The analysis shows the coal to be bituminous. Since the coal mined 
is all from near the croppings and subject to surface influences, it 
varies very greatly in quality as it is supplied at the mouth of the 
mine. Probably much coal of an inferior quality has been sold. 
However, the coal has generally given satisfaction for steaming pur- 
poses, mid the entire product of the mine has found a ready sale to 
the river steamers. 
This mine was first opened up as the Thein mine, a and in 1900 pro- 
duced some coal. Early in L902 it passed into the hands of the present 
owners, and is being developed by Mr. W. E. Williams. In all, about 
1,700 tons of coal have been produced. 
The development consists of a drift 400 feet long in the river bank 
above high water. The greater part of the available coal has been 
stoped out above this tunnel. The coal cars bring the coal to the 
mouth of the mine, where it is piled up on the river bank to be loaded 
on the steamers with wheelbarrows, as no bunkers have as yet been 
built. The other buildings, such as mess house, office, etc., are of a 
temporary nature. Pis. V, B and VI, A show the appliances at the 
mouth of this mine and the method of loading the fuel on steamers. 
About fifteen men in all are employed during the summer season, 
while the mine is in operation. These miners are mostly men who have 
had some experience in the coal mines of the State of Washington. 
Should the demand for coal warrant it, a slope will probably be driven 
to lower levels and a hoisting and pumping plant be provided. With 
such an equipment this mine could no doubt supply all the demand for 
coal on this part of the Yukon for many years to come.
