Slide 3: Outline
Outline For personal use only • Gold discovery in the NW Gawler Craton • Marmota’s regional gold exploration program • Gold deposit at Aurora Tank • Future milestones SAEMC CONFERENCE DECEMBER 2017 3
Slide 4: Gold discovery in the NW Gawler Craton
Gold discovery in the NW Gawler Craton For personal use only • Archean rocks of NW Gawler Craton highly prospective for gold. • ‘Old timers’ found a few deposits such as Earea Dam & Malbooma by prospecting. • No drainage or exposure over most of Craton so prospecting is generally ineffective. • Reco
Slide 5: Marmota's Gawler Craton gold tenements
Marmota’s Gawler Craton gold tenements For personal use only 350,000m E 400,000m E 450,000m E Aurora Tank Marmota’s tenements in the Gawler Craton around the Challenger Gold Mine • Total area 6,000km2. 6,700,000m N LC • Centred on the Challenger Gold Mine. Challenger • Large coverage of prospective
Slide 6: Marmota's gold exploration strategy
Marmota’s gold exploration strategy For personal use only • Seeking the next Challenger – or something new – with higher ounces per vertical metre. • Challenger (right) has produced over 1 million ounces of high-grade profitable gold. • Marmota has highly prospective tenement holding of 6,000 km2 ar
Slide 7: Challenger gold discovery geochemistry
Challenger gold discovery geochemistry For personal use only • October 1994 1.6km spaced sampling gave 180ppb gold anomaly with 3-7ppb halo. • Infill located a major anomaly peaking at 620ppb. • Drilling confirmed Challenger discovery in May 1995. • If original sample was 200m away it would have ass
Slide 8: Calcrete sampling – thickness of cover

Slide 9: Previous regional calcrete sampling
Previous regional calcrete sampling For personal use only • Mines Department data show most of Marmota’s tenements have only been sampled at 1.6 or 1.0 km spacing. • This can miss significant anomalies. • Closer spaced sampling to at least 400m is planned to locate new mineralisation under shallow c

Slide 11: Aurora Tank history
Aurora Tank history For personal use only • Aurora Tank has been known as a gold prospect since it was discovered by calcrete sampling in 1997. • Intermittent historical exploration consisted of calcrete sampling between 1997 and 2013 and drilling between 1999 and 2015. • Historical drill holes were
Slide 12: Aurora Tank September 2016
Aurora Tank September 2016 For personal use only • Aurora Tank calcrete anomaly peaks at 59ppb Au. • Best historical result 4m at 5.0g/t Au from 16m in hole 14AT003. • September 2016 program of 98 holes on a 40 x 80m pattern outlined the best secondary dispersion gold anomalism. • Marmota September

Slide 15: Recent diamond drill holes location
Recent diamond drill holes location For personal use only • In November 2017 a 6-hole diamond drilling program for 206 metres of core was completed. Assays are awaited. • New geological insights: −− an intermediate dip of schistosity of 30–40 degrees to the northwest. −− an overlying unit of Algebuc
