Haranga Resources (ASX:HAR) completed diamond drilling at the Cross Cut 3 at the Lincoln gold project in California, with four holes drilled for a total of 334.4 meters, while drilling at the Cross Cut 4 is nearing completion, with the final drill hole currently being drilled, according to a Tuesday Australian bourse filing.

Dewatering activities were temporarily constrained by rain, resulting in a short-term rise in underground water levels over the Christmas period. The Cross Cut 5, the next cross-cut in the planned program, is currently being drained, with access expected to be re-established in the coming days.

The firm's shares fell 8% in recent trading on Tuesday.
