The Santa Rosa deposit has produced 150 000 oz Au since 2002 while the larger Cerro Tucari deposit is in the initial stage of mining, total production for 2004 being projected as 200 000 oz Au. Ongoing exploration is focused on three newly defined target areas. Atypical magmatic rocks in the district include rhyolitic dome complexes and typical igneous rocks are andesitic stratovolcanoes. The 700+ km2, NW-striking mining district is defined by hydrothermally altered volcanic rocks with at least five major hydrothermal centres. Deposit location is controlled by fault intersection. At Santa Rosa, gold is located along the margin of a rhyolitic dome and associated tuffs, and appears to have been introduced during events associated with crackle brecciation. Sulphides are mostly oxidised. Reserves are 5 000 000 t at 1.53 g/t Au. At Cerro Tucari, alteration was related to late-stage intrusion of dacites into a stratovolcano. Colluvial scree averaging 2 g/t Au gave an initial body of broken rock containing 150 000 oz Au and resources are around 50 000 000 t at 1.0 g/t Au., The Santa Rosa deposit has produced 150 000 oz Au since 2002 while the larger Cerro Tucari deposit is in the initial stage of mining, total production for 2004 being projected as 200 000 oz Au.

The hydrothermal deposits are hosted by moderately to strongly folded Lower Cretaceous distal sandstones and are Middle to Late Miocene in age. Their total gold potential may rival that of the volcanic-hosted, bulk-mineable deposits. Structural and stratigraphic controls are similar to those of Carlin-type deposits of the western USA. Ore-forming solutions generally ascended and deposited gold along steeply dipping zones of shearing and tectonic/hydrothermal brecciation as well as along pebble and breccia dykes and at the contacts between sedimentary and intrusive igneous rocks. Solutions also moved laterally from the feeders along favourable sedimentary units to produce manto ores of replacement origin. Gold at the Santa Rosa mine occurs in steeply dipping shear/hydrothermal breccia zones and as mantos. At El Toro, hydrothermal fluids appear to have risen along several E-W-trending brecciation zones tens of metres in width; gold values above 1 g/tonne exist over an area of at least 2.5 x 0.5 km and high-grade manto deposits extend outwards from the breccias for at least 300 m. Mineralisation at Igor is controlled by steeply dipping, mainly longitudinal faults and fractures that cut a SE-plunging anticline. Faults and fractures normal to an anticline host the narrow, polymetallic veins of the former Algamarca mine, which in their upper parts locally contain oxide ores grading over 1 oz/tonne Au. Porphyritic intrusive igneous rocks are found at or near virtually all the deposits and there appears to be a genetic relationship with magmatic activity. Principal exploration targets are large, relatively low-grade deposits suitable for cost-efficient bulk mining and heap leaching., The hydrothermal deposits are hosted by moderately to strongly folded Lower Cretaceous distal sandstones and are Middle to Late Miocene in age.

The contiguous deposits produced 84 000 t of fine copper in 2001, almost entirely from reserves of 331 000 000 t of supergene ore grading 0.52% Cu. The development of 464 000 000 t of largely hypogene material at 0.61% Cu is under consideration. Porphyry intrusion and hypogene mineralisation in the district occurred at around 62 Ma, marking local termination of magmatic activity. Subsequent supergene activity, controlled by local subplanar landforms and highly permeable breccia zones, generated profiles of varying thickness and complex age relationships from the late Eocene to the Pleistocene., The contiguous deposits produced 84 000 t of fine copper in 2001, almost entirely from reserves of 331 000 000 t of supergene ore grading 0.52% Cu.

Most problems at Santa Rosa, in Panama, have been due to the high clay content of the ore, low leaching rates requiring crushing to 80% passing 9.5 mm, and heavy rainfall. The crushing plant, designed for 7 500 t/d, has been modified to allow processing of higher tonnages even during the rainy season without excessive blinding or plug-ups; the record is 13 230 wet tonnes in 24 h. The adverse effects of high rainfall have been overcome through separate management of storm water, which now runs off a heap overliner into a lined ditch, and process solutions which are now conveyed to the ponds in pipes. This has allowed optimum chemical conditions to be maintained for the process solutions and storm water to be run off into the 415 000 m3 unlined excess solution reservoir, where it can be retained for make-up water during the dry season or discharged from the site when an excess accumulates., Most problems at Santa Rosa, in Panama, have been due to the high clay content of the ore, low leaching rates requiring crushing to 80% passing 9.5 mm, and heavy rainfall.

Contemporary mine modelling at Santa Rosa has integrated exploration, geology, mine engineering and mine development into a single package. Rock chip sampling adjacent to old mines and adits began in 1985 and geological interpretaion of drillhole and surface data has evolved as exploration continued. The current stratigraphic model has been revised several times to show the relationship between rock type, mineralisation and alteration. The deposit is localised on the southern flanks of a strato-volcano and is a typical epithermal gold deposit of probable late Tertiary age. Gold mineralisation is associated with conjugate NE-trending structures and N-S-trending extensional fractures. Mineralising fluids migrated through competent and impervious mafic agglomerates and lapilli tuffs along a narrow NE conduit zone, forming multi-stage, banded, sheeted N-S quarz veins, and permeated the more porous wall rocks of overlying tuffs and sediments. The mass of feldspar porphyry andesite above appears also to contain gold where hydrothermal flow has modified the rocks. Three minable pits have been delineated at Santa Rosa and Alto de la Mina and the most recent estimate of proven and probable reserves, completed in mid-1994, indicates 12 300 000 t ore averaging 1.486 g/t Au and minable at a stripping ratio of 3.15:1. Resource and reserve models were based on assay results, geology, mining and processing costs and used a three-dimensional block model with interpolation of grade values obtained by indicator kriging. Pit slopes of 50 degrees between haul roads or 42 degrees including haul roads are based on most-likely design slopes from geotechnical studies. Final pit designs are based on optimised pit designs., Contemporary mine modelling at Santa Rosa has integrated exploration, geology, mine engineering and mine development into a single package.

Santa Rosa is a mid-Tertiary, volcanic-hosted, gold-silver deposit, Current proven and probable reserves are 8 900 000 t grading 1.5 g/t gold, mineable by open pit and amenable to heap leaching. It is the product of hydrothermal mineralisation along an arcuate segment of a caldera collapse ring fault in a probable island arc maar volcanic setting. This segment was later broken by radial faults. Gold occurs principally as electrum, finely disseminated through intermediate tuffs and associated with pyrite. The nearby Alto de la Mina deposit displays stockwork silica-pyrite-gold in a tectonically and hydrothermally shattered andesite flow. Miocene epithermal mineralisation was accompanied by central silicification and pyritisation and more distal argillisation. An andesite flow cap rock at Santa Rosa played a pivotal role as an upward permeability barrier. Highest gold grades and most intense alteration occur closest to the ring faults and immediately beneath the andesite flow. Supergene alteration effects on the gold distribution are minimal., Santa Rosa is a mid-Tertiary, volcanic-hosted, gold-silver deposit, Current proven and probable reserves are 8 900 000 t grading 1.5 g/t gold, mineable by open pit and amenable to heap leaching.

The development of the Santa Rosa and Alto de la Mina gold deposits by a joint venture between two Canadian companies, Boliden Canada and Greenstone Resources, is described. Proven and probable reserves stand at 11 300 000 tonnes grading 2.1 g/t Au with a cutoff grade of 0.857 g/t. The Santa Rosa deposit is the larger of the two, carrying 8 900 000 t at 2.06 g/t Au. The Alto de la Mina holds the balance of 2 600 000 t at 2.2 g/t Au. Only a quarter of a mile will separate the two pits., The development of the Santa Rosa and Alto de la Mina gold deposits by a joint venture between two Canadian companies, Boliden Canada and Greenstone Resources, is described.

s, GNIS, Approximate geocoding, Charles Beebe Turrill was born on March 26, 1854, in Folsom, California, and died in San Francisco, on May 11, 1927. He practiced as an amateur photographer for twenty years before establishing the professional firm of Turrill & Miller Photographers circa 1900. The firm's studio would eventually be located in Turrill's home, at 57 Sanchez Street in San Francisco. Turrill was a man of many interests. In addition to his work as a commercial photographer, he was also an historian, collector, author and illustrator. In all of these pursuits, California was his greatest passion. Turrill's first (and only) book, California Notes, was published in 1876, when he was only seventeen. Later, his photographs were featured in several books on California history, such as Gold and Sunshine, Reminiscences of Early California (1922). Throughout his life, he authored numerous articles for The San Francisco Chronicle, The Monitor, and many other magazines and newspapers. Turrill was also an active member of over twenty local societies and associations, including the Society of Philatelic Americans, the Pacific Coast Numismatic Association, and The Society of California Pioneers. He held many important civic posts, such as California Commissioner at the New Orleans Exposition (1884-1886), Secretary of the California State Viticultural Commission (1889), and historian of Lincoln Grammar School in San Francisco. Next to his achievements as a photographer, Turrill was probably best known in his day as a collector. Over a lifetime, he amassed an enormous personal library consisting of thousands of books and ephemeral items, all relating to California history. The collection famously filled all three floors of 57 Sanchez Street. In an article published in The San Francisco Call and Post (September 17, 1921), Elford Eddy describes the experience of visiting Turrill: "Instead of walking into a photograph gallery, you find yourself in an old-fashioned San Francisco house, jammed, crammed, bulg, Title supplied by cataloger., good.
