Mining restarts

After much work and determination I have been able to restart operations in Liberia. With the cessation of Ebola, Liberia has returned to normal allowing the mining of our new concession.

REFURBISHING THE DREDGE:

 

The Dredge though originally designed for river dredging in the USA is being modified for use in the jungles of West Africa. Tiehnpo plans to modify the Dredge by building an all aluminum working platform, walk ways, outboard motor mounts, two 40hp outboard engines, GPS, depth finder, hot water heater for wet suits, on board spiral and Jig classifier, riffles, new suction hoses, two way communication, diving lights, and toilet.

 

The Dredge also requires that the engine and pump to be gone through and readied for the next 200 day mining season.
 
 
 
OPERATIONS:
 
Tiehnpo Resources plans to use the 10 inch Super dredge (the “Dredge”) as the sole dredging equipment for the Project. The dredge is simple, efficient, site specific and conservatively rated to handle 50 cubic meters of material per hour. It consists of a platform built on aluminum pontoons, a 167 hp diesel engine,  one (1) 3500 GPM Berkley water pump, and a 25ft long sluice box for recovery.  It employs only tried and proven technology, is constructed from industrial grade components, and is very reliable.  It is extremely easy to operate, is almost maintenance free, and will operate at depths of 30ft to 40ft with maximum suction where the highest gold values are recovered. 
 
 
 
CONCLUSION:
 
Tiehnpo Resources plans to ship the 10 inch Super dredge ( "Lucky Lady") to River Cess, Liberia for the 2013-14 Season. Work will continue 8 hours per day, six days per week (weather permitting).  A labor intensive operation is expected requiring divers to take 3hr shift rotations.  The production estimate allows for time lost during start up, shift change, and shut down each day, and for any scheduled and unscheduled maintenance.  With the Lucky Lady (Dredge) processing 400 cubic meters per day and assuming a conservative half gram of gold per cubic meter, anticipated daily production would average approximately 200 grams or (6.4 ounces Au).

Exploration








Exploration conducted on the Permit Area confirms the existence of substantial placer gold deposits in the riverbeds, river bottoms, and related flood plains of the Permit Area. 



The gold bearing gravel of Block 320-A is located within the riverbeds (alluvial deposits) and also extends well beyond the riverbeds (elluvial deposits) in distances from 100 meters to half kilometer, depending on the width of the valley. The upper one meter of overburden is usually depleted in value, due to downward migration of the dense gold particles through water saturated soil. The gold bearing, pay zone gravel in the river is deposited on decomposed quartz lying in a fairly even horizon two to three feet thick lying on bedrock or on a "false bottom" of hard blue clay.  More importantly, the gold is not attached to rocks or other minerals and thus requires no milling processes or chemicals to separate it from the surrounding gravel.



Tiehnpo Resources believes that the source of the gold found in the rivers of Block 320A are eroding from ore bodies located in the surrounding hills. Through yearly runoff, the soils are washed into the rivers where the lighter sediments wash downstream and the gold settles to the bottom.



Tiehnpo Resources has imported dredging equipment to conduct tests on the River. These tests confirm previous geological work done on the Permit Area and have yielded an average of 58 grams of gold per Dredge per day, with most recoveries ranging from 0.5 to 3.0 grams/Au per cubic meter. Historically in some locations up to 5 grams/per cubic meter (approx. 1/4 ounce gold per cubic yard) have been reported.  Geological reports estimate there are approximately 5,824,000 cubic meters of gold bearing material in the four (4) river systems. (copy of reports are available)


dredges on the river








Liberia is an equatorial nation on the West Coast of Africa where it receives 70% of its very high annual rainfall during a June through October rainy season. Liberia has hundreds of kilometers of rivers with conditions amendable to suction dredge mining.



Typical to most of the country, the gold found in Liberia originates from hydrothermal fluids rising along conjunctures of faults and shear zones producing areas rich in hydrothermal clays and iron oxides which provide the best environment for the development of coarse-grained crystalline gold. The laterite capping is of pre-fault occurrence, the events of natural erosion, folding, and fracturing has transported the capping laterite and quartz to form alluvium deposits along the base of the mountains. The quartz rock has survived the softer rock thus producing gravel bars composed of rounded and semi-rounded quartz aggregates. The gold, which is found along with the quartz, is subjected to transport by stress action and is re-deposited along the courses of the creeks and rivers.
