Located on the surface of the Maginnis are approximately 20,000 tons of historic dumps and tailings containing 1,500 ounces of gold and 25,000 ounces of silver. A 5-ton stockpile of 2.32 opt Au and 2.64 opt Ag ore is also present. While the gross value of these dumps and stockpile is relatively small, it could provide the opportunity to conduct metallurgical testing and at the same time provide some production.

The most recent ore reserves and resources were presented in a 1992 report by Viking Exploration, Inc. which represents the potential of the Gold Hill properties (silver reserves were not included). There are Measured Reserves of 4,400 ounces of gold at a grade of .49 opt Au in the Spotted Horse/Kentucky Favorite. Indicated Reserves of 10,900 ounce of gold at a grade of 0.53 opt Au in the Spotted Horse/Kentucky Favorite and a small portion of the Maginnis and Cumberland . Inferred Reserves of 112,100 ounces of gold at a grade of 0.44 opt Au. Speculative Resources are 311,000 ounces of gold at a grade of 0.41. Measured reserves are defined as those within 100 feet from known ore shoots. Indicated are those within 100 and 200 feet of known shoots. Inferred Reserves are defined as those located within 200 to 300 feet of known ore shoots, and between the three mines along the Gold Hill contact. Speculative Resources are defined as those between 300 to 400 feet of known ore shoots, along the Gold Hill contact and breccia pipes.
