The video is a record of a successful lake tap blast from our Upper Ramona project. The blast was 32m under the lake surface and at the end of a 65m long lake tap tunnel. The blast connected the lake to the 1800m of rock excavation we completed which included a 528m long Alimak raise. Note the delay after the blast button is pressed, the Ikon system doing a final cap check before firing, the suspense of these long seconds turned to relief as we heard the caps fire.
