Hello - I saw this posting and looked up Dines for information, and the following I have copied over for you, as it seems that you do not have a copy of Dines. Hope you can understand the follwing: -
Unity Wood or West Poldice: - Âľ mile N. by W. of St. Day. 1-in. geol, 352; 6-in. Corn. 56 S.E., 57 S.W., 63 N.E., 64 N.W. Also known as Tolgullow United (A.M.R 16 A and 2343). Country: metamorphosed killas overlaying the north-eastern flank of the Carn Marth granite, traversed by elvan dykes.
Several lodes were worked in Unity Wood, in the north of the sett, from the crosscut south at from Skip Shaft on Middle Lode of Killifreth Mine and from Oate’s Shaft and Blamey’s Shaft, respectively at 310 yds. and 400 yds. S. of Skip Shaft. At 10 fms. N. of Oate’s Shaft the crosscut intersects Pits-an-Voller Lode, coursing E. 12° N. and underlying 40° S.
MacAlister (in Hill and MacAlister 1906, p. 248) states that the underlie is 16° to 30° N. from the 30-fm. To 80-fm. Level, but the plan shows no drives below the 36-fm. Level. Adit Level extends for 180 fms. W. and the 36-fm. Level for 140 fms. W of the Shaft. Coursing N.E. and underlying 45° N.W., another lode intersects the above near Oate’s Shaft and has been opened up for 120 fms. S.W. of the shaft at adit and the 20-fm. Level, and for a short distance at the 36-fm. Level. There is another shaft on this lode, Trestrail’s, at 200 yds. S.W. of Oate’s Shaft. A third lode, coursing N. 30° E. and underlying steeply north-westard, had been developed at the 9-fm., 18-fm. and 26-fm. levels (below surface) for 45 fms. S.W. and 20 fms. N.E. of Blamey’s Shaft.
A crosscut 110 fms. S. at the 36-fm. level from Oate’s Shaft, passes just west of the position of Blamey’s Shaft at 45 fms. S. and ends at Trefusis Lode, which is the most important lode in the sett. Coursing E. 35° N. and underlting 20° N.W., it has been opened up from Broad’s Shaft or Tolgullow Shaft, 300 yds. N.E. of Tolgullow hamlet, vertical to Shallow Adit (18 fms.) and on the underlie to the 60-fm. level; Paul’s Shaft, 210 yds. N.E. by E. of Broad’s, vertical to Middle Adit (33 fms.) and on the underlie to the 80-fm. level; Painter’s or Henderson’s Shaft, 190 yds. N.E. by N. of Paul’s, vertical to Deep Adit (33 fms. Here but 40 fms. At Broad’s Shaft) and on the underlie to the 50-fm. level; Trefusis Shaft, 85 yds. N.E. by N. of Paul’s, vertical to the 36-fm. level and on the underlie to the 100-fm. level, and Magor’s Shaft, 210 yds. N.E. of Trefusis, on the underlie to the 100-fm. level. Two shafts, Harper’s and Sandow’s or Symon’s, respectively 210 yds. N.E. and 280 yds N.E. of Magor’s, are on the line of the strike of the lode, but workings from these are not shown on the plan. Shallow Adit Level is driven for 130 fms. S.W. from Broad’s Shaft, Middle Adit Level for 140 fms. S.W., and Deep Adit Level extends from 120 fms. S.W. of Broad’s Shaft to Trefusis Shaft, a distance of 335 fms. Levels from the 10-fm to the 40-fm. block out the lode from 70 fms. S.W. of Broad’s Shaft to 45 fms. N.E. of Magor’s, a distance of 420 fms.; the 50-fm and 70- fms. levels (the latter is labelled 65-fm. between Broad’s and Trefusis shafts) extend from 15 fms. S.W. of Broad’s Shaft to 45 fms. N.E. of Magor’s Shaft; the 80-fm. level is driven from beneath Broad’s Shaft to 80 fms. N.E. of Magor’s Shaft; the 90-fm. and 100- fm. levels are both in two parts, the former level extending 130 fms. S.E. of Trefusis Shaft and 15 fms. Each way from Magor’s, and the latter for 20-fms. S.W. of Trefusis Shaft and 10 fms. S.W. of Magor’s.
Stoping is in two areas; on the west, from above Shallow Adit to the 65-fm. level it extends 100 fms. S.W. and 70 fms. N.E. of Broad’s Shaft, and on the east, from above Deep Adit Level (26 fms. At Trefusis Shaft) to the 60-fm level, extends 50 fms. S.W. and 100 fms. N.E. of Trefusis Shaft; there is also a small stope on the 65-fm. and 80- fm. levels just east of Paul’s Shaft; about 20 per cent of the blocked-out ground has been removed. Though the general strike of the lode is E. 35° N., at 20 fms. N.E. of Broad’s Shaft there is a change of strike to due east for about 45 fms., after which the normal strike is resumed. The longitudinal section shows an elvan **** crossing the lode at the 40-fm., 50-fm. and 65-fm levels at about 25 fms. N.E. of Broad’s Shaft, which may be the cause of the change of strike. A crosscourse, trending N.-S. and underlying 30° E., intersects the lode at the 20-fm level N.E. of Paul’s Shaft on Deep Adit Level and 50 fms S.W. of Trefusis Shaft on the 90-fm. level. The granite-killas contact, sloping very gently north-eastwards, is intersected by Broad’s Shaft just above the 50-fm. level; stopes extend about 10 fms. Below the surface of the granite 30 fms. E. of the shaft. A crosscut 35 fms. S. from Deep Adit Level at 20 fms. E. of Broad’s Shaft, meets Simon’s Shaft, and a crosscut 80 fms. N. by W. from the 80-fm. level at Trefusis Shaft meets Jeffrey’s Shaft.
Henwood (1843, Table lxvi) refers to two tin-impregnated elvan dykes called Great Elvan Lode and Trestrail’s Elvan, but these are not indicated on the plan. The former up to 4 fms. Wide contained cassiterite crystals sprinkled through it, and the latter, 1 ft. to 2 fms. Wide consist of fine-grained schorl rock that yielded large quantities of tin ore from above the slide.
Records of output are as follows: - Unity Wood: 1815-36, 1838 and since 1852, 21,620 tons of 6 per cent copper ore, 570 tons of black tin, 129 tons of arsenic, 21 tons of pyrite, and 1½ tons of lead ore. According to Phillips and Darlington (1857, p. 264) 32,756 tons of 7½ per cent copper ore were raised between 1223 and 1842. West Poldice: 1832-6, 1874-84, 1,152 tons of 7 per cent copper ore; 1837 and since 1851, 650 tons of black tin. Tolgullow United: 1882 to 1903, 570 tons of black tin, 20 tons of 15 per cent copper ore, 222 tons of arsenic, 152 tons of mispickel and 185 tons of ochre.
