VANCOUVER, British Columbia, Feb. 27, 2019 (GLOBE NEWSWIRE) -- Pure Gold Mining Inc. (PGM – TSX-V) (“Pure Gold” or the
“Company”) is pleased to announce results of a Preliminary Economic Assessment (“PEA”) for its Fork, Russet South, and Wedge
deposits that demonstrate the potential to add approximately $51 million to the Madsen Gold Project (“Madsen”) after-tax net
present value. As a result of high gold grades, near surface resources, and use of existing infrastructure, mining of these
zones will yield an after-tax IRR of 39%.
The results of this PEA highlight the tremendous prospective upside at Madsen-Red Lake, the economic viability
of Madsen, and demonstrates how Pure Gold would phase new discoveries into future mine plans. Based on the current resource,
development of these new discoveries could add approximately four years of production at below-industry average cash costs while
generating robust cash flows.
“Our PEA provides us with a blueprint of how we could expand our mine life and production profile at Madsen, and
illustrates just how impactful and accretive new discoveries can be to the future of our district,” stated Darin Labrenz, President
and CEO of Pure Gold. “We have deployed a modest amount of capital in discovering and delineating these new resources and the
return on our investment is exceptional. This PEA, represents the first conceptual expansion scenario for the future phased
growth of the Madsen Mine complex.”
PRELIMINARY ECONOMIC ASSESSMENT HIGHLIGHTS
Base case parameters assume a gold price of US$1,275/oz and an exchange rate (C$ to US$) of 0.75.
All currencies reported in Canadian dollars unless otherwise specified.
- Mine life extension of 3.7 years with total production of 210,000 ounces of gold;
- Life of mine (“LOM”) direct operating cash cost(1) estimated at US$557 per ounce of payable gold;
- LOM all in sustaining cash cost (“AISC”) estimated at US$712 per ounce of payable gold;
- Pre-tax NPV5% and IRR of $79 million and 57% respectively with a 1.6 year payback of initial capital; and
- After-tax NPV5% and IRR of $51 million and 39% respectively with a 2.0 year payback of initial capital;
- Initial capital requirement of $57 million including a 14% contingency.
(1) Cash cost includes mining cost, mine-level G&A, mill and refining cost. This is a non-GAAP
performance measure; please see “Non-GAAP Measures and Other Financial Measures” below.2
The PEA is preliminary in nature and includes inferred mineral resources that are too speculative
geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is
no certainty that PEA results will be realized. Mineral resources are not mineral reserves and do not have demonstrated economic
viability.
OVERVIEW
The PEA evaluated a range of mine plans from 400 tonnes per day (“tpd”) to 800 tpd, and considered ramping up
throughput to concurrently process the material from the PEA with the Madsen reserve. However, unless the Inferred Resources
from Russet South, Fork and Wedge are converted to Indicated, the only scenario the PEA could contemplate is to conceptually mine
the three deposits after the end of the feasibility mine plan. Pure Gold intends to continue work to upgrade and expand
mineral resources so that further mine plan optimizations may be advanced.
Each of the PEA deposits will be mined from underground, with separate portal and ramp systems established to
access the mineral resources in the mine plan. The PEA mine plan relies on the surface and milling infrastructure described in the
Madsen Feasibility Study. Mining will be conducted concurrently from Russet South, Fork and Wedge to support a milling rate of 800
tpd. At Russet South, only the shallow portion of the mineral resource was considered to fit for the 800 tpd base case,
excluding approximately 52,400 potential ounces from the base case plan.
The PEA implementation schedule spans a period of 12 months, with portal construction and underground mine
development at the three deposits commencing approximately 12 months before the first gold pour. The project requires initial
capital of C$57 million (including contingency) to support the construction of the underground mines and associated infrastructure.
The mine plan is expected to produce 210,000 ounces over LOM with all in sustaining costs of US$712/oz gold, which are below
industry averages.
JDS Energy and Mining Inc. led the PEA, which included contributions from industry-leading consultants such as
Knight Piésold Ltd., Lorax Environmental Services Ltd, Ginto Consulting Inc., and Equity Exploration Consultants Ltd.

- Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty
that all or any part of the Mineral Resources estimated will be converted into Mineral Reserves. The estimate of Mineral
Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other
relevant issues. The CIM definitions were followed for the classification of Indicated and Inferred Mineral Resources. The
quantity and grade of reported Inferred Mineral Resources in this estimation are uncertain in nature and there has been
insufficient exploration to define these Inferred Mineral Resources as an Indicated Mineral Resource and it is uncertain if
further exploration will result in upgrading them to an Indicated Mineral Resource category. All figures have been rounded to
reflect the relative precision of the estimates. Mineral Resources are reported at a cut-off grade of 4.0 g/t gold.
Mining
Multiple scenarios from 400 to 800 tpd were completed to evaluate and schedule the mineral resources of the PEA into a
mine plan. A 400 tpd scenario considered ramping up throughput to concurrently process material from the feasibility mine
plan, Fork, Russet South, and Wedge, however the PEA considers Inferred Resources and unless they are converted to Indicated and
until future study work is completed, any potential processing must occur after the end of the feasibility study mine plan.
As such the 800 tpd scenario was selected as the base case mine plan as it optimizes the Madsen Feasibility Study design plant
capacity.
Deeper portions of Russet South included in the 400 tpd case were not considered in the 800 tpd case, due to the
timing to develop this area. A total of 52,437 ounces (196,289 tonnes grading 8.31 g/t gold) was excluded from the 800 tpd
mine plan. Ramp access was selected due to the near surface nature of these deposits. The PEA mine plan utilizes a
combination of development on mineralization (17%), mechanized cut & fill (15%), and longhole mining (68%) methods to extract
mineral resources. Mineral Resources forming the selected base case 800 tpd schedule are comprised of 58% Indicated and 42%
Inferred and are sourced from Wedge (50%), Fork (34%), and Russet South (16%). Both the 400 tpd case and the selected base
case 800 tpd mine plan are shown below.

Processing
The PEA will utilize the same flow sheet developed for the Madsen Feasibility Study, and will accommodate
additional tailings with lifts of 2 to 4 metres to the polishing pond dams. Overall metallurgical recoveries for the mine
plan are expected to be 96%, based on new test work conducted on recent drill core from the Russet South, Fork and Wedge
deposits.
Capital Costs
Total pre-production capital cost (capex) is estimated at $57 million (US$42.9 million), inclusive of a $7.1 million
contingency. The total life of mine capex is $101 million (US$76 million), inclusive of incremental closure costs.
Underground mining and haulage is anticipated to be completed using an owner-operator development model
operating 365 days per year. LOM sustaining capital costs are estimated at $43 million with the majority of the costs associated
with underground mine development.

Project Enhancement Opportunities
The PEA confirms that Russet South, Fork and Wedge have the potential to be economically viable. While the PEA
is based on a subset of the 206,000 ounces Indicated and 226,000 ounces Inferred at Russet South, Fork and Wedge, Pure Gold’s
exploration success to date demonstrates potential to add additional resources in each of these areas. Additionally, if
existing resources were upgraded to indicated, it would allow the Company to study an opportunity for concurrent mining through an
increase in throughput, though there is no certainty that resources will be upgraded to indicated or converted into reserves.
Specific opportunities include:
- Exploration drilling with the goal of converting inferred resources to indicated and expanding the mineral resource
including;
- Expansion of the mineral resource at Russet South, where drilling in 2018 expanded the resource to a vertical depth of
330 metres below surface, including 19.0 g/t gold over 2.0 metres from drill hole PG18-504 and 35.9 g/t gold over 1.0 metre
from drill hole PG18-537;1
- Continued exploration and growth at Wedge, where strongly mineralized zones have been intersected at a vertical depth of
500 metres, and where recent results include 32.9 g/t gold over 1.7 metres from PG18-600 and 23.1 g/t gold over 2.0 metres
from PG18-616; 2
- Evaluation of concurrent mining with an opportunity to improve the production profile at Madsen and to allow for
opportunities to mine the deeper resource at Russet South where 196,289 tonnes at a grade of 8.3 g/t gold was excluded from the
800 tpd mine plan.
