   Initial revised mineral resource modeling approach for two veins 

   at Curraghinalt show increase in ounces 

   TORONTO, September 11, 2017/Marketwired/ - Dalradian Resources Inc. 
(TSX:DNA; AIM:DALR) ("Dalradian" or the "Company") announces that a 
sensitivity study estimation performed on two of the major veins in the 
Curraghinalt gold deposit (T17 and V75 veins) resulted in a 37% increase 
in grade and a 10% increase in ounces. In the new study, the geology 
wireframes were re-modelled using assays with a heavier emphasis on 
logged geology. This approach yields 24% narrower veins accompanied by a 
20% decrease in tonnage. (See Tables 1 and 2 below.) Composite length 
was adjusted from 0.5 to 0.3 metres to reflect the narrower domains, but 
all other parameters remain unchanged with the aim to isolate the impact 
of re-wireframing. 

   Dalradian assessed the impact of the revised modelling methodology on 
potentially mineable material for the two veins by applying the same 
parameters as those used in the December 2016 feasibility study (FS). It 
was found that the revised vein block models resulted in a higher 
potentially mineable tonnage of 34% and a corresponding increase in 
mineable ounces of 32% at the expense of a marginal decrease in grade 
(1.5%). (See Tables 3 and 4 below.) 

   This change in modelling sequence, where wireframing is carried out on 
geology and assays, followed by compositing within these wireframes, can 
in part explain the positive reconciliation between mill and resource 
(42% more ounces) resulting from the test stopes completed in 2016. (See 
news releases of September 14 and December 8.) 

   Patrick F.N. Anderson, President and CEO said, "We are pleased with the 
results of this exercise, which uses the same drill data to compare the 
impact of wireframing prior to compositing, in estimating the mineral 
resources and resulting mineral reserves at Curraghinalt. The new method 
is the culmination of a great amount of hard work and reflects our 
better understanding of the deposit. The resulting shapes for the T17 
and V75 veins are more heavily influenced by geology as opposed to 
previous models which were largely grade driven. This has resulted in 
smoother, higher grade veins that are only slightly narrower than in the 
previous model. The implications are that we can use longhole mining 
methods more extensively and bring new ounces into the mine plan which 
had previously been below the cut-off grade (see Figure 1). The bottom 
line is that we have 32% more mineable ounces for the two veins tested." 

   Figure 1 is also available at 
https://www.dalradian.com/news-and-events/news-releases/news-releases-details/September-11-2017-News-Release-Figures/. 


   The sensitivity study estimation announced today does not represent a 
new resource update. However, the Company expects that this revised 
wireframing approach will be used in the updated resource estimate 
planned once the current drill program is completed and expects similar 
positive results from the other modelled veins.
