197 Development One tunnel, 295 feet long, at the level of the lowest exposure, a 10-foot shaft, about a dozen open-cuts, strippings, and trenches showing magnetite, and many others that do not, constitute the entire development of the deposit. The tunnel level exposes magnetite at a depth of 120 feet below the highest surface exposure. From a mining standpoint the deposit. is handicapped by being located so close to sea-level as to prohibit much development by tunnelling methods. Analyses There are many analyses available in private reports and published literature, and these are here quoted for what they are worth. Most of them are taken from the bluff of magnetite at the west end or from the magnetite within the tunnel. It is reasonable to expect that surface leaching may have removed sulphur from this part of the deposit, making the analyses quoted lower in sulphur than the average for the deposit. No sampling was undertaken by the writer. — A B Cc D E ¥ G H di K Tron.........|64-3 59-82 | 57-60 | 57-84] 60-50] 60-12] 60-89 63-7 63-8 52-4 InAs) M1) Coal OX) llbaaooscolloodgoasel boocnsceldosnoocalbneseses Sofa Gos ongoalldonanbae|otpodads mUlveaae cession nee 5-59 6-00 6-70 2-94 3°40!) eee 3-85 4.2 4-6 Sulphur.....]...... 1-68 4-85 2-41 0-44 0-10 0-76 0:3 0-55 0-2 Phosphorus.| 0-009} 0-024 0-023) 0-013} 0-006] 0-016] 0-004/Trace |Trace |Trace Manganese..|......

Rept., Minister of Mines, 1922, p. 226, average sample from shipment of 10 tons. These nine samples, taken by five different engineers, from different parts of the deposit, reveal a remarkably uniform grade and a very high desirable tenor of ore. It is safe to say that the Sarita deposit as a whole contains, as far as present exploration goes, the highest grade of magnetite encountered along the west coast of Vancouver island. PSHORSYO ¥ Tonnage Estimate Lack of information concerning the structure of this deposit renders futile any attempt at tonnage estimates. However, one might conservat- ively say that about 30,000 tons of probable ore occurs in the bluff near the portal of the tunnel, but this quantity would be of much lower grade than the analyses quoted above. Of this amount, about 5,000 tons may be con- sidered as positive or proved ore. Approximately 400 tons of magnetite are in the two ore piles, which would increase the positive ore tonnage to 5,400. : No estimate of possible ore could be made without a knowledge of the structural geology of the deposit.
