About this location
Organ is a small community at the north end of the Organ Mountains in Doña Ana County, New Mexico, giving its name to the Organ Mining District, which produced copper, lead, silver, zinc, and gold worth about $2.5 million from discovery in 1849 through 1952. The range itself is quartz monzonite and rhyolite, with ore deposits in veins, fault zones, and replacement bodies in the surrounding sedimentary rock — worked historically by mines including the Torpedo, Modoc, Stevenson-Bennett, and Ben Nevis. The critical fact for this page: in 2014, most of the Organ Mountains became part of Organ Mountains-Desert Peaks National Monument, a nearly 500,000-acre BLM-managed monument. National monuments generally prohibit rock and mineral collecting, and this could not be confirmed either way for this specific monument in the time available — that makes current legal collecting status here a real open question, not a minor footnote.
Always seek permission where required, follow local laws, and practice Leave No Trace. Locations and details are community-submitted and may be inaccurate. Not sure what's legal here? Read our full guide to rockhounding laws by land type.
Found Here
Historic production from the Organ district includes copper, lead, silver, zinc, and gold, with ore as mixed sulfides in veins and replacement bodies. The DB also lists brochantite, cerargyrite, cerussite, chalcopyrite, molybdenite, chrysocolla, onyx, and rock crystal — plausible secondary and vein minerals for a copper-lead-silver district of this type, but not independently confirmed specimen-by-specimen against a mineralogical source in this research pass.
Difficulty
Getting there
Organ is a small community off US-70, northeast of Las Cruces, New Mexico, at the base of the Organ Mountains' north end (the "Needles"). BLM maintains public access points nearby at Aguirre Springs Campground, Baylor Canyon Road, Dripping Springs Natural Area, and Soledad Canyon.

UNVERIFIED and potentially not permitted — see the access note below before planning any collecting trip here.
Know before you go
This is the most important fact for this page: most of the Organ Mountains, including the historic mining district, now sit inside Organ Mountains-Desert Peaks National Monument, established by presidential proclamation in 2014 and managed by the BLM's Las Cruces District. National monuments as a rule commonly prohibit rock and mineral collecting regardless of managing agency, but the monument's specific rules on rockhounding could not be confirmed from the BLM's monument pages within this research pass. Do not publish or act on collecting directions for this site without a direct call to the BLM Las Cruces District Office (575-525-4300) to confirm current rules. Separately, the mountains' southern limestone section (Rattlesnake Ridge) is entirely within Fort Bliss and closed to the public outright.
