Comments on the production information

  • LESSEES PRODUCED ORE WITH GROSS VALUE OF $25,000 FROM 1904-1908. IN 1908, LESSEES ON THE HAZEL-GOLDFIELD LEASE OBTAINED $200-$300/TON ASSAYS AND WERE SHIPPING-SOME ORE. SOME HIGH-GRADE ORE FROM THE MUSHETT LEASE RAN $8000/TON

  • Type of workings Underground
    Overall depth 170.69M

Comments on the workings information

  • 560 FT SHAFT BY DEC, 1908, WITH LEVEL WORKINGS AT 130-FT, 275 FT, AND 350 FT. ALSO A 740-FT SHAFT ON THE HAZEL GOLDFIELD LEASE; A480-FT SHAFT ON THE MUSKETT LEASE-WITH SEVERAL LEVELS, AND A 420-FT SHAFT ON THE MOHAWK-RED TOP LEASE, ALL WITH MANY LEVEL WORKINGS AND STOPES. (FIVE FRIENDS LEASE)

Comments on development

  • LAGUNA GOLDFIELD MINING CO. WAS INCORPORATED IN 1906, LATER TAKEN OVER BY GOLDFIELD CONSOLIDATED MINES CO. LATE IN 1906. PROBABLY LITTLE OR NO PRODUCTION IN AND OF ITSELF. FIVEFRIENDS LEASE AND HAZEL-GOLDFIELD LEASE WERE OPERATING HERE IN 1908 ON THE LAGUNA AND LAST CHANCE CLAIM, AND THE MUSHETT LEASE AND MOHAWK-RED TOP LEASE WERE OPERATING ON THE MISS JESSIE CLAIM
