Dynacor Gold Mines is pleased to announce that it has acquired an additional 1 550 ha of mining claims which are adjacent to the northern part of its Tumipampa property. These strategic acquisitions were made to ensure that the company controls the north-west and western lateral extensions of the mineralized skarn horizon associated with the Ferrobamba formation. The latter is well known for its gold (Au), silver (Ag), copper (Cu), molybdenum (Mo) et bismuth (Bi) mineralization. The total surface area of the Tumipampa property is now 4,200 ha, an increase of 58.5%, and entirely encompasses the polymetallic skarn structure that Dynacor is actively exploring.
The new claims were acquired in two steps. Firstly, 250 ha were obtained by registering these claims with the Ministry of Mines since they had been abandoned by their previous owners. A further 1,300 ha was purchased from a Peruvian company in exchange for a cash down payment and normal contractual terms relating to future exploration and the repurchasing of net smelter royalty (nsr) rights.
The Tumipampa project is located 500 km from the city of Lima, in the Circa district, Province of Abancay, Department of Apurimac. Dynacor Gold now owns a total of 4,200 hectares which are adjacent to concessions being explored by international mining companies such as: Bear Creek and Southern Peru. The northern part of the Tumipampa property is underlain by the limestone-bearing Ferrobamba formation which hosts the "Tintaya" deposit, a Cu-Au skarn deposit. Tintaya is a world class skarn deposit with more than 139 million tonnes of 1.23% Cu and 0.23 g/t Au. Tintaya is located approximately 197 km to the north-east of the Tumipampa property. Furthermore, as shown on the map below Tumipampa is located close to a series of recently discovered mineralized deposits such as Los Chancas (200 million tonnes of 1% Cu) (Southern Peru), Las Bambas (860 million tonnes of 0.93% Cu and 0.11 g/t Au and 0,02% Mo) (Xstrata) and Constancia (277 million tonnes of 0.05 g/t Au and 0.46% Cu) (Norsemont). All of these world class deposits are part of a Cu-Au porphry-skarn belt that is associated with the Andahuaylas-Yauri intrusive that is 300 km long and 150 km wide.
Two channel sampling campaigns were carried out on the Tumipampa property from July 2009 to January 2010. 613 channel samples (0.5 to 1.5 meters long) were collected and Dynacor also undertook a detailed mapping and surface sampling study in the claims that were recently acquired in the northern part of the property. The mineralized skarn structure is formed by metamorphic processes within the contact zone between the Ferrobamba limestones and the batholitic
Andahuaylas-Yauri intrusive body. On the Tumipampa property, the skarn structure is located in the north-north-west sector and follows a west-north-west and east-south-east axis. The skarn is ca. 4.0 km long and 1.5 km wide.
The 613 channel samples were collected from Zones 1-4 (see map below) and 330 samples (53%) had anomal gold (Au) grades ((greater than)0.01 g/t), 198 samples (32%) had anomal copper (Cu) grades ((greater than)0.01 %), and 44 samples had anomal molybdenum (Mo) grades ((greater than)0.0033%). Finally, it is important to underline that 144 samples (23.49%) had very significant gold or copper grades or both.
The percentage of significant results by zone is given below:
– Zone 1 : 9 samples (6.25%)
– Zone 2 : 58 samples (40.28%)
– Zone 3 : 35 samples (24.31%)
– Zone 4 : 42 samples (29.17%)
and the data for the 4 zones are given in the tables below.
