Gold Sands - Noreste del Perú

Plan Minero

Constitution Mining proyecta desarrollar la producción de Gold Sands a 630.000 onzas de oro por año.

La operación minera está programada para comenzar en 2012 (año uno) con una draga de rueda de succión a escala de piloto, en tándem (conjuntamente) con una planta flotante de tamaño apropiado. La draga recogerá arena mojada y gravilla y la planta flotante procesará dicho material para remover y capturar el oro.

La tasa de producción esperada de la minería piloto es de 48.000 onzas anuales.

Ubicación y Acceso

Constitution Mining controla 461 kilómetros cuadrados (178 millas cuadradas) de las Gold Sands al noreste del Perú, donde el sistema del río Marañón abandona las montañas de los Andes y se vierte en territorio plano pre amazónico. La vegetación local incluye especies que caracterizan al bosque lluvioso tropical. Sin embargo, debido a su proximidad a los faldeos de los Andes, el área posee un microclima con estaciones secas y lluviosas no definidas. El promedio de agua caída es de 28 centímetros (11 pulgadas), cayendo la mayor parte por la tarde.

La empresa tiene posesiones territoriales en dos de los tres campos aluviales de Gold Sands. De ellos, el Campo Manseriche es, lejos, el más grande y el más importante. Está ubicado 470 kilómetros (292 millas) al oeste de la ciudad de Iquitos, ribereña del río Amazonas (población 400.000) y 240 kilómetros (149 millas) al norte de Tarapolo (población 108.000). A las dos ciudades puede llegarse por vuelos charter y ambas cuentan con vuelos comerciales diarios a Lima.

Aprovisionamiento y equipo pesado puede ser trasladado a Campo Manseriche en barcazas desde Iquitos y también desde Yurimaguas, a 455 kilómetros (283 millas), sobre el río Huallaga. Además, cargas pesadas pueden ser transportadas en camión desde Bagua, a 280 kilómetros (174 millas) de distancia, sobre un camino que depende del tiempo hasta la aldea de Saramiriza, donde la empresa se ha estableciendo su base logística y de administración. Saramiriza está cercano al centro de Campo Manseriche.

Historia del Distrito Gold Sands

El río Marañón, que por millones de años ha estado vertiendo arena, gravilla y oro a la propiedad controlada por Constitution Mining, es, de acuerdo a la leyenda, la fuente del oro pagado al conquistador Pizarro por el rescate de Atahualpa, el último emperador de los Incas. En pequeña escala, generalmente primitiva, la minería en Gold Sands ha continuado desde aquella transacción. En la era moderna, los esfuerzos de exploración y desarrollo incluyen: 

Decenio de 1940. Una empresa alemana operó una línea de dragado de 10 metros cúbicos, 10 kilómetros (6 millas) río abajo desde Saramiriza (que ahora es el sitio seleccionado como base logística y administrativa por Constitution Mining). Su partida fue debida a la II Guerra Mundial. 

1979 a 1980. La compañía Panasa (una empresa local peruana), recuperó oro procedente de la isla El Banco, 14 kilómetros (8.7 millas) al noroeste de Saramiriza. Se usó equipo pesado de movimiento de tierra con resultados positivos, pero era vulnerable a las altas mareas que afectan al área de Saramariza.

1983. Un grupo de emprendedores canadienses operaron una pequeña draga de succión, 15 kilómetros (9.3 millas) al sur de Saramariza. Ellos abandonaron el proyecto bajo presiones legales y técnicas causadas por su proximidad a un oleoducto.

1989. Mutiferros SA, una empresa brasileña, introdujo cuatro dragas de succión a Gold Sands, pero su diseño eventualmente demostró ser poco apropiado para el depósito.

1991. Los geólogos Montoya y Medina de Centromin Perú S.A. realizaron un muestreo a gran de la grava aluvial que cubre alrededor de 80 kilómetros a lo largo del Río Marañón. El grado medio de las 26 muestras de oro era de 253 mg/m3, alcanzando de 100 a 400 mg/m3, con los grados más altos existentes, a 40 kilómetros debajo del Cañon de Manseriche, en la mitad del río hacia abajo.

1990 a 1992. La Compañía Mónica de Iquitos perforó una concesión de 10 kilómetros cuadrados (6 millas) en Campo Manseriche, comprobando grados de 295 milígramos por metro cúbico a una profundidad de 32 metros (105 pies). No lograron financiar mayores desarrollos y abandonaron su concesión, la cual fue tomada en 1995 por Lomas del Marañón SA. 

1994. Matsag Minerals, empresa controlada por Glencor de Suiza, adquirió concesiones cerca de Puerto Elisa, 12 kilómetros (7.2 millas) río abajo, desde Saramiriza, cubriendo un vasto meandro abandonado del río. Usaron como draga de canjilones en línea de 3 pies como herramienta para conseguir muestras masivas, pero no realizaron perforaciones. Sus concesiones fueron posteriormente adquiridas por Lomas del Marañón. 

1995 a 1997. Lomas del Marañón instaló un campamento y operó un lavadero de carbón con una excavadora flotante. Su sistema de sluices mal diseñado produjo baja recuperación.

1998. IHC Meerwede de Holanda realizó pruebas metalúrgicas preliminares y estudios de ingeniería.

1999 a 2000. Intereses brasileños privados, bajo la dirección técnica del ingeniero aluvial Peter Rich, demostró la viabilidad de recuperar oro de las arenas y gravillas en el área de Saramiriza, usando dragas e cangilones en línea y buscó sin éxito en Canadá un financiamiento del proyecto en tiempos de precios bajos del oro.

2006. El consultor James Prudden, de la Corporación Aurum, realizó el muestreo de reconocimiento de los depósitos de oro a lo largo del Río Marañón, cubriendo alrededor de 100 kilómetros río abajo del Cañon de Manseriche. Las veinticuatro muestras recolectadas hicieron un promedio de 169.2 mg/m3, con las muestras obtenidas en los 45 kilómetros más abajo hacen un promedio de 268.9 mg/m3. Prudden concluyó que "esta longitud de 100 kilómetros del río podría ser considerada un distrito de oro muy grande que requiere una evaluación sistemática".

2007 a 2008. Temasek Investments Inc., siguiendo las anteriores recomendaciones de Peter Rich, consolidó el área del proyecto, demarcando y registrando terrenos adicionales en Campo Manseriche y en otros dos campos cercanos. 

2008. Constitution Mining adquirió opciones en concesiones en Manseriche y campos cercanos, ganando de esta manera control del 60% de todas las concesiones en el área y transformándose en el mayor operador en Campo Manseriche.

 

Small-scale, low-tech mining of the Gold Sands predates the arrival of the Spanish in Peru and continues to this day.

Geología y Mineralización

Perú produce anualmente 5.6 millones de onzas de oro y casi la mitad viene de la mina Yanacocha de Newmont.

En otros sitios, la producción aluvial ha ido creciendo, de 200.000 onzas en 1991, a una tasa actual de 500.000 onzas por año. La mayor parte de ellas vienen de los cuatro mayores campos aluviales de Perú – Iquitos, Ucayali, Madre de Dios y Marañón-Santiago, donde se encuentran los intereses de Constitution Mining.

Depósitos de oro aluvial a gran escala tienden a formarse donde montañas forman pliegues colindantes con planicies. Un depósito de oro puede acumularse en las planicies si (1) el oro se encuentra en las montañas contiguas y (2) un enérgico sistema fluvial corre a través de las montañas acarreando arenas y gravilla portadoras de oro. Cuando el sistema fluvial llega a la planicie, la velocidad del agua cae, y la arena, gravilla y oro se establecen. (Ver Preguntas Frecuentes 2)

En el caso del Campo Manseriche, los ríos Marañón y Santiago surgen de elevaciones máximas de 2.900 metros (9.500 pies) y 3.500 metros (11.483 pies), respectivamente. En su transcurso de 900 kilómetros (560 millas) a través de los Andes, ellos son alimentados por la cuenca de drenaje Marañón-Santiago, que alberga algunos de los depósitos de oro más grandes del mundo y operaciones mineras de oro (incluyendo Yanacocha, Cerro Corona y Fruta del Norte). Cerca de la base de los Andes, a una elevación de sólo 170 metros (557 pies), los ríos convergen en el Pongo de Manseriche. Entonces ellos desembocan en una llanura ancha y depositan su carga sedimentaria.

Modelo Geológico

El modelo geológico para la cuenca del Marañón consiste en un sistema aluvial entrelazado que ocupa el eje de una sumersión de la orilla, este sinclinal crea la cuenca, la que es más favorable por su estructura para la reelaboración sedmiento. Este complejo del río masivo ha emigrado hacia el norte a través del tiempo geológico, creando numerosos sistemas de abandonados meandros que a través de la corriente capturan enormes volúmenes de sedimentos refundidos que contienen oro. La morfología predominante del oro permite que este emigre más distante en este ambiente fluvial que en los sistemas aluviales clásicos. Por consiguiente, el oro puede ser encontrado en los sedimentos de Rio Marañón a más de 130 kilómetros debajo del Cañon de Manseriche, explicando así la distribución extendida del metal en todas partes de la cuenca donde están localizadas las propiedades de Constitution Mining.

A White Paper on the Gold Sands of Peru

 

 

In this White Paper we shall examine the Gold Sands of Peru located in and around the

Maranon‐Santiago District in Northeastern Peru. The Gold Sands of Peru constitute what is

called a gold sands deposit ‐ precious metals deposited in a trap site.

One could make a parallel between these gold sands and the oil or tar sands found in Canada

and Venezuela. As with the valuable oil trapped inside of so‐called oil sands, the Gold

Sands of Peru have not been economically efficient to mine in the past. But just as with the

oil sands of Canada, technology is now available that enables the mining of such sands.

Consider that with the application of recently developed technology, Canada’s oil sands

now provide up to 44% of all Canadian oil production, the power of a new mining technology

becomes both obvious and promising.

 

Given an appropriate technological method of extraction, precious‐metal alluvial deposits

are perhaps the most satisfactory type of mineral deposit to explore for. That is because the

gold or silver is usually minable at a low cost and within an efficient time frame. Gold

sands style deposits of gold or silver also usually hold the most promise because they have

been formed by fast‐running streams which can serve as a most efficient conduit for concentrating

precious metals.

 

It is from such alluvial concentrations of gold and silver that most metals have been prospected,

identified and mined. Such gold sands deposits are often referred to as “large scale”

–as opposed to “regional scale” or “small scale” –processes that are geologically different

in their formation and presentation.

According to Dr. Fuchter (Willem Anton), “In [such] areas, exploration is guided by morphology

and sedimentology of alluvial fans. Experimental studies show that when trenches

form the fan‐head of alluvial fans, deposits of heavy minerals that form there are reworked

and frequently re‐deposited in the more distal regions of the fan… Concentrations of heavy

 

 

 

minerals in the proximal channels and distally located facies is confirmed by models of the

Witwatersrand placers.”

 

This kind of concentration within the alluvial flood plain offers the prospect of an enormous

amount of gold, given modern dredging techniques that have opened up new mining

horizons. Again, from Dr. Fuchter:

Gold sands are associated with sub‐mature to mature landscapes. They are

found in the drainage basin, as gulch and creek placers; in the channel system, as

alluvial fan or plain deposits. … Gold sands minerals are generally coarser

grained in the upper reaches of a placer gulch, creek, stream or river, and finer

grained in the lower reaches of placer rivers and alluvial fans. Richer and

coarser nuggets are commonly deposited with coarser sediment (gravel) and

the finer gold particles with sandy fractions. The gold in gold sands deposits

generally increases in fineness with increasing distance from the source.

 

Gold in sedimentary basins is typically much easier to mine than that which is hosted in

hard‐rock environments from which the gold originated. The gold, usually in the form of

flakes, blebs and nuggets, tends to settle in the loose gravels in such a way as to leave the

smaller sized gold particles nearer to surface. Over millions of years, the transportation and

depositing process can yield huge areas of mineralization. The key ingredient to discovering

these large regions of gold sands is that there must exist significant upland terrain that

hosts the origin of the gold. The Gold Sands district of Northern Peru is indeed such a location.

That Peru should offer additional gold mining promise should come as no surprise. Peru is

actually the world's fifth largest gold producer and an ancient producer of gold as well. Civilizations

starting well before the Incas produced gold and then molded it into various decorative

and sacred shapes, including statuettes, masks and funeral figures. The Peruvians

cultural affinity for producing and shaping precious metals, especially gold, is present today

throughout the culture. Small‐scale mining takes place throughout the country and employs

hundreds of thousands of individuals.

 

It is the Inca, of course who have left the most indelible mark. They called gold the “sweat

of the sun” and used forging techniques developed by the Chimu Empire of northern Peru

some 400 years before the arrival of the Spanish Conquistadors. Interestingly, while gold

was an integral part of the Inca society, it was not mined but taken from rivers over the centuries

in the form of flakes and nuggets. This sort of collecting yielded extraordinary riches.

When the Spanish conquered Peru, they are said to have taken 11 tons of gold and 22 tons

of silver back with them, melted down from Incan statuary into ingots.

 

Geology of the Gold Sands

 

The Peruvian ancients extracted gold from rivers and alluvial plains, such as the gold sands.

Today, as already mentioned, one of the most promising ways of finding gold in Peru is via

alluvial gold fields. Four major alluvial gold fields are located in Peru. They are the

Maranon‐Santiago, the Iquitos, the Ucayali, and the Madre de Dios‐Pando.

The Maranon‐Santiago –the gold sands of Northeastern Peru ‐ drainage basin is named after

the two rivers that drain into the region, which covers an area of some 120,000 square

kilometers. The age of most of the gold mineralization in the highlands of the Maranon‐

Santiago river system is tertiary, and specifically Miocene. However, Eocene‐aged tectonism

resulted in the formation of the eastern foothills of the Andes which effectively formed a

barrier directing all erosion from the hinterland towards a basin on the western side of the

Manseriche Gorge.

 

For millions of years the two major rivers systems of the Maranon and the Santiago have

been flowing through the gold‐rich Andean mountains of Peru and Ecuador on their way

down to the Manseriche gorge in Northeastern Peru. Here, the river waters deposit loose

gravel and sand. The metals that are eroded from the primary deposits in this drainage basin

have only one exit point, and that is through the gorge.

 

It is the sequence of constant erosion, glacio‐fluvial concentration, fluvial transport, collection

in an intermediate (or series of intermediate) basin(s), and final alluvial concentration

in the Rio Maranon flood plain, that provides the mixing and concentration which accounts

for the regular gold values in the sands and gravels as indicated by all the work carried out

to date.

 

The most notable operation was that of a private Peruvian company, Cia Monica de Iquitos,

which completed some 500 drill holes and established a resource. This work was verified

and confirmed by a Russian government consulting company, Sojuzkarta, which twinned

some holes and took bulk samples by backhoe. Their drill results as well as those from the

collection of bulk samples were used to estimate a grade of some 300mg/m3 based on a

fineness of 850 for correction to pure gold.

 

The study also indicated that grades tended to increase with depth, and that much of the

gold tends to be considerably fine in size, indicating the possibility of increased recovery

(and therefore grade) with appropriate recovery techniques (jigs and bowl concentrators).

In general, the geological resource potential can be expected to be considerable and more

than sufficient to sustain a fleet of high capacity dredges working over a long timeframe

.

The Gold Sands district indicates the potential for as much as 150 million of ounces of mineable

gold. Such gold deposits, it is estimated, can be mined profitably at prices as low as

US$150/ounce. Since gold has been no lower than US$250 an ounce for the last 35 or so

years, and as of this writing trades in a range between US$600 and US$1,000, it is likely that

the US$150 figure – on the low end – will not be seen again under almost any economic

scenario (certainly not for the foreseeable future).

 

The 150 million ounce figure compares favorably to some of the largest gold mining operations

and deposits in the world operating in the area of Peru and environs.

 

 

Three of the better‐known regional feeder deposits are…

Newmont Mining’s 37 million‐ounce Yanacocha gold mine which produces

approximately 3 million ounces per year

Goldfields Cerro Corona mine which currently produces some 350,000 ounces

per year but which is, reportedly, ramping up to produce over one million

ounces per year, and

Kinross Gold’s recently acquired Aurelian deposit which contains roughly 14

million ounces of gold.



Gold Sands Like Tar Sands

 

We have already alluded, above, to the Northern Canadian tar sands. The opportunities may

be considered similar for the Peruvian Gold Sands. The primary difference between gold

sands and tar sands is that the oil in the tar sands is expensive to extract and very dependent

of the price of oil and natural gas. In fact, approximately 2/3rds of all gold ever mined

has come from gold‐sands‐style deposits.

 

How do tar or oil sands compare with Peru’s gold sands? Tar sands are actually bituminous

sands –also known as oil sands. They are a mixture of sand, clay, water and a dense petroleum

called bitumen. While these sands have been identified in quantity in Canada and

Venezuela, they have not been mineable until recently. Today, there is technology that can

separate the bitumen at an efficient cost.

 

As a result of the application of new mining technology, oil extraction in Canada’s oil sands

has been growing. In fact, 44% of Canadian oil production in 2007 was from oil sands. Almost

unnoticed, as a result of successful oil sands production, Canada has forged ahead of

all other countries in providing oil products to the United States.

Because of recent success in extracting large quantities of oil from oil sands, such sands are

now considered part of the world’s oil reserves. Up to two‐thirds of the world's total petroleum

resource is now considered to reside within oil sands. About 1.7 trillion barrels are

placed in the Canadian Athabasca Oil Sands along with over 200 billion barrels in the Venezuelan

Orinoco oil sands. In total, estimates of oil sand reserves just in Canada and Venezuela

are said to be somewhere around 3.6 trillion barrels compared to 1.75 trillion barrels.

 

Gold Sands, Too

 

Just as oil sands have yielded their riches to advancing technology, so gold sands are starting

to yield theirs – and in an environmentally friendly way as well. Recent advances in

dredging, pumping, and processing technology allows for the recovery of gold from unconsolidated

gravels without the use of dangerous chemicals such as cyanide and mercury, and

represent a paradigm shift which may change the way the gold mining industry operates in

the future.

 

Meanwhile, new 'Dutch‐based' dredging and alluvial processing technologies allow for the

efficient and clean exploitation of low‐grade mineralized gravels. The producer of the new

alluvial mining technology is giant IHC Merwede, a world market leader in the construction

of sophisticated and specialized dredgers. With in‐house expertise of ore‐body characteristics

and process plant interfaces, IHC Mining designs and manufactures tailor‐made stationary

dredging equipment such as cutter suction, bucket wheel, bucket ladder and grab

dredgers, as well as (onboard) screening and gravity separation systems (Jigs).

 

The positive environmental factors associated with Gold‐Sands style dredge mining make it

far superior to the last great technological shift in the mining business ‐ heap leach technology.

With heap leach, the mined ore is “crushed into small chunks and heaped on an impermeable

plastic and/or clay lined leach pad where it can be irrigated with a leach solution

of diluted cyanide to dissolve the valuable metals. The cyanide is difficult to get rid of

and often ends up in the environment.” (Wikipedia)

 

New, modern dredging techniques have the potential to deliver large tonnage, low‐grade

deposits in great quantity. In general, the geological resource potential can be expected to

be considerable and more than sufficient to sustain a fleet of high capacity dredges working

over a long timeframe. Moreover, dredging projects can be rapidly developed and have

short lead times.

“The low capital investment together with lower grades necessary to form workable deposits

make gold sands an attractive deposit type to look for. Mining and recovery is comp

aratively simple, fast, and inexpensive. Gold Sands deposits are more attractive to the

small‐scale operator and junior mining company.” (Dr. Fuchter)

The Gold Sands of Peru provide a mining exploration company the advantages of highly

promising mineralization along with low extraction costs within an environmentally

friendly technological framework. For innovative and aggressive mining firms, Peru’s Gold

Sands may indeed offer a “plateau of promise.”
