Kim Evans, Golden Reign President and CEO, states, "Our San Albino Gold Deposit is a low tonnage, high-margin gold project with a robust estimated average mined grade of 8.02 g/t gold equivalent. Our strategy, which is now well advanced to being realized, is to establish a financeable, low cost, profitable cornerstone operation at San Albino - an area that represents only 2% of our landholdings - with the aim of self-funding exploration and growing our operations in a non-diluting manner, through free cash flow. Golden Reign's vision is to replicate the success of the San Albino mine development throughout our highly prospective 138 sqkm land package."
Project Sensitivities
Due to its high-grade nature, the project shows strong resilience to variances in gold prices, thus mitigating risk. The table below shows gold price sensitivities for the range of US$800 to US$1,500 per ounce of gold.

Open-Pit Mining
The PEA production plan contemplates four separate open pits - West Pit (Phases I & II), SW Pit, NE Pit and Central Pit - to be developed and mined over approximately eleven years.
The optimized pit and resulting design has an overall wall slope of 45?, a cut-off grade of 1.46 g/t AuEq for oxide material and 1.40 g/t AuEq for fresh rock, and a life of mine average strip ratio of 5.2:1.

* the dilution grade is estimated to be 1.07 g/t Au and 4.3 g/t Ag applied to all pits, with in-pit dilution tonnage ranging from 27-46% depending on the lens width, and an ore loss factor of 3% for all pits.
Mill Feed Source and Head Grade (Au)
The following chart illustrates the open-pit mill feed supply by year and anticipated head grade. The head grade peaks near the end of the open-pit schedule in years 9 to 11 as the West Pit deepens into the high grade fresh rock mineralization (>12 g/t Au).

Underground Mining
As the gold zones become deeper and open pit strip ratios increase, underground mining methods will be applied. There is a 3-year transition period (years 10 through 12) during which open-pit operations taper off and underground production ramps up. From year 13 onwards, production is solely from underground operations.
The envisioned underground mining operation has a vertical depth of 315 metres, extending 900 metres along strike and 800 metres down dip, comprising 30 potentially mineable blocks - representing the bulk of the mill feed tonnage (67%).

* the dilution grade is estimated to be 0.68 g/t Au and 2.5 g/t Ag on underground dilution of 20% with underground recovery estimated at 76.5% for stopes, and zero dilution and 100% recovery in development drives.
At an average true thickness of 2.6 metres, the deposit has a general dip angle of 25 degrees which does not allow for the use of in-stope trackless equipment. The primary mining method is envisaged to be steep panel mining using jacklegs and slushers.
The highest head grades are expected to be achieved after year 20, when the underground mining operations encounter deeper higher grade zones.

The PEA is a conceptual study of the potential viability of mineral resources. The potential mill feed tonnages utilized in the PEA contain both Indicated and Inferred resources. The reader is cautioned that Inferred Resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that value from such Resources will be realized either in whole or in part. As the Company does not intend to complete a Pre-Feasibility or Feasibility Study prior to potentially commencing small scale production at the San Albino Gold Deposit there is an increased risk that the economic and technical aspects of the PEA may not be realized.
Mineral Resources
P&E has prepared an updated mineral resource estimate for the San Albino Gold Deposit, which has been used as the basis for the PEA and will be included in the NI 43-101 technical report.

Mineral Resource Estimate Notes and Parameters:
1) 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;
2) The mineral resources were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.
3) The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues, although the Company is not aware of any such issues;
4) The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resource category;
5) Metal prices were based on a two year trailing average as of September 30, 2014. The gold price was US$1,404/oz and the silver price was $23.47/oz.
6) Gold Equivalent was calculated on the basis of 1 gram gold = 71 grams silver.
The 2015 mineral resource estimate update categorizes resources as either In-Pit (open-pittable) or Out-of-Pit (underground).

At present, over 40% of the In-Pit resources fall within the Indicated category - 153,600 AuEq ounces averaging 7.28 g/t AuEq.
The updated resource calculation employs a higher cut-off grade (previously 0.23 g/t AuEq cut-off) resulting in 4 separate, smaller open pits.
With additional shallow in-fill drilling and trenching of the inter-lying areas, there is potential to increase open-pittable resources and mine fewer, larger open-pits.
The near-surface San Albino Gold Deposit remains open along strike in both directions and down dip.

Mitigating Risk
Golden Reign continues to actively work to mitigate the risk associated with developing the San Albino Gold Deposit by:
- focusing on a high margin development scenario, with low-tonnage, high-grade material and a modest initial capital investment requirement
- completing substantial, advanced metallurgical test work for the PEA, where simple gravity concentration tests returned excellent gold recoveries and overall recoveries for the oxide zone were 91% for gold, 59% for silver and fresh (sulphide) zone were 95% for gold and 91% for silver
- utilizing existing infrastructure - the project is easily accessible via good year-round roads, it has multiple on-site water sources, the national power grid passes directly through the property, its gentle topography is very amenable to the planned mining operations
- continuing to nurture and develop strong community relations
- maintaining good relationships with the Nicaraguan government and its agencies
- planning the expansion of potential resources through additional shallow drilling and trenching
- securing funding for the development and construction of the San Albino mine under a Gold Streaming Arrangement with Marlin Gold Mining Ltd.
Gold Streaming Arrangement
In July 2014, Golden Reign completed a Gold Streaming Arrangement (the "Arrangement") with Marlin Gold Mining Ltd. ("Marlin") (TSX-V: MLN) at the Company's San Albino Gold Deposit (refer to Company news release dated July 11, 2014). The Arrangement covers solely the San Albino Gold Deposit, a 3.5 square kilometre area within the Company's highly prospective 138 square kilometre landholding
For a purchase price of US$15.0 million Marlin's wholly-owned subsidiary, Sailfish Royalty Corp. ("Sailfish") will be entitled to purchase 40% of gold production from the San Albino Gold Deposit, comprising a total 3.5 square kilometres, at US$700 per troy ounce1 until Sailfish recovers US$19.6 million2. Thereafter, Sailfish will be entitled to purchase 20% of gold production at US$700 per troy ounce3. Prior to commercial production, Sailfish will be entitled to receive an 8% semi-annual coupon payment on the purchase price from Golden Reign.
1 Subject to a 1% per year cost escalation beginning three years from commercial production.
2 Golden Reign will be required to make minimum monthly payments of US$282,800 per month when commercial production commences. Golden Reign, at its sole discretion, may increase the amount of gold delivered and/or cash payments made to Sailfish in order to accelerate repayment and reduce the payment stream percentage.
3 Subject to a 1% per year cost escalation beginning three years from commercial production, plus 50% of the price differential above US$1,200 per troy ounce subject to certain adjustments.
Under the 250tpd PEA scenario, Sailfish may purchase a maximum of 27,878 ounces of gold at an average price of US$703 per ounce (or a combination of gold ounces and cash) in repayment of the US$19.6 million. Thereafter, Sailfish may purchase an additional 119,020 gold ounces at an average price of US$852 per ounce. Total potential gold stream revenues from Sailfish are estimated at US$121 million, representing 22.3% of total gold production. Golden Reign retains 77.7% (513,151 ounces) of its gold production and over 90% of its revenue, valued at US$1,250 per ounce, which is estimated at US$639 Million plus 100% of the silver ounces produced which, valued at US$19.50 per silver ounce, is an estimated US$20.4 Million that will be applied as a by-product credit.
