Lumsden Mine is a late 1800s copper-zinc deposit with historical best assays of gold, silver, copper, and zinc as follows:

• Goodwin (1928), 5.14g/t Au, 32.57g/t Ag, 1.2% Cu, and 12.77% Zn
• Channel sample (8.7 m) of discovery trench reported by Flaherty, G. (1933 PhD Thesis, MIT, p. 347) with assay of 6.5 g/t Au, and 8.6 g/t Ag
• CCH Minerals Ltd., 1981 reported multiple samples with ore grade values up to 4.3% Cu and 9.2% Zn (Figure 1)
• D. Rose (DNR staff), 1989 sample #056-1 with 18 g/t Ag, 3.4% Cu, and 14.1% Zn
• Adit No. 1 with gold gram equivalents (samples 1-5) contained 3.2 g/t, 6.4 g/t, 9.6 g/t, 6.4 g/t, and 3.2 g/t Au consecutively. This represents an 8.77 m wide zone of continuous gold
• Drill hole No. 3 in an area outside the main mineralized lens contained a 2.5 m section of 0.47% Cu and 3.00% Zn

The historical data suggests that there is consistent distribution of zinc, gold, and copper values over a significant distance, which is worthy of follow up not only within the known zone, but also along strike. The main mineralized zone is being crosscut by a fault with displacement of the eastern section to the north. The historical trenching concentrated on the western section of the mineralized zone demonstrating good zinc values of approximately 3% to a high of 18% and contained background to significant gold values as well.

Report of work 473890 (J.A. Roy McIntyre, Rat Tail Brook property, 1990) lists some of the historical gold values in oz/t units (Figure 2). When converting these to g/t units, the five channel samples collected in the tunnel range from 3.2 g/t to 9.6 g/t Au. The report does not identify the exact location of these samples; however, the channel samples appear to be referring to the Adit No.1 samples listed on Plate 46-27B (1947) because the number and width of the five samples correspond (Figure 3).
