Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Deposit): 5-16-97: Hecla Approved Plans To Double Ag Output. The Expansion Wll Be Fuelled By The Development Of The Gold Hunter Vein (1500 M NW Of The Lucky Friday Vein). The Gold Hunter Vein Is Nearly Twice The Grade And Width Of The Lucky Friday Vein And Will Allow The Company To Increase Ag Production To Over 4 Moz By 1998. In 1996, The Operation Produced 1.9 Moz. The New Vein Will Be Mined Using Overhand Cut-And-Fill. In Addition, Hecla Plans To Upgrade Its Backfill Plant And Expand Its Concentrate Storage Facilities. Total Proven And Probable Ag Reserves At The Lucky Friday Mine Are 18.5 Moz. Property Includes The Golden Hunter Mine (Past Producer) Mas Seq# 0160790063.
Comment (Reserve-Resource): 86 Brook-Hunt & Ilzsg Data. Hecla 1989 10k Has 458,800 St At 16.1 Oz Ag, 14.4% Pb, And 2.4% Zn.
Comment (Reserve-Resource): 1996: Measured Grades: Ag=401 G/Mt; Pb=11.6%; Zn=1.8%. 1996: Indicated Grades (From New Area): Ag=290 G/Mt; Pb=4.1%; Zn=Not Given In The Phone Call (0? Or Unknown?) All Tonnage And Assay Values Are Based On Dry Tonnes Total Metal Recovery Is 105% Vs Reserves, Total Tonnage Recovered Is 130% Vs Reserve Reserve Tonnages Only Are Quoted In Hecla Published Figures. Grades Are Computed Back Through Metal Recovered And Recovery Factors. As The Recovery Of Cu And Au Are Unknown This Method Could Not Be Employed For These Commodities. They Were Therefore Carried Through At 100%.
