SATURDAY, OcToBeR 21,1916. - Nos A MINING ENGINEER TALKS ON MINING INVESTMENTS There is much information for the layman in an address recently delivered by John Hays Hammond, the noted mining engineer. Dealing with mines from the investors’ point of view, Mr, Hammond said: it is important for the investor in mining properties to distin- fuish between the two classes of mining. investments—prospects _ and mines, By the term ‘‘prospect’’ the miner designates ore deposits only partially explored or developed. Obviously, investments in this class of mining are always of a speculative character, and for this reason are often referred to as mining gambles, The capital required to purchase and develop a prospect is,of course, much less than that required for the purchase of a developed mine and the installation of the mining and reduction plant necessary for' its ’ exploitation. While financial loss in each particular case of failure in invest- ments of this character is smaller, the losseg are, nevertheless, more frequent, because of the preater inherent risks than in the case of developed mines, This kindof mining should be confined to such capitalists or exploration companies as can afford to incur the risk of several failures before attaining final compensating success, It is difficult, at times impossible, to define at what point in the stage of its development a prospect ends and a mine begins. Itis not always the amount of development work alone upon a property that determines in which category it belongs. For example, some classes of ore deposits, owing to their peculiar geological features, possess such reliability in respect ot the persistency of ore deposits ag to warrant the investor in regarding them a3 mines‘and not as: mere prospects, in spite of 4 relatively small amount of exploratory work actually performed. The famous ore deposits of the Wit- watersrand, in the Transvaal, are examples of mines of this kind. But, in genera} terms, a property msy be dignified by the appelation of mine only when it is sufficiently developed to enable the engineer to make a calculation of the value of the ore reserve, and, in addition to this, to form an opinion as to the continuation of the ore body in depth beyond the limits of the ore in sight—i.e., ore reserves with such a degree of probability as to practically assure the return of the capital invested in the purchase’ of the property and the erection of necessary mining and reduction plants. In their reports mining engineers and experts divide the ore into three classes: first, ore blocked out; second, probable cre; third, possible ore, The ore blocked out is usually referred to as “ore in sight," and can be accurately determined by a competent expert through a careful and exhaustive system: of sampling. In his estimates of probable ore the engineer is confronted with different conditions, because here certainty stops and conjecture - begins,. In determining probable ore much depends upon the personal equation of the engineer. Some ‘engineers ate inclined to allow as probable ore the ore embraced in’a block of ground lying below that actually blocked out to a depth of from twenty-five toin rare cases upward of a hundred feet. Such estimates would depend _in a Jarge degree on the opinions of the. engineers . as to the persistency of the payable ore bodies, In: ‘the case of “possible ore,’’ estimates are obviously highty speculative,and yet I would prefer to take the conjecture,or guess, if you please, of some few engineers because of their :"‘exceptional |. expertness’’, as to how much importance is to be attached to the occurrence of possible ore than to accept from others less qualified}: in this particular kind of mining clairvoyance an estimate of the the “probable ove,” Herein lies the ability of the trained | engineer _ to see “‘beyond the end of the pick”, which was the limit of the ore, reserves and. the probable ore of the old practical miner, who was the mining expert of the past’ generation. ! _ ‘Tt is rarely..that. mining shares are offered: ta- the investing public on. the basis of the net value of the ore: reserves of the mine: that is to gay, the mining investor i is not guaranteed the return of his. entire investment from the net profits to be. derived from the ore reserves. alone, * ‘He must expect to assume the risk. of a part of his ihvestment based on profits to be derived from probable ore, | Ab it is very,seldom that a mine can be purchased on the basis of the net. value of its ore.resetves—i.e., for the net value: in sight —it is of great ‘importance for. the engineer to, determine ; to what}: hopeful spicit in: this: _ vicinity, tiv . extent he can include probable ore in his determination of the vale , of the ming, ° It is,"i indeed,’ ‘upon the degree of risk assumed in. the . “estimatQot Lela i that the be eng neat has to.decide whether he|. ‘TNEWS FROM THE LAKE DISTRICTS Breezy Briefs of Interest Culled From the Happenings About .

Blaynéy, the popular daugher of Mr. and Mrs. Blayney,of Tatalaska Lake, became the , bride of Mr. Frank Burroughs. a neighboring -ran- cher. It was a great day, and made the bachelors around feel rather out of it. Murdock Hay’s cabin had al ‘narrow escape from ‘destruction last week. During his absence his neighbors put out an incipient blaze. Mr. Tuohy’s buildings were in the danger zone. John Keefe has disposed of his cattle, which had the earmarks of a promising herd, Hogs are now taking the at- tention of the ranchers, and it is expected there willbe a goodly number here next year. Throughout the present dry spell there have been two in- stances where blue grass around cabins saved them from fire, as. it is ‘not, so susceptible to frost and keeps green lorg after the other vegetation has died, NORTH FRANCOIS The sympathies of all the set- Jers go out to Mr. and Mrs. Strong in the loss of their little daughter. §.
