Initial revised mineral resource modeling approach for two veins at Curraghinalt show increase in ounces

TORONTO, ONTARIO--(Marketwired - Sept. 11, 2017) - 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."

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.

FORWARD LOOKING STATEMENTS

This press release contains "forward looking information" which may include, but is not limited to, statements with respect to future financial or operating performance of the Company and its subsidiary and its mineral project, the future price of metals, test work and confirming results from work performed to date, the estimation of mineral resources and mineral reserves, the realization of mineral resource and mineral reserve estimates, the timing and amount of estimated future production, costs of production, capital, operating and exploration expenditures, costs and timing of the development of new deposits, costs and timing of future exploration, requirements for additional capital, government regulation of mining operations, environmental risks, reclamation expenses, title disputes or claims, limitations of insurance coverage, the timing and possible outcome of pending regulatory matters and the realization of the expected production, economics and mine life of the Curraghinalt gold deposit. Often, but not always, forward looking statements can be identified by the use of words and phrases such as "plans", "expects", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", or "believes" or variations (including negative variations) of such words and phrases, or statements that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved.

Forward looking statements are based on the opinions and estimates of management as of the date such statements are made and are based on various assumptions such as the continued political stability in Northern Ireland, that permits required for Dalradian's operations will be obtained on a timely basis in order to permit Dalradian to proceed on schedule with its planned exploration and mine development, construction and production programs, that skilled personnel and contractors will be available as Dalradian's operations commence and continue to grow towards production and mining operations, that the price of gold will be at levels that render Dalradian's mineral project economic, that the Company will be able to continue raising the necessary capital to finance its operations and realize on mineral resource and mineral reserve estimates and current mine plans, that the assumptions contained in the Company's Technical Report dated January 25, 2017 are accurate and complete, that the results of the ESIA will be positive and that a permitting application for mine construction will be approved.

Forward looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of Dalradian to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. Such factors include, among others, general business, economic, competitive, political and social uncertainties; the actual results of current and future exploration activities; the actual results of reclamation activities; conclusions of economic evaluations; meeting various expected cost estimates; changes in project parameters and/or economic assessments as plans continue to be refined; future prices of metals; possible variations of mineral grade or recovery rates; the risk that actual costs may exceed estimated costs; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry; political instability; delays in obtaining governmental approvals or financing or in the completion of development or construction activities, as well as those factors discussed in the section entitled "Risk Factors" in the Company's Annual Information Form for the year ended December 31, 2016 dated March 23, 2017 (the "AIF").
