Golden Reign Files NI 43-101 Technical Report and Resource Estimate on the San Albino Gold Deposit
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 01/07/13 -- Golden Reign Resources Ltd. (TSX VENTURE: GRR) (the "Company" or "Golden Reign") is pleased to announce that a National Instrument 43-101 ("NI 43-101") compliant Technical Report and Resource Estimate on the San Albino Gold Deposit on the San Albino-Murra Property located in Nueva Segovia, Nicaragua, as detailed in the news release issued on November 20, 2012, has been filed on SEDAR and is available on Golden Reign's website at www.goldenreign.com. The report was authored by P&E Mining Consultants Inc. ("P&E") of Brampton, Ontario.
The San Albino Deposit is located near the southwest end of a 20 km long mineralized trend defined by Golden Reign as the Corona de Oro belt. The deposit consists of a series of shallow dipping quartz sulphide veins hosted by graphitic argillaceous schist. The San Albino resource model consists of three high grade, vein systems - the San Albino, Naranjo, and Arras veins - over a strike length of 850 metres, a down dip extension of 925 metres, with a minimum true width of one metre and average true width of 2.6 metres.
Only 0.6 square kilometres of the 2 square kilometre San Albino Mine area, within the Company's total 138 square kilometre land package, has been drill tested. All mineralized zones remain open at depth and along strike in both directions.

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 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;
3. 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.
4. Gold Equivalent was calculated on the basis of 1 gram gold = 60 grams
silver.
The resource estimate was derived from applying AuEq cut-off grades to the block model and reporting the resulting tonnes and grade for potentially mineable areas. The mined tonnage from previous operations was insignificant and was not removed from the block model. The AuEq calculation ratio is derived from the following:
Au Price = US$1,592/oz Au Recovery = 95%
Ag Price = US$32.76/oz Ag Recovery = 77%
Therefore the Au/Ag ratio is ($1,572/$32.76)/(95%/77%) = 60:1
The following calculations based on similar open pit and underground operations to that anticipated at San Albino demonstrate the rationale supporting the AuEq cut-off grade that determines the potentially economic portion of the mineralized domains:
Underground Au Cut-Off Grade Calculation ($US)
Au Price $1,592/oz (24 month approx. trailing average
price Oct 31/12)
Mining Cost $48/tonne mined
Process Cost (3,000tpd) $20/tonne milled
General/Administration $5/tonne mined
Therefore, the AuEq cut-off grade for the underground portion of the resource estimate is calculated as follows:
Operating costs per ore tonne = ($48 + $20 + $5) = $73/tonne
(($73)/(($1,592/oz x 95% Recovery)/31.1035) = 1.5g/t
Open Pit Au Cut-Off Grade Calculation ($US)
Au Price US$1,592/oz (24 month approx. trailing average
price Oct 31/12)
Process Cost (3,000tpd) $20/tonne milled
General/Administration $5/tonne mined
Therefore, the AuEq cut-off grade for the open pit portion of the resource estimate is calculated as follows:
Operating costs per ore tonne = ($20 + $5) = $25/tonne
(($25/(($1,592/oz x 95% Recovery)/31.1035) = 0.51g/t Use 0.5g/t
The open pit resource model was further investigated with a Whittle pit optimization to ensure a reasonable stripping ratio was applied and a reasonable assumption of potential economic extraction could be made. The following parameters were utilized in the pit optimizations:
Au Price US$1,592/oz (24 month trailing average price Oct
31/12)
Ag Price US$32.76/oz (24 month trailing average price Oct
31/12)
Au Recovery 95%
Ag Recovery 77%
Ore Mining Cost $3/tonne mined
Waste Mining Cost $3/tonne mined
Process Cost $20/tonne processed
General & Administration $5/tonne processed
Pit Slopes 45 degrees
The above data were derived from similar open pit gold projects to San Albino.

The preceding resource estimate open pit and underground sensitivity tables were derived by P&E by applying a series of increasing AuEq cut-offs to the domains that constrain the mineralization. These domains were subsequently used during the application of all cut-off grades within the sensitivity table.
Technical Report Recommendations
P&E recommends that Golden Reign continue to explore the San Albino Deposit and surrounding area with an emphasis on drilling to expand the resource. Gold mineralization at the San Albino Gold Deposit is open on strike and down dip. P&E has extrapolated the known resources estimate mineralization model and indicates that there is considerable potential to increase the size of the deposit.
P&E has identified an Exploration Target beyond the resource estimate (along strike and down dip) with an estimated 3 to 5 million tonnes at a grade between 6 to 10 grams gold equivalent per tonne. The potential quantity and grade of the Exploration Target is conceptual in nature, there has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in discovery of a mineral resource.
An exploration program consisting of additional trenching and drilling is proposed at the San Albino Gold Deposit. Six trenches, totalling 300 m, are planned to be excavated along the south slope of the San Albino hill to further delineate the surface exposure of the San Albino vein. A further four trenches, totalling approximately 200 m, are planned to expose and extend the surface exposure of the Arras vein. The first phase of a two-phase exploration drill program, to consist of 19,000 m of step-out drilling and 4,000 m infill drilling, will test the down-dip extension and strike extension of all three veins. Phase two drilling, to consist of approximately 30,000 m of step-out drilling, will seek to delineate the boundaries of the San Albino Deposit.
Metallurgical testwork at the San Albino Deposit is warranted to test recovery on oxidized and primary sulphide mineralization. This would be a requirement prior to undertaking a preliminary economic analysis.
In addition to the exploration at the San Albino Deposit, 500 m of trenching and 4,000 m of drilling (40 holes) is proposed in order to test new exploration targets in the San Pablo-Las Conchitas area, which lies approximately 1.5 kilometres south of the San Albino Gold Deposit.
The Technical Report and Resource Estimate was prepared by P&E in accordance with the Canadian Securities Administrators ("CSA") National Instrument 43-101 and resources have been 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 CIM Council.
The Mineral Resource estimates in this news release were prepared by Eugene Puritch, P.Eng. and Antoine Yassa, P.Geo. of P&E, each an independent qualified person, as defined by NI 43-101. Mr. Puritch has reviewed and approved the contents of this news release.
