INTERNATIONAL ARBITRATION COMPLETE

Major Victory for Mt. Labo Against Former JV Partner

RTG’s associate company in the Philippines, Mt. Labo Exploration & Development Corporation, terminated its joint venture agreement with Galeo Equipment Corporation in 2016.

On August 21, 2020, the Tribunal found in favor of Mt. Labo in the Singapore International Arbitration Centre. It was confirmed, that the joint venture agreement between Mt. Labo & Galeo was validly terminated and Mt. Labo’s interest in the Mabilo Project increases to 100% at no cost to Mt. Labo.

  • Mt. Labo was awarded A$33.6 Million in damages & costs
  • Galeo must transfer any surface rights acquired at cost
  • Galeo must deliver originals of all permits and other documents to Mt. Labo
  • Galeo was and is not entitled to be named authorized operator or exclusive driller at Mabilo
  • The Tribunal dismissed all of Galeo’s counterclaims

2016 Mabilo Feasibility

The feasibility study demonstrates a robust and financially viable new development opportunity even at low commodity prices. Strong gross margin provides very high sensitivity to both commodity prices and new tonnage from expected resource growth. Feasibility economics are based on $1200/oz Au & $5200/t Cu and on 100% basis, the numbers presented here have been updated as of 21 August 2020: US$2.96/ lb Cu, $1,942/oz Au, 62% Fe US$122.79. All amounts are expressed in $US.

Early cash flows at incredibly low cost

  • Oxide mining operation in first 18 months
  • Low startup capital with early access to high grade shallow gold cap ore
  • Generates cashflow within 4-5 months of DSO permitting
  • Close to paved roads, grid power, water
  • Local established plant available to process oxide gold cap
  • 100,000t at 23% Cu in the ground
  • DSO skarn & chalcocite material through port ~40km from Mabilo

Mabilo Project Footnotes

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

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

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

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

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

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.
