REPORTS OF TESTS MADE BY H. G. TORREY, ASSAYER U. S. MINT, WASHINGTON. D. C. [District of Columbia]

GENTLEMEN: -- Please find enclosed a copy of the assays reported to you January 21st. These were from samples taken from seven different localities upon your property at Dahlonega, Ga. [Georgia] These samples were concentrated before asaying [assaying], and, exclusive of Nos. [Numbers] 1 and 6, we think that about 50 parts were concentrated to 1; so that the results should be divided by 50 to give the proper assay of the original ore.

This gives $7.22 per ton. It must be remembered that this is the value of the free gold together with the gold combined in the sulphides [sulfides].

After taking our samples we left instructions to have five-ton lots taken out and put through the stamps. This was done, and the tailings from these lots were concentrated on an Imlay concentrator, and seven samples aggregating 1,721 pounds were sent to Captain A. Thies, Manager of the Haile Gold Mine, Lancaster, S. C. [South Carolina], to be treated by his chlorination process. This experiment was to demonstrate, first, would the process apply to these ores, and secondly, how much gold was combined with the sulphides [sulfides] that could not be taken out by the stamp mill.

We submit a copy of the results of these tests made by Capt. [Captain] Thies.

The average of these assays is $29.52 per ton, and excluding Nos. [Numbers] 1 and 6 as being too low and coming from mines rather than open cuts, we find the average to be $38 per ton, or 75 c. [cents] per ton of the original ore used. To obtain the true value of the 23 tons in samples 2, 3 4, 5 (7 and 8), the free gold must be added to the gold obtained by chlorination.

This we find by the report from the mill test made as above stated was from the 23 tons worked $167., to which must be added 75 c. [cents] per ton from the sulphides [sulfides], which gives $17., or $7.75 per ton of the original ore.

This shows a very close result to that obtained from the samples by us, viz. [videlicet], $7.22.
