found within the inner potassic alteration zone in its native state as micrometre-sized inclusions in silicate minerals, and also as coatings on sulphide minerals (Ferguson, 1965). The metallic signature is characterized by high gold, silver, and arsenic with minor zinc, antimony, copper and mercury values. Dubé et al. (2000) concluded that the Madsen deposit is not a typical greenstone gold deposit, but rather an ‘early’ manto-style replacement mineralization which was deformed by D2 and metamorphosed by the Killala-Baird batholith. Dubé et al. (2000) also interpret that the strain within the gold zones was relatively moderate with no indications of a regional scale major shear zone or mylonite related to D2 suggesting that the so called “tuffs” are lithotectonic units within the Balmer assemblage. Conversely, from surface and underground observations SRK sees evidence of strong mylonitization, foliation development, strongly contorted overprinting styles of folding, and strain gradients suggesting that the so called “tuffs” units represent deformation zones. In addition, the Austin and McVeigh zones are discordant to Balmer assemblage stratigraphy along strike (the gold zones occur at a high angle to the large F1 fold in the footwall of the Madsen deposit) further suggesting that they do not represent stratigraphic horizons within the Balmer assemblage. The fourth auriferous zone (Zone 8) is hosted in quartz-carbonate veins with common visible gold located close to the contact between ultramafic and mafic units of the Balmer assemblage. The known extent and mining of Zone 8 was originally limited to levels 22 to 27, or approximately 1,061 to 1,321 metres below surface. Further drilling from Claude has expanded the known extent of the Zone 8 vein down-dip. The new Zone 8 model used in resource estimation strikes 030º dips 40º to the southeast and is 100 metres wide and 500 metres deep. Mineralization in Zone 8 is slightly discordant to the other three gold mineralized zones at Madsen.
Apr 30, 2019 (Samuel Lewis) - In 2018, test mining of 7,096 t of mineralized material from 3 stoping areas retuned an average grade of 10.2 g/t Au with an overall mining width of 5.3 m (Pure Gold Nov 28, 2018 press release).
Dec 07, 2005 (K R Kettles) - A depletion of Na2O, CaO, and MgO in the ore zones is indicated by the presence of andalusite, cordierite, stauroliet, almandine garnet, biotite, and muscovite. Potassic metasomatism is indicated mineralogically by the presence of abundant biotite and muscovite (Durocher, 1983). The alteration affects the pillowed mafic metavolcanic flows.
