A battered silver miner produced some good news Thursday, while a popular healthcare play was under the weather. Here’s some small stocks making big moves on Thursday, March 31, 2016 (as of 11:15 am EST):

Americas Silver Corporation (TSX: USA) (USAPF) shares surged 32% to $0.245 on Thursday after the silver miner announced that consolidated silver production for 2016 is expected to be between 2.5 – 3.0 million silver ounces and 5.0 – 5.6 million silver equivalent ounces, while silver cash costs are projected to fall about 25% to between $9.00 – $10.00 per ounce with all-in sustaining costs projected to decline approximately 30%.

As well, shares of Dynasty Metals & Mining Inc. (TSX: DMM) (DMMIF) plunged 45% to $0.17 as the resource explorer/developer said that towards the end of the fourth quarter of 2015 and into the first quarter of 2016 to date, both tonnage and grade at its Zaruma Gold Project in Ecuador dropped significantly due to several factors including, amongst other things, a reduced number of trained miners available to work at the Zaruma mine.

GeneNews Limited (TSX: GEN)(GNWSF), meanwhile, reported that it has entered into a collaboration agreement with JTS Health Partners. The national healthcare management consulting and professional services firm will accelerate adoption of GeneNews’ menu of proprietary cancer tests, including its lead ColonSentry blood-test for assessing an individual’s current risk for colorectal cancer. GeneNews stock moved up 17% to $0.135 following the announcement.

In addition, shares of Patient Home Monitoring (TSXV: PHM)(PHMZF) slid 23% to $0.28 as the healthcare service company said due to continuing Medicare reimbursement reductions and market dynamics impacting all providers in the industry, the business experienced a decline in revenues. It added that a business acquired in September 2013, Logimedix, is no longer good fit.

Finally, Callidus Capital Corporation (TSX: CBL)(CCAOF) shares jumped 28% to $13.34 after the alternative lender announced that its fiscal 2015 revenue increase 73%, while its net income rose 48% from 2014.
