Stockton Mine: update on Mammoth seam development, production and sales.

The Board of Atlantic Coal, the AIM listed anthracite coal mining company operating in Pennsylvania, USA is pleased to provide updates on the development of the Mammoth seam at its Stockton Mine, together with updates on the Company's recent anthracite production and sales. Atlantic Coal owns and operates the Stockton Mine ("Stockton") which is located near Hazleton, Pennsylvania.

Mammoth seam

The Mammoth seam has now been uncovered in the current mining cut at the bottom of the basin at Stockton. As anticipated from the study of old underground mine plans, the seam is almost solid anthracite, containing very few old mine workings and averaging 30 feet in thickness.

This anthracite seam of will be worked over the coming months, providing both feedstock for the production of clean anthracite products and raw anthracite for sale to other processors. It is anticipated that the next cut will reach the bottom of the basin again in the latter part of 2016 and as excavation progresses the directors believe that substantial quantities of anthracite will also be recovered from the shallower 'Primrose', 'Orchard' and 'Diamond' seams, as well as from the Mammoth seam in the limbs of the synclinal basin.

Anthracite production

For the ten months to 31 October 2015, Stockton anthracite production was 164,328 tons. This represents a 26% increase relative to the ten months to 31 October 2014, where production was 130,357 tons and represents 99.6% of the total production of 165,052 tons achieved in the full year ended 31 December 2014.

Anthracite sales

Clean anthracite product sales from Stockton for the ten months to 31 October 2015 were 151,384 tons and raw (run of mine) sales were 69,205 tons, a total of 220,589 tons. With respect to clean anthracite product, this represents an 18.5% increase on the ten months to 31 October 2014 figure of 127,780 tons and represents 98.5% of the total sales for the full year ended 31 December 2014 of 153,662 tons. Raw anthracite sales only commenced in the spring of 2015.

October 2015 was a record month for clean anthracite product sales, with 24,066 tons sold. Raw anthracite sales for the month were 2,825 tons.

Atlantic Coal's Managing Director, Steve Best, said: "The excellent performance of our Stockton Mine continues with record year to date production and sales. As we still have two months of production and sales left in 2015 we are confident of beating our previous record production and sales by a significant margin. It is particularly pleasing to see a record monthly sales figure in October and this, together with our healthy inventory of both clean anthracite product and raw anthracite gives us confidence for Stockton's performance for the remainder of 2015 and the winter season running into 2016.

Our investigation of old underground mine plans had indicated that that we were approaching areas of thick Mammoth seam which were largely unworked, but as mining is never predictable we could not be certain of this. We are, however, now on our second cut of 30 feet thick almost solid Mammoth seam and this gives us a high degree of confidence that this will continue over the rest of the life of Stockton Mine."
