TORONTO, ONTARIO--(Marketwired - Apr 16, 2014) - Dalradian Resources Inc. ("Dalradian" or the "Company") (DNA.TO) announces an updated mineral resource estimate for its 100% owned Curraghinalt gold deposit, located in Northern Ireland.
- 114% increase in Measured and Indicated resource to 1.0 million contained gold ounces at a 5 g/t gold cut-off and an increase of 12% in Inferred resource to 2.49 million contained gold ounces
- The average horizontal width of this resource is 2.57 metres while the minimum horizontal stope width contemplated in the 2012 PEA mine plan was 1.8 metres, which resulted in a head grade of 8.1 g/t gold
Gold resources by category are summarized in the table below:
|Curraghinalt Mineral Resources |
(as at January 20, 2014)
|Resource Category |
(Cut-off Grade of 5.0 g/t)
|Contained Gold |
|Measured + Indicated||3.00||10.41||1,004,100|
|1.||Resource Estimate prepared by T. Maunula & Associates Consulting Inc. with an effective date of January 20th, 2014.|
|2.||Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, marketing, or other relevant issues. The Mineral Resources in this news release 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 CIM Council.|
|3.||Contained metal figures and totals may differ due to rounding of figures.|
|4.||The resource is reported at a cut-off grade of 5.00 g/t gold, consistent with the 2012 PEA and the 2011 resource.|
|5.||Block grades were interpolated using Inverse Distance Weighting with a Power of 3 (IDW3) in Minesight software.|
"Our infill drill program has more than doubled our M&I ounces at Curraghinalt," commented CEO Patrick F. N. Anderson. "We used wider resource envelopes which will likely require less dilution in an eventual mine plan than was required for the previous narrower resource envelopes. This new modelling approach simply incorporates more dilution upfront. We have also developed a superior geological model that will allow us to better target additional ounces with a modest amount of drilling. Our deposit remains open in all directions."
The Curraghinalt gold deposit is a lode gold system consisting of a series of steeply dipping, structurally controlled, high-grade gold bearing quartz-carbonate veins. The deposit remains open in all directions. The Mineral Resource estimate incorporates 80,976 metres from 406 drill holes as well as underground channel samples from existing drifts along the T17, Sheep Dip and No. 1 Vein Zones. Incorporation of the approximately 29,000 m of drilling completed since the 2011 Mineral Resource estimate has increased the geological confidence, with contained Indicated gold resources increasing from 460,000 ounces to 989,000 ounces. In addition, the contained Inferred gold resources increased from 2.2 million ounces to 2.5 million ounces. The Mineral Resource estimate does not include C-veins except where C-veins were identified in close proximity to main veins. Future modelling efforts are planned to address the C-veins.
This mineral resource model is based on a complete re-interpretation of the vein zones. In total 12 vein zones were modelled and assay data was composited to 1 m down-hole length. Mineralization envelopes were defined for each vein zone using a minimum of two 1 m composites. Overall, 1.9 % of the composites were capped; capping methodology varied by vein zone and was based on grade distribution and statistical analysis. Globally the average horizontal thickness of the interpreted mineralization envelopes is 2.57 m.
Block model gold grades were estimated in two passes and search ellipse orientation varied by vein zone. The first pass used a minimum of one composite and a maximum of eight composites with a maximum of two composites per drill hole. The search ellipse dimensions were 200 m X 100 m X 200 m. The second pass used a minimum of three composites and a maximum of eight composites, with a maximum of two composites per drill hole. The search ellipse dimensions were 100 m x 50 m x 100 m.
Appropriate validations were undertaken to ensure that the block model adequately represents the informing composite data. A bulk density of 2.85 t/m3 was used for all vein zones.
Resources were classified based on using a minimum of two drill holes and three composites for grade estimation. Categorization of mineral resources was done based on the following criteria:
- Measured mineral resources include blocks within 6 metres from underground development, the nominal spacing (distance to nearest composite) was 10 m;
- Indicated resources were based on a maximum distance to the nearest composite of 30 m with a nominal spacing of 20 m; and
- Inferred resources were based on a maximum distance of 125 m to the nearest composite with a nominal spacing of 72 m.
The Company intends to file a National Instrument 43-101 ("NI 43-101") compliant technical report in respect of the updated mineral resource estimate on SEDAR and on the Company's website within 45 days of this news release.
