The Echo occurrence is located at about 1524 metres elevation, on the southwest flank of Idaho Peak and between Bartlett and Emily creeks.

Work began on the Echo occurrence in about 1914 and continued intermittently until 1926. Most the workings are close to the Echo-Alpha (Lot 562) claim boundary. Development was carried out in four adits. The uppermost adit was driven on the Link Fr. claim. The other three adits were driven northeast into Echo ground from the Alpha claim (082FNW180), crossing the claim boundary at about 61, 129 and 229 metres from their respective portals. The No. 3 adit is 30 metres vertically below the No. 4 adit and 76 metres vertically above the No. 2 adit.

Hostrocks of the Echo occurrence include argillite, calcareous argillite, limestone and quartzite of the Triassic Slocan Group. The general strike varies from north to northwest and dips vary from east to northeast at about 50 degrees.

Mineralization consists primarily of galena and sphalerite hosted in a strong fissure zone with considerable fault movement. Other minerals included tetrahedrite, pyrite and locally abundant chalcopyrite. Gangue minerals include calcite, quartz and siderite. Calcite is commonly coarsely crystalline forming bands up to 90 centimetres thick carrying brecciated fragments of galena, sphalerite and wallrock. The fissure zone is 8 to 21 metres wide and is composed of brecciated and faulted country rock hosting vein mineralization.

The adits explored the main Standard-Alpha lode which on the Echo-Alpha properties has a general strike of 060 degrees and dips about 45 degrees southeast. Several ore shoots were discovered and partially stoped from this fissure. One of these shoots was near the portal of the No. 3 adit and another on the Echo-Alpha claim boundary between the Nos. 2 and 3 levels.

Production records indicate 752 tonnes of ore was mined periodically between 1913 and 1928. This ore yielded 2,047,542 grams silver, 31 grams gold, 239,282 kilograms lead and 104,203 kilograms zinc.
