EL LIMON MINE<br />
• The existing mineral process at El Limon consists of two-stage<br />
crushing, milling, gravity separation, flotation, cyanidation, Merrill-<br />
Crowe precipitation <strong>and</strong> smelting. Amalgamation in small ball mills<br />
(cocos) has historically been performed as well. The final product<br />
sold by El Limon is gold/silver doré. Average monthly production<br />
during upgrade has been 250 ounces per month (10% of upgraded<br />
capacity).<br />
• A 2-stage crushing plant is operational on site. The crushing plant<br />
historically operated one shift per day at 10-12 tonnes per hour but<br />
has capacity of 20 tonnes per hour, providing sufficient crushed rock<br />
to feed the mill. The crushing plant consists of a jaw crusher, cone<br />
crusher, vibrating screen <strong>and</strong> associated belts <strong>and</strong> bins. A nominal<br />
3/4” product is supplied to the mill. This crushing plant will be<br />
renovated <strong>and</strong> upgraded to allow a smaller (-1/2”) nominal feed to<br />
the mill.<br />
• A $1.7 million upgrade is underway under the operational control of<br />
Para. The planned upgrades includes the installation of a second ball<br />
mill <strong>and</strong> other equipment required to increase mill throughput to 200<br />
tpd. The proposed mineral process has not changed. Amalgamation<br />
has been eliminated. Project completion is Q1 2016<br />
• Recent head grades <strong>from</strong> El Limon mine development workings have<br />
exceeded 100 gpt<br />
