of the ore mined. IL the whole 472.. IS3 tons had been milled. the free gold recovery would have been about $l.5O per ton. as the rejected vein matter is also gold bearing. It Is i'm portant to note that an attempt was made to save the values in sulphides which. If saved. would have added about 20 cents per ton. A tailing loss Of an equal amount Is known. so that the total v1lue per ton would approx. innate g. All of the above ere. 1t must be noted. was from selected sur. face workings scattered over the best known portions of the vein.
 The Gold Creek or main working tunnel. at an elevation of 425 feet above sea level. has been driven since the above surface mining and milling work. and at a point 645O feet from the portal an incline has been put through to the surface.
 ''In driving the Gold Creek tunnel. portion of the vein on the west side of the Silver Bow Fault was cross cut diagonally for a distance of $50 feet. disclosing bodies of ore. the as- say values of which average slightly less than g per ton.
 The ore extracted from both the Gold Creek tunnel and the intermed- fate level opened from the incline raise at an elevation of 495 feet above the Gold Creek tunnel. has been milled in the new mill erected on Gastineau channel Because of the mixture of waste with the ore, due to opening up of these two elevels preparatory to stoping. the mill feed assay value of 50.000 tons milled up to December 1st. 1914. averages $1.36 per ton. The December and January results, however. more nearly approx. innate the expected conditions, be cause of less admixture of waste. and are as follows:
 December, 1914:
 Assay Value Sorted ore ...2 2OO5 tons s2OO per ton 1 Run of mine
 ore ................7652 tons 1.66 per ton Total and av 9657 tons $l.74 per ton | January. 1915:
 l Sorted ore Hoo tons $3.12 per ton Run of mine
 | ore ..............79 1900 tons 1.56 per ton Total and av 12000 tons $2.O9 per ton
 Tn addition to this we have the past milling records of the Perseverance now part of the Alaska Gold Mines Company. which adjoins the Alaska Juneau on the eastern end, all of which indicate value more or less closely approXimating those above given.
 The cubic contents of the vein above the Gold Creek tunnel level and between the eastern and west ern ends of the property, totals, ap proximately 500.OOO.0O0 tons of slate metagabbro and quartz. From this there should be mined. from selected places, S0,000.000 to 100000. .OOO ton. of vein matter and quartz suitable fol milling that should yield a net profit of from 70 cents to $1 per ton. de pending upon conditions of mining that cannot at this time be estimated within close limits of ultimate profit Areas will probably be found in which mining may profitably be conducted by sorting, leaving two tons in the stopes for every ton milled. Other areas will probably be found, all O. which may be mined without the ne cessity of mine sorting.
 The mining chances below tht Gold Creek tunnel level promise ar addition of twice as much tonnage O. the same value as we believe the veir will yield above the Gold Creek tun nel. These mining chances are based upon the fact that in a parallel weir two miles away on Douglas island tho ore bodies are now being mined at { depth of 2000 feet below sea level All that depth. the Douglas Island ort bodies still hold their size and aver age values.
 "lt is estimated that with the ex penditure of funds realized from th' sale of the shares of stock for the de } velopment and equipment of the prop erty. the company will be able to carr at least $1.40O.O00 per annum."
