   Ore Sorting Increases Grade of a Bulk Sample by 55% at Dalradian's 
Curraghinalt Project 
 
   TORONTO, September 18, 2017 /Marketwired/ - Dalradian Resources Inc. 
(TSX:DNA)(AIM:DALR) ("Dalradian" or the "Company") announces positive 
ore sorting test results based on a bulk sample of mineralized 
development material from several of the veins at the Curraghinalt Gold 
Project in Northern Ireland. Testing was carried out by Outotec at their 
TOMRA sorting test facility in Wedel, Germany on approximately 5 tonnes 
of material grading 9.52 g/t Au. Using x-ray and laser technology, plus 
additional screening prior to processing, the amount of non-mineralized 
(waste) material that would be sent to the mill in an operating mine was 
reduced by 35.8% and the grade increased by 54.6% to 14.72 g/t Au with a 
gold recovery of 99.3% (see Figure 1 available at 
http://www.dalradian.com/investor-centre/news-releases/news-releases-details/September-18-2017-News-Release-Figures/). 
Similar results would be expected if implemented into a mine scale 
situation. 
 
   Ore sorting technology has been used in diamond processing operations 
for many years and is now used with a variety of other commodities 
including tungsten and gold. The ore sorting process has become 
increasingly efficient with advancements in x-ray, laser and computer 
technology. It was anticipated that ore sorting would be a good fit at 
Curraghinalt because of the large contrast in density and colour between 
the high-grade quartz-sulphide veins and the surrounding country rock. 
 
   Throughout the testing, the ability to effectively sort the ore from 
Curraghinalt was clearly demonstrated. Using only x-ray technology with 
rougher stage material, waste removal of 50.5% with a gold recovery of 
97.8% was achieved. When the laser scavenger step was added, which is 
used to recover additional mineralized material from the x-ray waste 
material, total gold recovery increased to 99.3% at the expense of a 
decrease in total waste removal to 35.8%. Optimisation of the proposed 
process, including a cost benefit analysis of the secondary scavenger 
circuit, will be needed prior to implementation of the technology. 
 
   Eric Tremblay, Dalradian's Chief Operating Officer commented: "These are 
very good results. Independent testing proves our high-grade gold is 
easily sorted from waste. We can now show that a modest capital 
investment in this technology will improve Curraghinalt's already robust 
grades and project economics. We plan to investigate it further by 
visiting operations using the technology prior to designing our own ore 
sorting infrastructure for inclusion in an updated feasibility study." 
 
   Ore sorting has the potential to considerably reduce costs at the mill 
by decreasing the amount of ore processed to produce the same number of 
ounces. Applying the results of the testing to the Curraghinalt deposit 
Mineral Reserve Estimate, would potentially eliminate approximately 1.87 
million tonnes of non-mineralized material prior to processing (see 
Figure 2 available at 
http://www.dalradian.com/investor-centre/news-releases/news-releases-details/September-18-2017-News-Release-Figures/). 
Using the base case feasibility cost estimate of US$27.8/tonne for 
milling, this could result in savings of US$52 million against a revenue 
loss of approximately US$12.6 million (at 1,250 US$/oz) due to recovery 
being reduced by 0.7%. Further cost savings are expected from the 
replacement of cut and fill mining previously adopted for dilution 
control with mechanized long hole mining. Application of ore sorting 
also has the potential to decrease the cut-off grade, which would result 
in more mineable ounces and increase the throughput of the mine.
