<br />GEOLOGICAL FORMATION. _3
<br />The geological features in general of any individual property of the group will apply equally
<br />to all, It is principally archaean granite, generally conceded to be the olrlesr and deepest of a!1
<br />Inn.~;:n tracks. Tltis formation is traversed in all directions by sparry veins of al] sizes, consisting
<br />of q'.~nrtz or feldspar, or hotly generally known as pegmatite, quite an amount of which was noticed
<br />in Freeland, Toledo acid Split veins. There is also notch gneiss and schist intermingled with the
<br />gr,~Jte, and, as a result, the rocks are contorted and intermingled into almost every conceivable
<br />sha;~c. Granite, gneiss and schist are here curiously and in~egularly bander) in folds and layers,
<br />7•hc. schist is mostly black: Numerous varieties of these rocks are found in varying comhina-
<br />lio:r: within very short distances. As revealed by surface and underground inspection, this '
<br />ground is.traversed by porphyry dykes, general strike of which seems to be northeast and south-
<br />nz:a-general course of lodes in this group. The veins of this group, ko the extent of my investi-
<br />gatinn, are of the same general character as Co lining, both mioeral and gaogue, and are undoubt-
<br />wily fissure; mostly strong and well defined, and will undoubtedly extend beyond any depth
<br />within the power of man and machinery to operate.
<br />THE §3,500,000 VEIN•
<br />7•he vein filling consists principally of au altered form of the country roc):, through which
<br />the rent or fissure has been made, mingled with dyke porphyry, quartz and spar, sometimes
<br />pricing entirely into the porphyry, which, in my judgment, would cause scattering or lowering
<br />of the values from the mineralized flow. In places the porphyry forms a wall, clean and well
<br />dcllned, in which event the mineralized flow carries a sG~onger identity, and values should 6e i
<br />concentrated and continuous. Taking fully into consideration the fornuuimt Irene (the oldest
<br />launrn), and the fact of portions of veins on this property having been worked for over thirty ~
<br />years at a profit, ample proof of which was submitted me, I conclude that the ore in these veins '~
<br />is of sufficient Continuity, or shoots of such frequent occurrence, as to render (air returns, et ~ -
<br />Icasl to modern, systematic and economical mining' methods. To me there is no reason apinrent
<br />why the values should not be persistent with depth, fully considering' the above reasons for scat- i.
<br />trring~ or decreasing of same at intervals.
<br />"1'he above conclusions were drawn chiefly from underground inspection of the Freeland,
<br />"I'ulc~lo and Split veins and three or [our adjaccot properties uof embraces! in this group. In
<br />:uldiliou, a general inspection of the surface of all the ground embraced in this group was made.
<br />The ore in these veins carries values iu gold, sitvev, to~iher mart )cart, as sulphides, the three latter i
<br />lciug~ commonly ]mown as sulphurets (limited quantity tto[iced),(~yrrles rtvedgalcan, respectively,
<br />tciili gold found in all, as"well as in iron pyrites, tehich is the most abundant of all the visible
<br />fnrinnlions of the ore. Neither free gold nor zinc was noticed. Same carhon;ues of lead, prob- it
<br />;ihly containing silver values also, was noticed, but in limited quantities. The general character
<br />of this ore is such as to rendet• it a desirable smelling product, when values warrant, especially t
<br />the cuucen[rates, from which the greater pm•t of silica has been eliminated. I;
<br />DEVELOPMENT, ~ ~ -
<br />The only development work of importance on ibis group, aside from prospecting and the
<br />mressary amount to secttt•e putenC, is oa the Freeland, "foledo :uul Split veins. "I'he former tuts i'
<br />hero worked very extensively by a series of adit levels and :m incline shaft sunk ou the hreeland '',
<br />seta to a rlcpth of about eleven hundred feel. The total amount of linear work done in this j
<br />mine is probably in excess of four miles. The vein is ~~ very strong one, to which g~encr;d dcscrip-
<br />il~ ~~~, as above decailerl, applies. • It is of varying width, iu places narrowing to a couple of feet,
<br />ur ~,,ussibly less, then opening' Co such width as special investigation only could delcnniuc. 1C
