Field Activity Log: July 31 – August 9

This document is a daily log of field operations conducted from July 31 to August 9. The work involved a team consisting of two regular personnel plus eleven or ten additional specialists from Boliden. The primary activities focused on technical surveying and testing. On July 31, the team extended a raft to 10 meters in length and conducted comparative tests with various electrical apparatuses, surveying an area of 200 x 20 meters. On August 1, they continued with raft construction for measuring bottom resistance (earth resistance) and surveyed an area of approximately 50 x 200 meters north of line 1050. On August 2, the team performed a search using ore-prospecting equipment and measured resistance at the bottom near the impact point; this day also included an inspection by Colonel Dahlgren. Operations continued through August 5, involving fine-tuning measurements and data processing, followed by the team's departure from Boden. From August 6 to August 9, the work focused on further raft modifications for bottom resistance measurements and conducting soundings at locations where the ore-prospecting equipment had previously indicated results.
