I.                General Introduction

Junefield Mineral Resources Holdings Limited was founded in 2008, after four years of development in Peru and Ecuador, we have grown into a integrated organization that leads with Geological Exploration Institute. We built a platform includes mine prospecting, exploration, mine development, operating and production. The Geological Exploration Institute consists exploration department, geophysical department, project department, general information department, manufacturing, test and analysis center. The exploration department has three subdivisions: Copper exploration team, iron ore exploration team, gold and polymetallic exploration team, coal geological exploration team.
At present, our company owns more than 930 concessions in Peru, total area reaches 7600 square kilometers. Some of the concessions have huge potential, located at the west Cordillera coastal region and Cusco District, Apurímac District, Puno District in Andes. We also have some project sites that are based in Putan de Pondo District of Yarabamba Province, Ilo District and Puno District of Moquegua Province. We are also going to build a regional coal base in Santo District of Ancash Province.
In addition, our company possess two gold mine in Ecuador, Florida gold mine and Muluncay gold mine. We also have the intention to acquire the Rio Blanco gold mine recently.

II.                Project Overview
     1.       Iron Mine Project
Our company owns a number of iron mine concessions that covers 5000 square kilometers area, the exploration is in progress and has some positive results so far. There are three projects that have reached the exploration and development stages:
·Mariela Project
·Ferro Sur Project
·Morritos Project
     (1) Mariela Iron Mine Project
Mariela Iron Mine Project is located in the Southern part of Peru, Arequipa District. It is 78km from the district capital, Arequipa City, and 20km from the coast line.
Mariela Project was acquired by Junefield Mineral Resources Holdings Limited through options method in early 2012, in the meanwhile, Junefield Group has become its Australia head company’s largest shareholder.

The industrial index for the resources marginal grade is initially set up at 20%TFe, and the average grade is approximately 40%TFe.
Since the number of drilling holes is limited, and there’s no control over the length and the depth of the mine, it is believed that the quantity of mineral resources will increase in the future.
(1) Ferro Sur Iron Mine Project
     Ferro Sur Iron Mine is located in Puno Province, Acora District of Peru.

     Metallurgical experiments
     The results from Don Javier porphyry copper mine project metallurgical experiments:
   ·Undressed ore has Cu 0.53%, Mo 0.045%, Sulfer 3.93%, Ag 6.94%, and small proportion of other elements;
   ·The sulphide has Cu distribution 87.69%, Mo distribution of 97.78%;
   ·The norms for Cu Mo preferential floatation experiments are: copper concentrate grade 24.24%, in which molybdenum grade 2.77%, silver grad 104g/t, copper recovery rate of 64.04%, molybdenum recovery rate of 80.51%, and silver recovery rate of 20.59%.


     Ore dressing process
   ·Ore dressing process: semi-autogenous griding + ball-milling + floatation.
   ·Product: main product includes copper concentrates; byproduct includes molybdenum, silver and gold.
   ·Copper recovery rate: 87.5%
     The project has completed the deposit exploitation economic research.

     Resource assessment
   ·Dr. William X. Chávez is a well know porphyry copper mine expert, after his visit on site in 2012, he pointed out that Don Javier is a well-developed Cu-Mo porphyry system, and the potential copper metal resource quantity for this project is more than 5 million tons.
   ·In this project overview, the resource quantity has only been calculated up to hole No.67, the construction work has reached to hole No.83 so far. The onsite engineers is very optimistic regarding the grade, after the laboratory test is completed, there will be an increase in the resource quantity estimate, especially there has shown good mineralization and industrial ore body in the two drilling holes of the No.3 mine belt.
   ·As more exploration works are carried out, the prospects for the project resource quantity is positive, and may become a large porphyry copper mine in Peru’s porphyry copper mine belt.
