The PEA report will be posted to SEDAR May 2nd, 2018.

Geoff Hampson, Para’s CEO states, “We are very pleased with the results of the Gold Road PEA and the validation of the investment thesis we developed when we acquired it. The PEA quantifies the robust returns and strong cash-flow for this project. The NPV of this project when compared to the current market capitalization of the whole company indicates that our shareholders will be rewarded for their patience and belief in our business plan. In addition, we consider the analysis by RPM as a base case and have already developed strategies to quickly ramp up production in 2019 to 500 TPD, increase the head-grade by developing working faces in historically higher-grade rock and to take advantage of the currently higher price of gold than was used in the study.”
Ian Harris, Para’s President states, “The PEA provides the green-light to move forward with a quick restart of the Gold Road Mine. Our near-term focus will be on finalizing our startup plan, mine contract bidding, and executing an exploration plan intended to increase the resources at Gold Road and seek higher-grade material along the TrUe Vein. We plan to re-start operations at Gold Road in September of 2018 and expect to achieve full production by mid-2019. The PEA reports that the mill and mine infrastructure is in excellent shape and requires very little in the way of capex. The only major capex is required to install a shaft and headframe to reduce the cost of extracting material from the mine. We can produce using 20-tonne underground haul trucks up the 2-mile-long decline while the shaft is under construction.”
The PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the results included in the PEA will be realized. If the Company were to bring the Gold Road mine into production without first establishing mineral reserves supported by a feasibility study, the Company cautions that this could result in higher risk of economic or technical failure of the operation than if a feasibility study had been prepared demonstrating economic and technical viability. There are no assurances that the Gold Road mine will be found to be economic.
Mineral Resource Estimate
Resources were supported by 14,768 channel samples. The database contains 19,400 assay data excluding the 16 drill holes which were not used in the resource estimate. The channel samples were taken within the mined stopes and the development workings. Channels are spaced every five feet along the drifts.
All the Inferred mineral resources are reported using a 0.1 ounces per ton (opT) Au cutoff, which is roughly the current economic cutoff. In order to meet the international requirement of reasonable prospect for eventual economic extraction, the mineral resources quoted in this report are constrained within a maximum vertical distance of 200 ft from a drift.

The underground mine historically used Shrinkage Stoping Mining (SSM). During the most recent mining phase, haulage of the mineralized material and waste to the surface was with underground trucks. RPM Global reviewed the continued use of SSM for the Gold Road Mine and has also reviewed an alternative mining method known as Raise Access Mining. Raise Access Mining (RAM) incorporates an Alimak style raise climber to develop the access raise in materialized material from the sill level to the top level. Once the raise is established, the climber is used to drill and blast horizontal production holes from the bottom of the mineralized block up in retreat. The mineralized material is loaded from the bottom sill level using a mucker loading into nearby muck bay, a truck for the haul up the decline or to the proposed new shaft loadout. Gold Road used a form of RAM in a test stope in the past with mixed results. RPM advises that the use of RAM is the preferred method and has been used in the PEA as part of the restart. RAM provides a safer mining process, with limited, to no exposure of the miners to unsupported ground, as well as lower operating cost. Both mining methods are discussed in the PEA.
RPM also reviewed alternative haulage methods using the current truck haulage decline (11,000 ft. one way) as well as a truck/shaft haulage scenario. As expected the truck/shaft method was the preferred alternative due to costs and efficiency.
Metallurgical Test work and Mineral Processing
The processing parameters for Gold Road mineralized material have long been established by both actual processing over many years and by metallurgical test work. The gold is present as very fine particles in extremely hard, chalcedonic quartz. Processing requires grinding to 80% passing 325 mesh and 24-hour leaching which results in about 95% gold extraction.
Excluding the processing in the early-1900s, about one million tons of Gold Road mineralized material grading about 0.2 ounces gold/ton have been processed by the following two plants:
- A 400-ton/day counter-current-decantation/Merrill-Crowe plant, operated from 1937 to 1941
- A 500-ton/day carbon-in-pulp (CIP) plant, operated from 1996 to 2016
The latter plant is still in existence and is in good condition. Tailings from the current plant are filtered and dry- stacked in a tailings storage facility (“TSF”) close to the plant.
Capital and Operating Costs
The total capital costs for the restart of the Gold Road Mine include US$5.2M for the restart, preliminary development and shaft / hoist installation and purchase of the raise climbers completed in year 1. All other development and other capital cost are considered to be sustaining capital for the remaining LOM.
Estimated capital cost to bring the processing plant into operational condition is US$0.5 million. No capital costs are anticipated for the infrastructure.
The underground mine operating costs were developed on a per-foot of advance basis for the waste development. Other operating costs includes raise mining (in mineralized material), production mining, contractor labor and management and Gold Road site management for the underground mine. Total mining costs are US$66 per ton.
Estimated processing operating costs are US$27/ton. Estimated G&A costs are US$15/ton of mineralized material processed or about US$2.5 million/year.
The total capital costs for the restart of the Gold Road Mine include US$5.2 M for the restart, preliminary development and shaft / hoist installation and purchase of the raise climbers completed in Year 1 and 2. All other development and other capital, is considered to be sustaining capital for the remaining LOM. The table below shows the economic assumptions and results.
