Prof. Chas S. Palmer mentioned an extremely delicate test for tellurium by means of precipitation on foil copper, when the ore is heated with this and sulphuric acid.

Mr. H. van F. Furman called attention to the peculiar characteristics of the gold bullion obtained from the Wauch? Mines at Cripple Creek, which is sent to the Denver U.S. Mint. Even after refining the gold, on clipping the bar, shows a peculiar crystalline structure and is of a brittle nature. Mr. Furman stated that he had no opportunity or facilities for investigating the cause of the peculiarity, but from what Dr. Pearce had said about the nature of the ore, he should ascribe it to small quantities of tellurium in the gold, which had not been eliminated by the refining process.

Dr. Pearce thought Mr. Furman’s hypothesis not an unlikely one, and said that might be drawn to the action of minute quantities of arsenic when alloyed with gold. These are also eliminated only with the greatest difficultly and they also cause the gold to become brittle.

Mr. T.A. Rickard said that Dr. Pearce’s conclusions that the gold in Cripple Creek ores existed formerly as a telluride, and would be so found when explorations penetrated beyond the zone of oxidation, were borne out by the developments at the Anaconda Mine, in which tellurium ores were found in the deepest workings. Mr. N. Anderson presented a number of results obtained by polarizing[?] Cripple Creek ores, and assaying the different sizes obtained by screening, separately. The results, which testing as a whole to demonstrate that the finer portions of the material were richest n gold, did not as a whole enable him to formulate any positive conclusions which he could submit at this time. He would, however, take up the subject in detail at some future meeting.

On motion the meeting then adjourned.

Report

p. 37

Messrs. Diest, Pearce & F. Guiterman presented their report and stated that they had audited the accounts of the Treasurer Mr. R. M. Hosea, and had found same was correct.

Prof. Van Diest had an invitation from the Geological Society in which the Colo. Sci. Soc. Was invited to send a representative to be present in Sand Francisco in the near future. Inquiry developed the fact that said representative was to go at his own expense, which seemed to neutralize any enthusiasm the invitation might have evoked at least no one present claimed the honors of representative of the Society.

p. 39

There being no formal paper to be submitted, Mr. A.A. Blow was asked to give the Society a discourse on the Gold Belt of Leadville. Mr. Blow although quite unprepared willingly complied with the invitation, promising to give the Society in the not far distant future a paper on the subject.

The salient points of the lecture may be summed in

1^st: The locus of the gold ore shoots; these later are embraced in the area lying about 2 miles to the east of Leadville in a comparatively unexplored territory known as “Breece Hill”

2^nd: The tenor of the ore shoots: in regard to this question Mr. Blow called attention to the important fact that this trend was identical with that of a number of prominent ore shoots disclosed on “Iron Hills” and endorsed the opinion that the gold ore shoots would possibly be found to be continuations of the other ore shoots.

3^rd-, the character of the ore. This was highly silicious and but little silver and lead was found associated with the gold.

4^th, - the occurrence of the ore. This was not localized to any special zones. It occurred both in the limestones and in the porphyrys, (both white and gray,) or in the contact plane between the two. In connection with the gold ore deposits there occurred intrusive dykes of porphyries younger than both the white & gray porphyries characteristic in their association with the silver deposits of Leadville, which younger explanations seemed to be intimately connected with the gold deposits under discussion, and appear to have influenced the deposition.

Mr. Blow suggested in conclusion of his address that developments in the gold belt of Leadville might  mostly be awaited with much interest and he apprehended that a thorough study of this especial class of deposits would offer further evidence in negation of Mr. Emmon’s theory that the ore deposits of Leadville owe their origin to lateral secretions which thus drew their pulateric[?] contents from the white porphyry overlying the ore bodies.

Mr. F.C. Knight made mention of a remarkably pure specimens of Naummannite which he had lately analyzed. Unfortunately the locality from which the specimen came was unknown.

The meeting then adjourned

. Guiterman, Secy.

The 112^th regular meeting of the Society was held at the E. Denver High School Bldg. On Monday Apr. 2^nd.

Owing to the absence of the regular presiding officer, Dr. R. Pearce was chosen chairman pro tem.

Twenty persons were present.

The  minutes of the previous meeting were read and approved

Prof. H.B. Patton of Golden, S.S.M. was elected a member.

The Secretary informed the Society that the Executive Committee had determined that owing to the growth of the Society, its library and the collections, the determination had been reached after thorough investigation and discussion to remove from the Society’s present quarters in the High School Bldg. To other location in the Boston Bldg. through the efforts of Dr. Pearce and the kindness of the Hon. H. Wolcott the rooms would be furnished to the Society at comparatively small expense.

It was held by the Executive Committee that the removal of the Society’s quarts to a location more central would be productive of entailing an interest in the Society on the fact of the public, which could not fail to benefit the Society greatly.

It was resolved that a vote of thanks be bestowed to Dr. Pearce for his efforts in procuring the new rooms and the Corres. Secy & Librarian was instructed to present to the Board of Education and Principal Wm. H. Shirley a vote of thanks for the Society in appreciation to the many courtesies shown the Society in allowing it to place, in the past its library and collections in the E. Denver High School Bldg and to use the room for a meeting place.

Dr. Pearce presented to the Society on behalf of Mr. G.W. Goodale of Butte Mountain, a beautiful specimen of tennantite.

Communications

p. 42

Dr. Pearce Commitated[?]a finished paper on Cripple Creek ores. Further investigations confirmed his theory advance in the former papers that the free gold in Cripple Creek ores has been chiefly derived from the oxidation of tellurides, the tellurium being present in the ore in an oxidized form as a host for the presence of tellurium in oxidized form stannous chloride was used.

Dr. Pearce exhibited a specimen on which showed an unaltered and an oxidized portion  He also showed a colored enlarged drawing of the specimen, made by Mr. Stephen Rickard.

Analyses of both unaltered and oxidized portions of the specimens were presented, by which the chemical changes in the ore & rock due to oxidation were clearly shown. The analysis of the weathered rock indicated that the telluride mineral was sylvanite, corroborating the hypothesis brought forward in the previous paper. The conclusions reached were that the gold bearing rock which was subjected to examination was first impregnated with pyrite & sylvanite by means of highly sulphurated waters encrusting through the natural joints; at a later period surface waters promoted oxidation, effecting a change of the pyrite into basic sulphate of iron, the of the tellurium into the oxide.

Mr. F.T. Freeland gave an informal address on the mines of Cripple Creek,

after which the meeting adjourned.

F. Guiterman, Secy.

Reports

p. 46

The curator Mr. R.C. Hills exhibited some mineral specimens of gypsum presented to the Society by Mr. W.S. Ward and also some fossils given the Society by Dr. Wm. P. Headden.

He also brought up the matter of a fossil plant collection which he had undertaken a … with the late Prof. Newberry of Columbia College, N.Y. This collection belonged to Mr. Hills personally, part to the Society and part to Prof. Newberry. A portion of the Society’s then was in possession of Prof. Newberry when he died. Mr. Hills said he had corresponded with the Trustees of Columbia College regarding this Collection and had learned that Prof. Newberry’s main collections had been left to the college, and that it was impossible to … for the Society and him over which that portion of the fossil plant collection which belonged to it. The Columbia College Trustees were …. … willing to enter from the Society that portion of the collection already in its possession and pay for same an adequate monetary consideration. Mr. Hills suggested that in as much as the partial collection was of little use tot h Society the exchange be made, and he was informed by the Ex. Committee to take what action he might deem best.

Mr. W. S. Ward on behalf of Prof. Henry Ward of Rochester, N.Y. made a proposition to the Society to cut from the meteorite a piece averaging from 5 to 8 pounds, polish the face when cut, and pay for the portion cut off in the sum of $200.00 dollars.

p. 53

The Secretary stated that the Director of the U.S. Geol. Survey had during the previous month paid a visit to Denver on his way west, and had expressed a desire to meet the representative mining men and those interested in the work of the Survey. The Society had tendered Mr. Walcott an informal reception  to which a number of Denver’s most prominent citizens had been invited. The time for the arranging of such reception being so very brief, owing to Mr. Walcott’s short stay in Denver, no formal announcement of the meeting could be made to the members through the regular channels and recourse was had to publication in the newspapers.

The meeting was well attended over 50 persons being present.

Mr. Walcott took occasion to outline the nature of the work now being conducted by the Survey and to define the means on which he would be conducted in the future. He explained he expressed himself as highly gratified at the interest shown by the Society in the Survey and trusted the same would always be so conducted as to merit the ardent support of the organization.
