Speaker: John C. Lacy, author and historian

Talk Summary:
The first adventurers into the New World faced a fundamental legal challenge: how to secure rights to any mineral claims they discovered. Early conquistadors worked under charters that required them to return a portion of their findings to the Spanish crown, but those without such charters had no formal protection, and the crown was slow to clarify individual rights. This uncertainty only grew as miners pushed into the lands that would become the Western United States.
When gold was discovered in California, miners suddenly found themselves operating without any governing laws during the period between the end of the war with Mexico and the establishment of formal U.S. jurisdiction. In response, and without official sanction, they formed self-governing “mining districts,” best understood as mutual protection societies. These districts marked the first organized attempt to define boundaries and create rules for establishing and maintaining mining claims. As the early rushes in California and Nevada subsided, miners carried these practices with them into Arizona and other western territories.
In Arizona, no comprehensive collection of these early regulations has ever existed. The Law of the Miner addresses this gap by tracing the development of mineral law in early Arizona and presenting the full text of every mining district regulation found. This work serves both the mining industry and historians seeking to identify the individuals involved in creating the districts and to understand these districts’ historical boundaries.

Speaker Bio: John C. Lacy is a mining lawyer and mining law historian who has, throughout his career, analyzed and written about the contributions of mineral adventurers to the development of the law as it was applied to the acquisition of mineral rights. He graduated from the University of Arizona with a degree in journalism in 1964 and one in law in 1967. Lacy has represented mineral clients throughout the western United States and in South America and has taught mineral law and related subjects at the University of Arizona since 1976. His historical activities include work with the Arizona Historical Society, the Arizona History Convention, and the Society of Mining Law Antiquarians.

The subject of The Law of the Miner came naturally to Lacy as he grew up in the Peruvian mining camp of La Oroya, and during college, he worked as a fieldhand for several mining exploration companies. Presently, he is the director of the Global Mining Law Center at the James E. Rogers College of Law at the University of Arizona, where he teaches and supervises several online courses. He also continues to practice law at his firm, DeConcini McDonald Yetwin & Lacy, P.C.
