the Mines Branch. From the complete roport the following data
has been extracted.

" eeeeeTho gangue material consists almost wholly of

white, fine-textured vein quartz. .... The following cre minerals

are present: pyrite abundant, marcasite, pyrrhotite, galena,

sphalerite, chalcopyrite, arsenopyritec, limonite, ond free gold.
"Native gold occurs in very close association with the

disseminated type of pyrite, and is present in the polished

sections only where the pyrite is exceptionally abundant Sddo0c
"Analysis showed the ore to contain:

Gold lien 5 O MO Zi Om Ol

Silver = 3.41 ut
Lead = 6.25 per cent
WabNS 9 OAV
Copper = 0.45 a

"Conclusions from Experimental Tests. It is apparent, both from
the character of the ore and from the results of these amalgamation
tests, that a low recovery of the gold content will result from an
simple and cheap method of treatment. The galena in the ore covers
the amalgamation plates so that no gold is saved. |

"Barrel-amalgamation recovers 42.5 per cent of the gold i !
from the raw ore.

"Amalgamation of a concentrate does not effect any
appreciable recovery.

"The ore should be an ideal concentrating rroposition,
preferably by selective flotation .... No cheap and simple
operation on a small scale can be expected to make appreciable

recoveries from this class of material."
