TORONTO, ONTARIO--(Marketwired - May 5, 2016) - Dalradian Resources Inc. (DNA.TO)(DALR.L) ("Dalradian" or the "Company") announces an updated mineral resource statement on the Curraghinalt gold deposit in Northern Ireland, including a 109% increase in gold ounces contained in the Measured and Indicated categories compared with the 2014 resource. As more drilling has been done and the confidence of the resources has increased, the grade has also increased. This updated mineral resource statement, along with reconciliation studies and test stoping, will support the ongoing feasibility study to be delivered in the second half of 2016.
The mineral resources by category are summarized in the table below:
|Mineral Resource Statement, Curraghinalt Gold Project, Northern Ireland, |
SRK Consulting (Canada) Inc., May 5, 2016)
|Resource Category |
(Cut-off Grade of 5.0 g/t)
|Contained Gold |
|Measured + Indicated||5.61||11.61||2,094,000|
|1. Mineral Resource Statement prepared by SRK Consulting (Canada) Inc. in accordance with NI 43-101 with an effective date of May 5, 2016.|
|2. Mineral Resources are not Mineral Reserves and have not 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 US$1,200 per ounce and 95% gold recovery.|
The mineral resources are reported undiluted. In order to arrive at an estimate of the grade and the ounces of gold contained in a minimum vein thickness of 1.0 m, a conservative approach to dilution was applied, using a grade of 0 g/t for wall rock and on a vein by vein basis. The results are summarized in the table below.

Patrick F.N. Anderson, Dalradian's Chairman and CEO, commented:
"The new mineral resource statement, based on more than 130,000 metres of infill drilling, will support a feasibility study to be completed later this year. These higher confidence ounces will be complimented by the results of both an ongoing grade reconciliation study (Q2) and our test stoping program (Q3). Based on the high grade and first-world jurisdiction, Curraghinalt remains one of the best undeveloped gold projects on the global stage."
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 Statement incorporates information from 175 infill drill holes (51,215 metres) as well as 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 infill drilling was successful in increasing the geological confidence of the mineral resources, with Measured and Indicated mineral resources increasing from 1.00 million ounces to 2.09 million ounces.
The Mineral Resource model does not consider the C-veins, unless within modelled D-vein intervals, or any other potential gold contribution from surrounding materials. The model includes 5 new veins (Slapshot, Sperrin, Causeway, Grizzly and V-55) not previously modelled. The diluted quantities and grade estimates assume that the wall rock is barren (0 g/t of gold). Modelling is underway as part of the feasibility study to estimate the effect of the C-veins on diluted grade.
Borehole assay data were composited to 0.5 m down-hole length. In total, 16 veins were modelled as explicit wireframes from the composite data. Overall, 4% of the composites were capped. Capping varied by vein zone and by data type, and was based on grade distribution and statistical analysis. A global variogram model for gold with a range up to 95x95x10 metres was used for grade estimation.
A block model with parent cell sizes of 5x5x5 metres was chosen, with subcells at 0.5 metre resolution. Subcells were assigned the same grade as the parent cell. Block model gold grades were estimated using ordinary kriging, informed by composite data and three estimation runs with progressively relaxed search ellipsoids and data requirements. The first pass required between 5 to 12 composites, with a search up to 95x95x15 metres (variogram range) oriented parallel to the vein. The second pass required between 4 to 15 composites, but permitted a search up to two times the variogram range. The final pass required between 2 to 15 composites within a search radii up to six times the variogram range, with the aim to populate all blocks within the vein. In all passes, no more than 3 composites from one borehole are permitted. Each domain was estimated using a hard boundary approach that considers only the composites from that domain. The influence of underground face samples was limited to within a10 metre radii.
Appropriate validations were undertaken to ensure that the block model adequately represents the informing drilling data. Vein block volumes were converted into tonnage using a relationship established between specific gravity and sulphur estimates. Calculated vein specific gravity varies from 2.51 to 3.06, with an overall average of 2.77. All waste blocks were assigned a specific gravity of 2.73.
The block model was classified using the following criteria:
- The Measured category includes blocks located within 10 metres from underground development;
- The Indicated category includes blocks estimated within the variogram range, by a minimum of 2 boreholes, but more often with at least 3 boreholes; and
- The Inferred category includes all other estimated blocks within a vein wireframe not previously classified as Measured or Indicated.
The automated classification was subsequently manually adjusted to define regular boundaries between categories.
The Company intends to file a technical report pursuant to National Instrument 43-101 to support the updated Mineral Resource Statement on SEDAR and on the Company's website within 45 days of this news release.
The Mineral Resource Statement was prepared in accordance with NI 43-101 under the supervision of Dr. Jean-Francois Couture, PGeo (APGO#0197) and Dr. Oy Leuangthong, PEng (PEO#90563867), both full time employees of SRK Consulting (Canada) Inc. and independent Qualified Persons as defined by National Instrument 43-101.
