The Kingston Gold Mines.
The Kingston Gold Mines have acquired four important concessions in the municipality of Puente de Domingo, Florez, in the province of Léon. These properties are well situated on the banks of the river Sil and its tributaries, and are very accessible, being close to the railway station of Ponferada. The alluvial deposits cover almost the whole of the area of the concession. The average of the assays made of the alluvial deposits give five dwts. of gold per cubic yard; but the engineers state that, taking the average at only one and a-half dwts. per cubic yard, these properties ought to give a large return per annum.
