Figure 3. Outline of the detailed, ground-based gravity survey completed in March, 2021, at Hecla Kilmer. It is roughly 1.5 x 3.5 km’s in size. The main block of the gravity survey comprises 573 stations on an equant, 100 metre grid spacing. It was designed to cover the main RTP magnetic boundaries and anomalies delineated by a high resolution airborne survey completed in the region in 1993 and shown here as the base map for the large and concentrically zoned, multi-phase carbonatite complex roughly 4 x 6 km’s in size at H-K.
