His 1923 work, Gold placers of California (California State Mining Bureau Bulletin 92, 1923) described all economic occurrences of alluvial gold deposits in California that were known at the time. Bulletin 92 was the first statewide comprehensive study of tertiary fluvial placers, dredge fields, and dry placers. Even present-day, it continues to be a standard reference.
His early mining experiences were in Alaska, California, and Oregon, as well as Colombia, Honduras, and Peru.
In 1921, upon returning from an assignment in British Columbia, Haley was retained by the California State Mining Bureau to document California"s gold placers. After conducting the study, he authored Gold placers of California: California State Mining Bureau Bulletin 92 and Topographic map of Sierra Nevada gold belt showing distribution of the auriferous gravels, in 1923.
One of his articles also appeared in the journal, Mining and Scientific Press.
