TORONTO, ONTARIO--(Marketwired - Aug. 31, 2016) - Dalradian Resources Inc. (TSX:DNA)(AIM:DALR) ("Dalradian" or the "Company") announces that an internal grade reconciliation study (the "Study") shows an increase of 12% in grade and 16% in ounces contained within a portion of the V-75 vein, which is currently undergoing test stoping, at the Company's high grade Curraghinalt Gold Deposit in Northern Ireland. The Study reconciles estimates of contained gold from the SRK resource model with a Dalradian grade control model from the same area across the full width of the V-75 vein. The Dalradian model is based on tighter-spaced definition drilling of the test stope areas and a higher number of on-vein face and channel samples. Work on the test stopes is proceeding and results will be released as they are received and interpreted.

Patrick F.N. Anderson, Dalradian President & CEO commented,
"This study demonstrates that as the drilling and sampling density is increased, in the portion of the V-75 vein examined, the grade and contained ounces also increase. This pattern is also evident in our mineral resource estimate1 where the grade increases as we move from inferred to indicated to measured and the drill spacing and confidence increase."
The area tested for the reconciliation study (the V-75 Vein Test Stopes) is 40m long by 23m high. The two models are described below and a visual comparison of the amount of data and location can be accessed at http://www.dalradian.com/news-and-events/news-releases/news-releases-details/August31-2016-News-Release-Figures/.
May 2016 SRK Resource Model
- Ordinary Kriged model with 80m-spaced resource drilling and limited face sampling.
- Face samples are capped to 90 g/t Au and drill core samples are capped to 50 g/t Au for the V-75 vein.
- Face sampling data is restricted to a 10m search influence.
- Based on 591 holes for 132.3 km of drilling, for the entire resource.
- All samples composited to 0.5m lengths.
July 2016 DGL V-75 'Grade Control' Model.
- The Grade Control model uses all data available in the first run (all face and channel samples, all grade control and drill hole composites).
- Internal Dalradian July 2016 Inverse Distance Squared model.
- Grade control drilling of 44 Holes (3,300 m) was conducted at approximately 8m spacing to augment the resource stope wireframe.
- Two capping approaches were used on the stoping areas (all samples - face, drill core and channel - capped to 50 g/t Au and all samples capped to 75 g/t Au). There was little variation between the two, showing that the stope estimation was not sensitive to capping strategy. The 75 g/t Au cap approach has been applied for the purposes of this news release.
- The assayed grade from face and channel sampling in the same zones is nearly identical (approximately 3% difference).
- Comparison between Ordinary Kriging and Inverse Distance Squared shows a difference of less than 2%. Comparison between Nearest Neighbour and Inverse Distance Squared shows a difference of 7% or less.
- All samples composited to 0.5m lengths.
1 Curraghinalt hosts a NI 43-101 compliant resource consisting of:
- Measured: 25,000 ounces of contained gold (0.03 million tonnes at 26.99 g/t gold)
- Indicated: 2.07 million ounces of contained gold (5.58 million tonnes at 11.53 g/t gold)
- Inferred: 2.31 million ounces of contained gold (7.13 million tonnes at 10.06 g/t gold)
Note: mineral resources which are not mineral reserves do not have demonstrated economic viability.

Greg Hope, MSc, MAIG, Chief Consulting Geologist, Dalradian Resources, is the Qualified Person who supervised the preparation of the technical data in this news release.
Underground development along veins was sampled by the production geologist via chip panel sampling, across the full width of the face for each round on advance. Distinct geological zones were sampled separately (vein separate from wall rock), with a general minimum-maximum horizontal sample width of 0.10m to 1m and chip sizes approximating 3-4cm. Four to five kilograms of material was chipped with a rock hammer from two thirds the height of each face down to the sill, in volumetric proportion based on relative abundance of mineralization versus gangue. Sample locations were measured from a surveyed control point. Channel samples were saw-cut into the sills of the 170 and 150 western sublevels along the V-75 vein for comparison with face and drill hole sampling.
Samples were submitted to ALS Laboratories in the Republic of Ireland. Quality assurance and quality control procedures identified no material issues. Face and channel samples were analyzed by a 50 gram gold fire assay with either an atomic absorption, or a gravimetric finish for samples initially reporting over 100.0 g/t gold.
ALS Laboratories is accredited by the Irish National Accreditation Board (INAB) to undertake testing, including for Ores and Minerals (INAB P9 703), as detailed in the Schedule bearing the Registration Number 173T, in compliance with the International Standard ISO/IEC 17025:2005 2nd Edition "General Requirements for the Competence of Testing and Calibration Laboratories".
About Dalradian Resources Inc.
Dalradian Resources Inc. is a gold exploration and development company that is focused on advancing its high-grade Curraghinalt Gold Project located in Northern Ireland, United Kingdom. The Company is in the midst of a work program in support of a planning (permitting) application for construction of an operating mine at Curraghinalt. Components of the program include a feasibility study, an environmental and social impact assessment and underground exploration (at least 950 metres of development with associated test stoping).
In May 2016, Dalradian announced an updated mineral resource estimate for Curraghinalt, including a 109% increase in gold ounces contained in the Measured and Indicated categories compared with the 2014 resource. The current resource 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).
