PRAISES THE HYPOTHEEK
Engineer George Huston has Assays
Made of Rich Ores Found There.

Aside from the Snowstorm output the Coeur dAlene region
promises to become much greater producer of if the ev
dence cleaned from the certain exhaustive recently
peted the laboratory of Stowe Co. any criterion
Several samples of Hypoheek copper lately submitted
Gorge Huston the Occur Aene geolog for study dark
lead mineral mscaled gray found by him to
be chacoci copper glance rich suphde of "copper" and
coming it did from the lowest levels the NINE he quick
to attribute its to the working principles secondary
enrichment The Importance of this phenomena is discussed by
Mr. Huston says the Inland Herald.
The process of secondary enrichment has been of great
in the copper Of Mount Morgan Australia Butte
Bingham Clifton in Nevada and many Others he said in
sponse to question of precedent.
The deposits at the top comparatively lean of other
metals Surface water attacked the copper minerals causing the
mpregnated solutions flow down the much faster than
the top portion was removed by erosion.
The copper liquors flowing the eaner lower miner
ais acted upon em removing certain easily dssovabe portions
replacing with copper from the liquors highly
traed form mineral Thus chalcopyite containing 345 per
"copper" when pure enriched into cacocte ance
ing per "copper" Above the of enrichment may be-
eached barren and below will come in the original lean vein
again.
The analytical work done by Mr. Harry Stowel proves
cusvey that the chemical reactions governing the
there The submitted fine grained yellow chacopyre
with border of lead chacoce mbedded smoky quartz
gangue Samples taken of the puest chacopte and also
of the chalcocite.
The average analysis of the first gave 1919 per "copper"
while the second gave copper Care taken to have
samples off the sapece The enrchg the test proceeded
was found to be concdent with the change from the yellow Of
chaopyte to the lead chacoce and working from the
.periphery toward the centre of the sample.
What makes this the interesting is its in
the Pchard states Of the Occur dAene sedmenary series
These states hitherto been looked akance by experienced
mining The Hypoheek formationay considered has gone
deeper into the Pcad than any other me and E therefore,
geologicaly, the deepest mine in the region
Fndng chalcoce of richest of down 1000
feet below the Burke formation well for the future There
lis large stretch country known to be favorable in the vicinity
Of the and result the should give added acv
ity to the prospecting effort
II have not visited the Hypotheek for At that
time nv attention drawn wide OF barren mixed
quartz and slate filled with cavities containing iron oxide. That
the mine waters this level highly curferous atteste
by the conversion the track spikes into o
tin pieces Of air pipe and drill steel had grown into
cement copper suggested that enriched likely be
found below The suggestion acted by sinking 1000
foot DEPTH do not what the extent Of the body
the bottom levels
is occurrence opens up large question The lead mines
Of the region are supposed lie the formation above the Prich
ard slate These are the Burke Rev and ST. Regis situated
respectively 2 5000 and 1900 feet in thickness above The
finding Of copper 1000 below the Burke in the Prchard slate
would lead to the query Doe undere the lead mines OF
the Coeur Plenty of precedent exists that it does else
where At Bingham Utah. for instance the butte surface ores
were silver Mount Morgan Australia was gold mine before
turning into and we hard nuts to crack profess
onay before We can say that the states end the producing
activities Of our wonderful Occur d dAlenes,
