TORONTO, ONTARIO--(Marketwired - Dec. 12, 2016) - Dalradian Resources Inc. (TSX:DNA)(AIM:DALR) ("Dalradian" or the "Company") is pleased to announce the results of the independent Feasibility Study ("FS") prepared in accordance with National Instrument 43-101 ("NI 43-101") for its 100% owned Curraghinalt Gold Project ("Curraghinalt" or the "Project") in Northern Ireland. Unless otherwise stated, all dollar amounts are quoted in U.S. dollars ("$").
Patrick F.N. Anderson, Dalradian's President and CEO, commented:
"The Feasibility Study outlines a project with high expected profitability and returns and demonstrates the strong economic case for advancing Curraghinalt to development. One of the project's main competitive strengths is the high reserve grade, which would place it in the top 10% of gold mines world-wide1. What is also very encouraging is that there are multiple opportunities to enhance the economics and extend the project life.
We are particularly pleased that our test-mining showed the viability of mechanized underground mining methods for this deposit and returned consistently higher grades than those predicted by the resource model. The FS sensitivities demonstrate considerable potential for grade upside, such that a 20% grade improvement increases after-tax NPV by 64% and after-tax IRR by 39%."
We aim to build Europe's leading gold mine using best-in-class mining, processing and environmental standards, while facilitating economic development in Northern Ireland with the creation of at least 350 permanent jobs during operations. We recently held community consultation events on the proposed mine, with more than 270 people in attendance. We are addressing community consultation feedback and incorporating it into our plans wherever possible."

Feasibility Study Highlights
- Net Present Value ("NPV") of $301 million (CDN$402 million) after tax (at a 5% discount rate) and
Internal Rate of Return ("IRR") of 24.4% after tax, at an assumed gold price of $1,250/ounce
- Proven & Probable Mineral Reserves of 1.44 million ounces of gold and 0.66 million ounces of silver (5.24 million tonnes at 8.54 g/t Au and 3.9 g/t Ag), a subset of the Measured and Indicated Resources of 2.10 million ounces of gold (5.61 million tonnes at 11.61 g/t Au). The FS excludes Inferred Resources of 2.31 million ounces of gold (7.13 million tonnes at 10.06 g/t Au)
- Life of mine ("LOM") production of approximately 1.36 million ounces of gold and 0.38 million ounces of silver over an initial 10.5 year mine life using an average overall gold recovery of 94.3%
- Average annual gold production of 130,000 ounces in first 10 years with an average LOM total cash cost of $556/oz and a LOM all-in sustaining cash cost ("AISC") of $674/oz
- Estimated initial capital cost, including contingency, of $192.0 million with payback of 4.0 years, and LOM sustaining capital costs of $165.1 million
- At year five, production increases above 150,000 oz/yr, with peak production achieved in year 7, at 170,000 ounces. There is potential to maintain this higher rate of production beyond year 7 with conversion of existing Inferred Mineral Resources
- Curraghinalt will be operated using automation, mechanized underground mining methods and best-in-class processing. The dry stack tailings from the process will not have not come into contact with cyanide.
- Creation of several hundred new jobs: during the 18-24 month construction period, direct employment is estimated to be at least 300; once the mine is in operation, it is expected to employ at least 350 people in permanent positions
Project Enhancement Opportunities
There are numerous opportunities to further enhance Curraghinalt project economics including:
- Enhancement of the deposit grade via tighter drill spacing and detailed definition of high grade ore shoots within mineralized zones (see Figures 1 and 2, all figures referenced in this news release can be accessed at http://www.dalradian.com/news-and-events/news-releases/news-releases-details/December-12-2016-News-Release-Figures)
- Mine life extension from (i) conversion of Inferred Resources to Measured and Indicated Resources and then into reserves with infill drilling and (ii) overall resource and reserve growth from step-out drilling along strike and at depth combined with exploring the potential for new veins parallel to the those already defined
- Reduction of operating costs with additional geotechnical programs to maximize long-hole mining methods
- Ore sorting technology to increase the grade and reduce the tonnage of material entering the processing plant. Test work is currently underway and shows positive preliminary results, with final results expected in H1 2017.
The FS was prepared under the direction of JDS Energy & Mining Inc. ("JDS"), an international engineering firm with extensive experience in both the construction and operation of mining projects. The study was supported by SRK Consulting, and is being summarized into a Technical Report (the "Dalradian Technical Report") to be filed on SEDAR in accordance with NI 43-101. The FS confirms that the Project is expected to support an economically viable and robust, high grade underground gold mine.

Gold Price Sensitivity
The Project sensitivity analysis shows that a $100/oz variation from the base case gold price had the following impact on the Project after tax economics, with silver held at $17/oz.
Table 3 - Gold price sensitivity
||Base Case $1,250/oz
The Project sensitivity analysis indicated that variations from the base case gold grade had the following impact on the Project after tax economics, with silver held at $17/oz.
Table 4 - Grade sensitivity
Combined results from three test stopes completed in 2016 demonstrated a 50%-plus improvement in gold ounces recovered compared to the resource model on the V-75 vein (see news releases of September 14, 2016 and December 8, 2016 for details). This is a direct result of a higher than expected grade in those areas. At a broader scale, the resource table below shows that tighter drill spacing results in higher grade with gold grades increasing from 10.1 g/t in Inferred, to 11.5 g/t in Indicated to 27.0 g/t in Measured.
Economic Benefits to Northern Ireland
The FS confirms that development of Curraghinalt is expected to provide substantial economic benefits to Northern Ireland at the local, county and national levels, including:
- During the 18-24 month construction period the project is expected to generate direct employment of at least 300 people
- When the mine is in operation, it is projected to directly employ at least 350 people in permanent positions, excluding any contractors and support staff
- It is estimated that the mine will pay annual wages of approximately $26 million (£21 million) to direct employees
- We believe the project will also generate several hundred indirect jobs with suppliers of products and services to support mine operations
- Based on a gold price of $1,250 per ounce, the Project is anticipated to generate average payments annually to the Government totalling approximately $21 million (£18 million) in the form of income tax, corporate tax and national insurance contributions
- Training and skills development aimed at maximizing local employment at the project
- Expected improvement of local and regional infrastructure
- Continuation and increase of existing community investment programs, small business development and support of cultural development
Note that according to regulations a feasibility study is only permitted to incorporate Measured and Indicated resources in its calculations. Measured and Indicated Mineral Resources represent less than 50% of total Mineral Resource ounces identified to date at the deposit. However, the Environmental and Social Impact Assessment ("ESIA") and Planning Application will take into consideration the Inferred Mineral Resource with a view to permitting a mine with a life of greater than 20 years.
FEASIBILITY STUDY DETAILS
The Curraghinalt gold deposit is an orogenic gold system consisting of a series of moderately to steeply dipping, structurally controlled, high-grade gold bearing quartz-carbonate veins. The deposit remains open in all directions. The Mineral Resource estimate incorporates information from 175 infill drill holes (51,215 metres) and underground samples from new and existing drifts along the T17, Sheep Dip, 106-16, V-75, Slap Shot and No. 1 Vein Zones. The Measured Mineral Resources are higher grade than the Indicated and Inferred Mineral Resources.
The current Mineral Resource estimate consists of 2.1 million ounces of contained gold in the Measured and Indicated categories (5.61 million tonnes at 11.61 g/t) and 2.3 million ounces of contained gold in the Inferred category (7.13 million tonnes at 10.06 g/t gold).

|2. Mineral Resources are not Mineral Reserves and have no demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, marketing, or other relevant issues. The Mineral Resources have been classified according to the CIM Definition Standards for Mineral Resources and Mineral Reserves (May 2014).
|3. All figures have been rounded to reflect the relative accuracy of the estimates.
|4. The Mineral Resources are reported at a cut-off grade of 5.0 g/t gold, based on a gold price of $1,200 per ounce and 95% gold recovery.
Mineral Reserves and Mining
The estimated Mineral Reserves, presented by reserve class, are shown in the following table. The overall diluted gold grade of the mineralized material going to the mill is estimated at 8.54 g/t.
Table 6 - Probable Mineral Reserves as at December 12, 2016
- The Qualified Person for the Mineral Reserve estimate is Michael Makarenko, P. Eng., of JDS Energy & Mining Inc.
- Mineral Reserves have an effective date of December 12, 2016. All Mineral Reserves in this table are Proven and Probable Mineral Reserves. The Mineral Reserves are not in addition to the Mineral Resources, but are a subset thereof.
- Mineral Reserves were estimated using a $1,200/oz gold price and gold cut-off grade of 5.0 g/t. Other costs and factors used for gold cut-off grade determination were mining, process and other costs of $165/t, transport and treatment charges of $6.00/oz Au. A royalty of $71.50/oz Au and a gold metallurgical recovery of 94% were assumed.
- Silver was not used in the estimation of cut-off grades but is recovered and contributes to the revenue stream.
- Tonnages are rounded to the nearest 1,000 t, gold grades are rounded to two decimal places, and silver grades are rounded to one decimal place. Tonnage and grade measurements are in metric units; contained gold and silver are reported as thousands of troy ounces.
- Rounding as required by reporting guidelines may result in summation differences.
The Curraghinalt deposit is expected to be accessed by the existing exploration adit and a new ramp to be developed adjacent to the proposed plant site. This new ramp will serve as the primary access to the mine for personnel, materials and haulage of mineralized material to the plant site. Annual ore production of up to 511,000 tonnes (1,400 tonnes per day) is planned from a combination of primary longitudinal long-hole retreat, with some cut & fill mining methods and development along the veins. Sub-levels are set at 18 metre intervals (floor to floor) with primary cross cuts spaced approximately 200 metres apart to access the 16 mineralized veins in the deposit. The recent test stoping program at Curraghinalt successfully demonstrated the long-hole mining method at vein dips ranging between 55-75 degrees with good control on dilution. In zones of more challenging ground conditions or shallow dip, methods including cut & fill and uppers retreat will be used.
Curraghinalt mineralization is expected to be processed using a crush, grind, flotation and leach flowsheet to recover gold and silver into doré. Extensive metallurgical test work has shown overall gold and silver recoveries of 94.3% and 57.9% can be expected over the LOM using a coarse primary grind size of approximately 80% passing 240 microns. Gold in sulphide is concentrated in the flotation process with an average mass pull of 11.2% with over 97% of the gold recovered. After re-grinding the concentrate to approximately 80% passing 50 microns, the leaching circuit recovers approximately 96% of the gold after 48 hours of retention time. The process plant uses the industry standard S02/air treatment process to destroy the cyanide and directs the tailings to the paste backfill plant to be stored in the underground mine. Tailings from the flotation circuit, which will not have come into contact with cyanide, are expected to be filtered and placed as dry stack material in the mine waste storage facility and also used to complete the underground paste backfill requirement. Throughout the process, water is expected to be recycled and returned back to the process plant to minimize the impact on the environment. The water treatment plant includes reverse osmosis.
Capital & Operating Costs
The initial capital cost is estimated to be $192.0 million. This capital cost was estimated under the assumption that any expenditures by the Company prior to the start of construction are a sunk cost and are not included the estimate shown in Table 7. The sustaining capital is estimated to be $165.1 million including reclamation and closure costs.
Table 7 - Capital Cost Summary
|Mining incl. Paste Plant
|Crushing & Handling

The LOM operating cost estimate is $143.94 per tonne of mineralized material. The operating costs were estimated based on process design criteria, equipment lease rates (if applicable), labour, reagents, power, fuel, explosives, maintenance and other miscellaneous costs. All costs are in Q4 2016 dollars and noted in Table 8 below.

The Curraghinalt project has the advantage of being located approximately 100 km west of the City of Belfast and approximately 60 km south of Derry/Londonderry, both of which have port facilities. The proposed site is in a natural hollow surrounded by mature trees and near to the communities of Greencastle, Rouskey, Gortin and Omagh. The site is accessible by major highways with grid power and other services close by.
The power requirements are expected to be met by an extension to the regional high voltage transmission network. A single circuit 33 kV dedicated transmission line, 40 km long, will be built to feed the Project.
