¹ 2015 MABILO MINERAL RESOURCE ESTIMATE
– Reporting at 0.3 g/t Au lower cut-off.
– The Mineral Resource was estimated within constraining wireframe solids based on the mineralized geological units. Differences may occur due to rounding.
– Prepared by CSA Global.
– Note: Differences may occur due to rounding. All elements reported as total estimated in‐situ for blocks above 0.3 g/t Au lower cut‐off, no recovery factors have been considered. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
– Au equivalent is calculated using the following formula, which incorporates recovery factors from metallurgical test work: Au Equivalent = (75.2%*Au Oz)*$1,200)+((92.8%Cu Tonnes)*$5,200)+((88.4%*Fe Tonnes)*$65)+((60%*Ag Oz)*$16))/$1,200

² Gold Equivalent calculations at US$1200/oz Au and calculated before recoveries

³ Copper Equivalent calculations at US$5000/t Cu and calculated before recoveries

⁴ 2016 MABILO FEASIBILITY STUDY
– The FS is based on a treatment rate of 1Mtpa. A treatment rate of 1.35Mtpa was also considered in an upside case. Factored indicative capital and operating cost estimates were developed for a planned throughput of 1.35 Mtpa, which is presented here as the more likely production scenario.
– All economics, including calculations of equivalent estimates referred in reference to the 2016 Mabilo Feasibility are based on the following commodity price assumptions: US$5000/t Cu, US$1200/oz Au and US$50/t 62% Fe.
– All $ amounts are in $US
– Copper equivalent tonnes produced is based on the following formula – CuEq = (Cu produced/contained*$5000) + (Au produced/contained*$1200+ (Any Contained Fe metal produced* $50))/$5000
– Au Equivalent produced = (75.2%*Au Oz)*$1,200)+((92.8%Cu Tonnes)*$5,200)+((88.4%*Fe Tonnes)*$65)+((60%*Ag Oz)*$16))/$1,200

⁵  NEAR SURFACE OXIDE RESOURCE
– Contained within the 2015 Mabilo Mineral Resource Estimate
– Reporting at 0.3 g/t Au lower cut-off
– The Mineral Resource was estimated within constraining wireframe solids based on the mineralized geological units. Differences may occur due to rounding.
– Prepared by CSA Global

⁶ 2016 MABILO MINERAL RESERVE
– The copper equivalent grade is based on the following formula – CuEq=((((AuOz*$1,200)+(CuMetal*$5,000)+(FeMetal*$50)+ (AgOz*$14)) / $5,000)/Total ore tonnes)
– The 2016 Mabilo Reserve is a subset of the Mineral Resource Estimate.

CAUTIONARY NOTE REGARDING FORWARD LOOKING STATEMENTS
This website includes certain “forward‐looking statements” within the meaning of Canadian securities legislation. Statement regarding interpretation of exploration results, plans for further exploration and accuracy of mineral resource and mineral reserve estimates and related assumptions and inherent operating risks, are forward‐looking statements. Forward‐ looking statements involve various risks and uncertainties and are based on certain factors and assumptions. There can be no assurance that such statements will prove to be accurate, and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially from RTG’s expectations include uncertainties related to fluctuations in gold and other commodity prices and currency exchange rates; uncertainties relating to interpretation of drill results and the geology, continuity and grade of mineral deposits; uncertainty of estimates of capital and operating costs, recovery rates, production estimates and estimated economic return; the need for cooperation of government agencies in the development of RTG’s mineral projects; the need to obtain additional financing to develop RTG’s mineral projects; the possibility of delay in development programs or in construction projects and uncertainty of meeting anticipated program milestones for RTG’s mineral projects and other risks and uncertainties disclosed under the heading “Risk Factors” in RTG’s Annual Information Form for the year ended 31 December 2015 filed with the Canadian securities regulatory authorities on the SEDAR website at sedar.com.
