Index Bornite mine located on Lewis Creek in Snohomish County of the Index Mining District.

The Index Bornite mine was discovered on May 20th 1898 by Alec Watt, Chas E. Cummings, and York Barington.  There were two claims associated with this mine, Barry and Hillside.

The development work of this mine consisted of 700 feet of tunnel and cabins.  The Barry claim also consisted of a 70 foot shaft on the vein. 

The main tunnel contained a vein four inches wide filled with pure bornite.

According to the Financial Times of 1905, assays from this mine were from 16 to 50% copper and 6 to 8 oz. of silver per ton.  The claims were incorporated as the Index Bornite Copper Company 1902 - 1917.
