TRANSACTIONS OF THE SECTIONS. 89 
Ganllwyd Gold Mine has two very distinct lodes, from one of which he had taken 
several stones of visible gold. The poorest stuff contains on assay 10 to 11 dwts. 
of gold to the ton. This mine will probably prove a second Clogau, as the lode- 
stuff is identical in character with the Saint David’s Lode. 
Coed-cy-fair Mine is S.W. of Maesgwm, and has the same surface appearance. 
Visible gold has recently been found here. Assays haye given 3 to 5 dwts, to the 
ton from surface quartz. 
Tue BERTHWLLYD SECTION. 
Berthwllyd Mine is situate on the summit of the precipitous and lofty ridge of 
hills to the west of the curious little roadside inn, the “ Oakley Arms,” at Tyn-y- 
groes, on the Trawsfynydd road from Dolgelley. 
There is what Mr. Warington Smyth appropriately calls “that grand champion 
lode Berthwllyd,” which runs in a direction N.N.E. and 8.8. W. for about a mile. 
Blende and galena are the chief products of this mine, all of which are auriferous. 
Only a few days ago, the author saw both blende and galena pounded fine, and 
gold washed therefrom, in the proportion of 3 to 4 ounces to the ton. He himself 
washed gold from the alluvium of so fine a quality that it floated on water. 
As much as 6 ounces to the ton has recently been extracted by Britten’s amal- 
amating-machine. This mine is destined to produce, he thinks, from its inex- 
haustible supply of metalliferous quartz, some extraordinary results. 
Goitref Mine adjoins the last, the quartzose lodes of which are auriferous. 
Caegwernog Mine adjoins Berthwllyd, and is favoured with a continuation of the 
Great Champion Lode at Berthwllyd. Trials of ores from this mine have produced 
sometimes as much as 8 ounces to the ton. A few days ago, the author visited the 
spot for the first time, and discovered an old heap of calcined stuff upon which 
were visible globules of gold. Assays of the surface lode-stuff produced from 2 to 
4 dwts. to the ton. 
Cae Mawr Mine adjoins the Berthwllyd and Caegwernog Mines. It was here 
that the first gold was discovered. Visible gold has recently been found. Assays 
give from 9 to 11 dwts. to the ton of surface mineral. 
Gold is also found in the alluvium, by washing, in about the same proportions 
as at North and West Dolfrwynog. 
Benrhos Mine.—The alluvium here contains specks of goid, similar to the last- 
mentioned. 
Tyny-benrhos Mine adjoins the last, and contains gold in the alluvium, as above. 
Glasdir Copper Mine, to the N.I. of Tyny-benrhos, is a very remarkable pro- 
perty ; £15,000 worth of copper-ore has been sold from this place, simply the result 
of quarrying. Very rich gold-stones have been found here, some of which the 
author had seen. 
THE CAMBRIAN SECTION. 
This section extends along the north side of the turnpike-road from Dolgelley 
to Barmouth. 
The Cambrian Gold Mine has six remarkable blende lcdes, three of which the 
author knows to be highly auriferous. No. 6 lede produces gold occasionally 
very rich in blende. He had himself extracted gold from the blende-ore, at the 
rate of 300 ounces to the ton. There can be no question about gold being found 
here in paying quantities. Very rich ore has been recently raised. One large spe- 
cimen contained gold in the slate. A very rich specimen was exhibited. 
The Cuwmabseifian (East Clogan) Mine is situate to the north of the Cambrian 
Mine. The noticeable lode in this sett is one that has the appearance of being a 
continuation of the Saint David’s Lede at Clogau. The quartz is similar, and con- 
tains gold on assay. Mr. Clement’s analysis gives 18 dwts. 14 gys. to the ton. 
The Princess Alice Mine, situate between the Cambrian and the Prince of Wales 
Mines, has given gold on assay at the rate of 8 dwts. to the ton. The lode-stuff 
has the same character as the Cambrian. The author extracted gold from it in 
1856. 
Moel Ispri Mine, on the N.E. of the last, has yielded, it is said, at the rate of 
8 ounces of gold to the ton of galena. 
The Prince of Wales Mine is on the east of the Princess Alice. It has several
