Stateline Property

Exploring in the Lisbon Mining Complex in Colorado

The Stateline Property

The Stateline Property is a copper-silver project located in  San Miguel County, Colorado, USA, straddling the border with Utah.

It is comprised of 22 unpatented mining claims. 


The Stateline Property is located 10 km Southeast of the Lisbon Valley Mining Complex, 30 km southwest of Naturita, Colorado and 70 km southeast of Moab, Utah.  The property consists of 22 unpatented mining claims. 

The property is 148 ha and road accessible. Stateline has favourable stratigraphy for sediment hosted copper deposits in the emerging Paradox Copper Belt. It is located in the Lisbon Valley along trend of the Flying Diamond copper deposit.


Copper mineralization has been recognized in the Lisbon Valley since the 1890’s. Early modern exploration programs done by Noranda (1970’s) and Kennecott (1990’s) focused on bulk-tonnage deposits, although it is now apparent that a lack of understanding of the stratigraphy impeded many of these efforts. More recent work by Constellation Copper Corp. and, later Lisbon Valley Mining Company (LVMC), identified a series of near-surface deposits in the Lower Lisbon Valley. Regional programs as part of this work included sampling over the Stateline claims and is highlighted by results of 1.6% Cu and 1.7 g/t Ag from rock sample, and 0.47% Cu and 2.1 g/t Ag across a 12 ft chip sample.


Lower Lisbon Valley is the collapsed crest of a salt-cored anticline, bounded to the SW and NE by normal faults. The Stateline property is located along the NE bounding fault of the collapse structure. Outcropping formations on the property include sandstone belonging to the Dakota and Burro Canyon Fms., currently the productive mining horizons in the South Lisbon District.

Copper is spatially associated with bleached and altered zones adjacent to the faults. Mineralization in outcrop includes malachite, azurite, chalcocite and black copper oxides. Mineralization may be amenable to modern open pit mining with Solvent Extraction Electrowinning (“SXEW”) processing similar to the Lisbon Valley Mine. The mineralization noted to date is interpreted to be the southeast extension the Flying Diamond mineralization.
