Emlyn Colliery, Penygroes. 
The Emlyn colliery consisted of two sets of drifts; the first was developed in the late 1880's by the Emlyn Colliery Co. Ltd.
Situated close to the head of the Gwendraeth Fawr at the village of Penygroes, it was separated from the Caerbryn mine underground by the Hendre fault.
Emlyn worked the Big Vein, Green, Stanllyd, Pumpquart and Trichwart.
By 1896 the mine employed nearly 450 men, which rose to 700 by 1913.
Later it came under the ownership of Emlyn Anthracite Colliery Co. Ltd., who employed 602 men here in 1918.
From a list 1923, there were 760 men employed, producing from the Stanllyd, Triquart Upper and Lower Pumpquart, and Lower Triquart.
In 1926 the mine had a lodge of the South Wales Miners Federation (forerunner of the National Union of Mineworkers) also in this year the second of the drifts started production.
In 1934 there was a 9 week strike over the minimum wage, which was settled in favour of the men.
The mine had a washery and was connected to the Mynydd Mawr railway line at Crosshands via tramway.
The mine closed in March 1939 with most of the men going to the nearby Crosshands colliery
