OGI OrganiGram Holdings Inc

Organigram Holdings Inc. (TSX VENTURE:OGI) (OTCQB:OGRMF) (the “Company” or “Organigram”), a leading licensed producer of medical marijuana based in Moncton, New Brunswick, is pleased to announce that  it has initiated the process for re-certification as an organic producer of cannabis in Canada with ECOCERT Canada.

Organigram is currently undergoing a significant expansion of its facility to meet the growing needs of our business. In order to meet the anticipated demand for both mineral and organic production, the company has reconfigured their existing cultivation space and are in the process of building new areas devoted only to organic production.

As part of the process, Organigram submitted a comprehensive action plan to ECOCERT Canada, part of the Ecocert group, one of the largest organic certification organizations in the world, outlining the company’s approach to the growing and segregation of both product lines. The plan is designed to ensure the integrity of organic products within their facility, and was approved by ECOCERT Canada in September 2017.

The re-certification process continues with a series of onsite inspections. These inspections will review the cultivation process starting from the transition to organic stock material through to harvest and packaging, and will evaluate the successful execution of Organigram’s action plan.  These inspections will confirm the company’s compliance with the organic standards: CAN/CSGB 32.310(2015)- General Principles and Management Standards and the CAN/CSGB 32.311(2015)- Permitted Substances Lists.

The company will work diligently to complete the re-certification process before July 2018.
