GEOLOGICAL SURVEY REPORT ON REGENT
 ALASKA STRIKES

The Interior Department, says a statement issued by the Geo. logical Survey, has received no di- rect official information regarding the actual output of any of these recent gold discoveries in Alaska but they all occur in areas whose general geologic features have been examined in the past, and publications covering which have been issued by the survey and : are available at the government printing office.
 The recently found lodes in the Taku district seem to be in the metamorphic rocks near the in land or eastern border of the great mass of igneous rocks known to geologists as the Coast Range batholith, which stretches almost the entire length of South eastern Alaska. Much ol this eastern margin lies in Canada and a large portion Is in most difficult and inaccessible regions. so that only parts of it have been examined even in a cursory fash ion. Tn the Taku district this eastern order appears to lie some distance west of the information al boundary, So that within the United States territory there is a tract perhaps 10 to Is miles wide that warrants careful prospect ing, though most of the richest finds that have been made So far lie east of the boundary in Can . ada.
 The reported strike in the Wild River district appears to consist mainly in the finding of piece of quartz float which was shot f through with many patches and : filamerts of gold AS the bed- , rock source from which this ma s terial came may be remote from the place where the piece was found, it furnishes no justification for any rush into the district in the hope of finding profitable de- posits at hand. 1t does, however, furnish further corroboration of the long known facts that in the upper Koyukuk region there are
 indications of rich gold mineral
 ization and that diligent search
 there is likely to disclose work
 able lodes or placers. Placers have
 long been mined in this general q region, but no lodeS have yet been
 developed there. The region lies
 in one of the more remote and
 inaccessible parts of Alaska, se
 that developments in 1t are likely
 to be expensive and call for tne
 nersistence and hardihood of the
 best pioneers.
 The reported finds of new pro
 ductive placer ground in the VI
 cinity of Poorman, in the Rub!
 district, have been made in tn' " same general neighborhood Wher' ,- placer mining operations hav' ,f been carried on for many years ol To judge from the meager de l. tails available, the new discov
 cries seem to have disclosed pla
 cers formed under essentially m II same conditions as those alread. 4r known In that region. Althougi = I,reports from this camp of pan
 of gravel carrying many dollar
 in gold are probably true, 1t
 likely to be several months pe
 fore any real estimate of tn ,o production from this find will o available, for by the process Q : mining used, the operators VII nrobably store the gold-bearin
 gravel mined during the wlnte
 nntil the summer, when wate
 will be available to wash ava f' the gravel and thus separate T. from the heavy gold, which IS iei
 behind. From what is known Q
 the Ruby region 1t seems hKel " that there remains workable pla 1e cars that have not yet been ois sd covered and probably will well re
 nay thorough and intelligent pros
 pecting. sd The discovery of placer tha tn will quickly yield a few thousan $. dollars in gold to the owner ma
