Southwestern Prospectors & Miners Association: Located in Congress, Arizona — Not La Mesa, California

The Southwestern Prospectors & Miners Association (SPMA) is not in La Mesa, California. Its headquarters and primary operations are in Congress, Arizona—a historic gold mining town in Yavapai County, ~80 miles northwest of Phoenix.

Why the Confusion with La Mesa?

• La Mesa (San Diego County) has no major prospecting organization.
• Possible confusion with San Diego Mineral & Gem Society (La Mesa adjacent) or Southern California Mining Association (different entity).
• SPMA is distinctly Arizona-based — focused on AZ claims, AZ regulations, AZ geology.

Visiting / Joining

• Website: swpma.org (check for current meeting schedule, claim maps, membership form)
• Email: info@swpma.org
• Best time to visit: Oct–Apr (summer >100°F). High-clearance vehicle recommended for claim access.
• Nearby attractions: Congress ghost town, Stanton (ghost town), Weaver Mountains, Wickenburg (historic mining supply town).

If you're a prospector in Southern California looking for community, check San Diego Mineral & Gem Society (El Cajon) or Orange County Mineral Society. But for Arizona gold country access and active claim programs, SPMA in Congress, AZ is the real deal—not La Mesa.
