Top 5 Gainers on the TSXV Last Week

Last week saw a number of junior resource companies on the Toronto Venture Stock Exchange gain in share prices. Below are the five with the greatest increases.
Excelsior Mining (TSXV:MIN)
Excelsior Mining gained 358.33 percent last week. This remarkable increase came in the wake of an announcement by the company of the results of a prefeasibility study on its North Star deposit at the Gunnison Copper project in southern Arizona. The study showed figures as high as $1.24 billion for the net value of the deposit before tax. The NI 43-101 compliant study was completed by M3 Engineering and Technology Corp of Arizona, and showed an after-tax value of the deposit of $825.83 million, using a copper price of $2.75 per pound. This is a fairly conservative estimate – copper prices have hovered near $3 a pound in recent trading on the Comex in New York.
Samco Gold (TSXV:SGA)
Samco Gold, an exploration company engaged in the acquisition and development of mineral properties, focuses largely on gold and silver. The company gained 88.89 percent last week. On Jan. 10, the company announced it had entered into a participation and option agreement with Ricardo Auriemma, the company’s director, under which it has the option to acquire the right to participate in benefits arising from an Argentinean court’s judgment relating to a breach of agreement between Auriemma and Northern Orion Resources Inc. Funds from this agreement will allow the company to undertake further development of its gold and silver projects in Argentina, which includes the EDM and Corina properties.
Commerce Resources (TSXV:CCE)
Commerce Resources focuses on exploration and development of tantalum and niobium resources, as well as other rare earth elements. It gained 70.83 percent last week. On Jan. 10, the company announced its report from the 2013 drill program at its Ashram Rare Earth Deposit in Northern Quebec. The report confirmed additional and unexpected mineralization at the site. It also found mineralized material at the surface of the project, and encountered high-grade zones throughout. There is now an additional 60 or more miles of mineralization at the project than was previously known.
Regulus Resources (TSXV:REG)
Regulus Resources, a Canada-based mineral exploration company, gained 57.89 percent last week. The company holds a 50 percent interest in the Rio Grande copper-gold project in Argentina under a joint venture agreement with Pachamama Resources Ltd. Regulus is the project’s operator. The Rio Grande project is located in the province of Salta in the Puna of northwest Argentina, an area friendly to mining activity. Regulus also has other projects in Argentina, including the El Camino property, an iron-oxide-copper-gold prospect in the same province as Rio Grande. Its other Argentinian projects include La Frontera, Aguas Calientes and Catua. It has one prospect in British Columbia, the Fireweed deposit, which is a polymetallic deposit of sulphide type mineralization.
Calibre Mining (TSXV:CXB)
Calibre Mining gained 50 percent last week. Calibre is an exploration-stage company focused on both precious and base metal assets as well as mineral properties. It operates primarily in northeast Nicaragua’s mining triangle, known as the Borosi Concessions. This area has gold, silver and copper mineralization. The company owns the Primavera Gold-Copper Discovery, the Riscos de Oro Project, the Rosita D Concession and Inferred Resource.
