This work should be concluded early in the second quarter with a ground IP-Mag geophys- ics survey to follow covering the 60% of the mineralized trend not covered by the Mammoth survey. Centerra plans to perform additional diamond drilling in the second half of the year testing targets generated from the combination of their mapping and geophysics with historical results, and fol - lowing up on prior drilling. Pan American Silver Corp. [PAAS- TSX, NASDAQ] owns and operates six mines in Mexico, Peru, Argentina and Bolivia. The company's largest opera- tions, in terms of production, are the La Colorado and Dolores mines in Mexico. They were expected to produce between 7.4-7.7 million ounces and 4.5-4.9 mil- lion ounces of silver in 2018, respectively. Pan American recently agreed to acquire Tahoe Resources Inc. [THO-TSX, NYSE] in a US $1 billion transaction that will create the world's largest premier silver mining company. Riverside Resources Inc. [RRI-TSXV] is a well-funded prospect generator that has demonstrated consistent growth by assembling a portfolio of precious and base metal projects. The company recently said it is raising $2.3 million from a private place - ment financing to fund drilling at the Cecilia Project, which is located in Sonora state, about 40 km from the Mexico-US border. Over the past year, Riverside has con- ducted channel sampling of surface areas over the four main Cerro Magallanes target areas at the 100%-owned Cecilia Project. Riverside has said it wants to see drilling in the near future to test the targets that have been generated. The district-scale targets show strong gold values and good continuity, said Riverside President and CEO, Dr. John-Mark Staude. SilverCrest Metals Inc. [SIL-TSXV] recently announced an updated min- eral resource estimate for its Las Chispas property in Sonora. The company is now looking ahead to a further resource update and a preliminary economic assessment (PEA) due in the first quarter of 2019. In keeping with that plan, the company wants to continue exploration drilling with six to eight core drills running. The company said inferred mineral resources are estimated at 4.3 million tonnes, grad - ing 3.68 g/t gold and 347 g/t silver, or 623 g/t silver equivalent. The inferred resource estimate includes 511,800 ounces of gold and 48.3 million ounces of silver, or 86.7 million ounces of silver equivalent, using a 150 g/t silver equivalent cut-off grade and minimum true vein width of approxi - mately 1.5 metres. The Las Chispas property is located approximately 180 km northeast of Hermosillo. It consists of 28 concessions totalling 1,400 hectares. Between 1880 and 1930, several mines on the property are thought to have yielded approximately 100 million ounces of silver and 200,000 ounces of gold. Sierra Metals Inc.
