Show A REPORT ON PIONEER CON J K turner has submitted a report on the pioneer consolidated imenes company pioneer nevada which is as follows the ore deposits as exposed in the property of the pioneer consolidated mines laines corn com ipaty pany occur as irregular masses of altered band and mineralized rock traversed by multitudes of small intersecting fractures containing values certain deposits however exhibit in part more regularity leguia my of form and there is reason to suppose that w a adepts a depth greater than that now reached the ore deposits may take the vein or lode like form but within the mass of rock extending from the surface to the present depth a mass which includes all the ore bodies thus far exploited the deposits cannot de be called lodes or veins without giving to these words unusual meanings or without tacitly ascribing to the mineralized bodies a tabular form that they rarely possess in addition to the th e ore deposits depotts or larger pay shoots small irregular isolated bunches of ore often of high grades are characteristic of this property to open up all the ore bodies under the conditions in such a manner as to render practical the actual measurements of ore reserves would require a large amount of expensive development work which would be of little use for the purpose of mining ore and would entail additional expense in keeping the workings in safe con prior to the removal of the ore as a whole however the development work is of such a nature in the main shaft that it exposes ore reserves that can be technically measured and called ore in sight the ore in sight in the mine and on the surface of your property is tons of a gross value of the ore called probable ore that will be exposed by further developing the present ore faces cannot with any accuracy be computed due to the character of the ore deposits as mentioned heretofore but by the assays essays obtained from the faces of ore as exposed in the work it is perfectly safe to approximately calculate the probable ore as equal to the value of the present ore reserves from the surface to the present depth large blocks of promising territory still remain unexplored the value of the ore where exposed in the lower workings equals that of the upper workings and from the tonnage and value of ore actually exposed and the past performances of the slopes it is reasonable to expect that further development in depth and of the large acreage will be very satisfactory the ore values are found as gold the silver values are so very small at the present development no attention need bo be paid to them the gold is absolutely free but very fine the ore cabbe can be treated successfully by plain stamp mill amalgamation followed by the cyanide process by this method at least ninety per cent of 0 the assay value of the ore can be saved the cost of milling per ton in a 10 stamp amalgamation and cyanide mill should not exceed 2 divided as follows cost of crashing per ton cost of stamp milling and amalgamation per ton 80 cost of cyaniding cyan iding including clean cleanup up total cost the cost of mining per ton not including development work should not exceed 1 the total cost of mining and millin milling can be safely placed at per ton an estimate of the net value of the ore reserves or the ore in sight is as follows gross value per ton gg given iven i ven heretofore 10 1062 62 90 per cent saving of gross value per ton cost of mining and milling per ton net value after deducting cost of mining and milling per ton tol net value of ore reserves the total net value of ote ore reserves wit without hout taking into consideration the probable or pos possible tible ore fully warrants the purchase and construction of a ten stamp amalgamation and cyanide mill having a capacity of at least thirty tons of ore per day the stalny mill at beatty which I 1 inspected spec ted and which has been purchased pur chased by your company is in first class condition and will serve as the crushing stamping and amalgamating portion of your mill the cyanide portion with possibly the excel exception t lon of a slime cabbe can be fully supplied from the gold bullfrog mill the purchase of which is now under consideration by your company should the company not take over this mill I 1 suggest the purchase of steel leach leachel g tanks as well as steel rich solution tanks I 1 would suggest the mill be constructed as near the shaft as practicable this site affords the economical handling of the ore in the mill by gravity I 1 advise the shipping of a carload of average grade ore to some reputable ore testing works so as to get details as to the exact percentage of saving by amalgamation and cyaniding cyan iding costs of same consumption of cyanide size of screen to use on stamps to get the best extraction percentage of cyanide to obtain best results etc etc by securing this data from actual carload tests will aid quite materially and save both time and money in getting the mill in running order as to give the maxi maximum muni saving with the minimum cost I 1 recommend further in the mine with a view of exposing the ore bodies sufficiently to keep mill running indefinitely |
