ON THE ROAD TO THE MILPILLAS MINE LOCATION The Milpillas Copper Mine, also known as La Parreña Mine, is located in the Santa Cruz Municipality of Sonora. Sonora is a large state located in northwestern Mexico. It borders the U.S. states of Arizona and New Mexico to the north, the Mexican states of Baja California to the west, Chihuahua to the east, and Sinaloa to the south. Its western edge lies along the Gulf of California (Sea of Cortez). Much of the state is covered by the Sonoran Desert. The Milpillas Copper Mine is located approximately 40 kilometers (25 miles) south of the US-Mexico border, positioning it as an integral part of a larger, cross-border mining region deeply connected to Arizona’s long-standing mining industry. Specifically, it lies about 60 kilometers (37 miles) southwest of Bisbee, Arizona, a town renowned for its Copper mining history. Tucson, a significant city in Southern Arizona, is roughly 188 kilometers (117 miles) to the north-northwest. Closer to home, the Milpillas mine is situated about 20 kilometers northwest of Cananea, a significant Mexican mining center with a population of 30,000. Cananea’s economy heavily relies on the large Buena Vista del Cobre mine. The closest settlement to the Milpillas Mine (La Parreña) is the small village of Milpillas, with just over 170 residents. Other nearby communities, such as Cuitaca and Vicente Guerrero, underscore the area’s rural and mining-focused character. Access to the Milpillas site from Cananea involves navigating a mix of paved, secondary, and unpaved mining roads. BRIEF HISTORY The Milpillas Mine in Sonora, Mexico, discovered in 1978, faced an uphill battle for development. For decades, it lay dormant, hampered by low Copper prices and significant geological hurdles, most notably being buried beneath 250 meters of water-saturated alluvium. However, extensive exploration efforts by Minera Cuicuilco and Industrias Peñoles between the 1980s and 2001 ultimately confirmed substantial high-grade Copper reserves. Underground mining operations for Copper finally began in 2006. Milpillas quickly gained fame not just for its Copper, but also for its world-class mineral specimens, particularly the striking "electric blue" Azurite crystals, Malachite, and Cuprite found in its supergene enrichment zones. Despite its geological riches, operations were indefinitely suspended in 2020 due to high costs and falling Copper prices. Fortunately, mining activities resumed in June 2022 and are ongoing. Geological Setting and Mineralization The Milpillas mine is discreetly situated within the Cuitaca Graben, a prominent north-south trending extensional basin within Sonora’s Basin and Range province. The valuable Copper deposit was initially concealed beneath younger layers of Tertiary gravels and Quaternary alluvium. The underlying geology primarily consists of volcaniclastic rocks from the Laramide Mesa Formation and older Jurassic Henrietta Formation, which have been intruded by monzonitic to quartz monzonitic porphyry stocks. High-grade supergene enrichment, a process that generated the mine’s renowned Azurite, Malachite, and other secondary Copper minerals, occurred within these host rocks at depths ranging from 150 to 750 meters below the surface. Climate, Flora, and Fauna Milpillas experiences Sonora’s characteristic arid to semi-arid climate, set within a Basin and Range topography of alternating mountain ranges and expansive valleys. While higher elevations near Cananea support scattered pine-oak forests, Milpillas’ immediate vicinity is a typical desert environment at lower elevations. The flora is well-adapted to drought, including various cacti (such as nopal and barrel cactus), mesquite trees, creosote bush, and resilient desert grasses and shrubs. The fauna, equally suited to these conditions, includes coyotes, diverse rodents, and numerous reptile species, such as snakes and lizards. (Author: silvia)

Once on the glacier (Mer de Glace) it is several kilometres walk to some more ladders, to get off the glacier and up the path to the Courvercle Hut below the Aiguille du Moine. The glacier is ’dry’ this low down at this time of year so is mostly easy to walk on - you can see the objective dangers (crevasses) and avoid them. A refreshing cold breeze blows down the valley, otherwise it would be hot under the summer sun. Photo scanned from slide. (Author: Mike Wood)

Opal Queensland, Australia 15 x 6.3 x 5 cm ex-Bill Rudner. Way back when, a person could stop by Chris Wright’s place in Hot Springs and go through a bin with boulder opal rough. It was sold by the pound. That was okay because about 99.99% of it was ironstone matrix. I suspect that possibly as many as a dozen people have high-graded it before it got to the bin but every now and again Chris would put back a piece for that special person. Unfortunately, more often than not, I was usually not that person. (Author: Don Lum)
