1: Carwinning Hill is mentioned in the Special Reports on the
Mineral Resources of Great Britain Vol. XVII - The Lead, Zinc, Copper
and Nickel Ores of Scotland - 1921 (as republished by Richard Bird in
the 1980's), Page 129
"Swinlees Mine, Ayrshire (Abandoned). The old mine is situated
on the south slope of Carwinning Hill, about half a mile W.N.W. from
Swinlees House and two miles north of Dalry. The mine was worked nearly
a century ago (from 1921), and was abandoned owing to lack of ore. The
vein trends north-west, and is from 2 to 3 feet in width. The infilling
consists mainly of broken country-rock (intrusive felsite, and
limestone), calcite, quartz and barytes, with associated chalcopyrite
and malachite. Two levels have been driven along the vein, but the lower
one is now closed; from the size of the dumps, a fair amount of work has
been carried on."
2: Bryn Gwiog Mine is mentioned in the Special Reports on the
Mineral Resources of Great Britain Vol. XIX - The Lead and Zinc Ores in
the Carboniferous Rocks of North Wales - 1921 (as republished by Richard
Bird in the 1980's), on pages 6, 11, 14, 16, 21, 24-5, 28, 71, 73, 75,
127-8, 131 and 148. It is slap in the centre of the Halkyn mining field.
The Mines of Flintshire and Denbighshire (The Mineral
Statistics) as published by Exeter, gives production figures etc, and
states that the mine was owned by Bryngwiog Mines Limited from 1906 to
1911, but was suspended from 1908 to 1911. Map reference is SJ192691.
3: Graigwen Mine. I can find no reference to Graigwen, but there
are two Craigwen and one East Craigwen Mines listed in British Mining
No. 6 - The Mines of Merioneth.
"Craigwen Mine, Llanaber Parish SH655190. This mine was worked
for gold and probably some copper ores on veins striking ENE in Cambrian
rocks. These veins may be a continuation of those worked at the St.
David's Mines. The chief filling is massive quartz in which pyrite,
chalcopyrite, galena and sphalerite occur. The earlier trials here were
carried out in 1854, when the mine was worked on a small scale. In 1862,
it was reopened under the name of West Clogau Mine, and was later worked
as a part of the St. David's Mines. At this time Bwlch Coch was also
included in the sett. In 1863, the operating company also worked for
alluvial gold in the Afon Mawddach, but apparently without very much
success. (Refs. Mining Journal)."
"Craigwen Mine (also known as Pennant and Craigwen), Mallwyd
Parish SH836174. This mine seems to have been worked in conjunction with
Pennant Mine at times, hence the combined title. Craigwen Mine itself
was worked on Silver-Lead Vein, striking NW, and Benjamin's Vein,
striking about E and W, both occurring in sedimentary and intrusive
rocks of Ordovician age. The chief vein mineral is quartz, but calcite
is fairly common and a certain amount of barite occurs in lenses and
pockets. Much pyrite is found in the veins, associated with galena,
sphalerite and chalcopyrite. The mine was worked through three main
levels, driven into the mountain-side and there are sump workings to a
depth of about 60 feet below the lowest adit level. Mineralisation
appears to be somewhat patchy and weak, and the only output figures seen
refer to 12 tons of lead ore concentrate, sold in 1851. The mine was
active in 1848, and continued in operation until 1852. It was again at
work between 1853 and 1855, but little or nothing seems to have been
done since that time. (Refs. Mining Journal 1848 to 1855, fairly
numerous reports at times)."
"East Craigwen Mine, Llanymawddwy Parish SH844184. Trials were
made here on veins which occur between those of Cowarch Mine and those
of Craigwen Mine. The veins are found in rocks of Ordovician age. The
trials were made in 1850, but in spite of glowing reports issued at that
time in order to attract capital to the scheme, little or nothing of
importance seems to have been found and no working mine seems to have
been developed here. (Refs. Mining Journal 1850)."
There is also a Craigwen Mine listed in The Mines of Flintshire
and Denbighshire (The Mineral Statistics) as published by Exeter. It is
situated in Llanrwst, Caernarvonshire at SH836174 (The same as the
Craigwen Mine in Mallwyd Parish). It gives a production of 12 tons of
lead ore in 1851.
4: Creigiog Mining Co. The following paragraph is in the Special
Reports on the Mineral Resources of Great Britain Vol. XIX - The Lead
and Zinc Ores in the Carboniferous Rocks of North Wales - 1921 (as
republished by Richard Bird in the 1980's), page 101. It occurs in a
section entitled Maes-y-Safn to Llandegla.
"A fault-vein with spar, occurring south of the Maes-y-pwll
Lode, runs from Creigiog-isaf in a south-easterly direction. Its course
is shifted to the south by an oblique fault south-west of Alltgymbyd,
after which it resumes its original course, and is accompanied by a
parallel fault about 100 yards to the south. The outcrops of the veins
are marked by old shafts and open-cast workings for lead, which seem to
have been moderately successful."
The Mines of Flintshire and Denbighshire (The Mineral
Statistics) as published by Exeter, gives the following
Creigiog Llanarmon SJ204559
Production Lead and Silver 5 tons of ore 1884
Zinc 2 tons of ore 1884
Ownership 1883-1887 Creigiog Mining Co. Ltd.
Comment 1883-1885 Formerly Bodidris
1886-1887 Formerly Bodidris: Suspended
Management Chief Agent 1883-1886 H. Hotchkiss
Employment 1883 24 U/G 6 Surf 30 Total
1884 14 U/G 6 Surf 20 Total
1885 8 U/G 3 Surf 11 Total
Hope this helps. I enjoyed putting this together.
