No systematic mining or quarrying has been attempted on these tin deposits. The 

 work has been carried on mainly by agricultural laborers and women and children. 

 The ore occurs in a strata cf soil, clay, decomposed shale, sand and pebbles. The 

 soft character of this tin ground would admit of cheap working, the only essential 

 dressing machinery being perhaps wasliing and sizing trommels and automatic jigs. 

 There can be no doubt that these tin deposits would pay to work on a considerable 

 scale.

At Martinamor veins are in gneiss, at other places they are in Silurian slates, more 

 or less dark, gi-ay, greenish, brown, blue. Veins are principally quartz, carrying 

 tourmaline, wolframite, some arsenopyrite and copper sulphide. Veins running in 

 different directions are without noticeable difference in mineralization. Some greisen 

 dikes carry up to 9 per cent tin. One vein at Tcrubias gave 25 kilos per cubic 

 metre of 40 per cent tin ore. This vein is 1600 metres long. Some 60 per cent ore 

 was obtained.
