Osprey Acquires Option for Past-Producing Caribou Gold Mine in Nova Scotia

Vancouver, British Columbia--(Newsfile Corp. - September 7, 2017) - Osprey Gold Development Ltd. (TSXV: OS) (the "Company" or "Osprey") is pleased to announce it has entered into a definitive agreement (the "Option Agreement") pursuant to which it has acquired (the "Acquisition") an option (the "Option") to acquire the Caribou Gold Property ("Caribou Property") from John Logan Enterprises Ltd. ("Logan"). Pursuant to the terms of the Option Agreement, Osprey may acquire a 100% interest (subject to certain royalties) in 16 contiguous mining claims (256 hectares) hosting the past-producing Caribou Property located 80 km northeast of Halifax, Nova Scotia (see accompanying map for specific property location and details).

Company President Cooper Quinn said, "Having completed our legal and technical due diligence on the Caribou Project, we're very excited to add it to Osprey's portfolio. It fits well within our portfolio of historic high-grade producers in the Meguma terrane, and we believe Caribou has the potential to hold a sizable gold resource. We're looking forward to getting work started on the property, to begin generating targets in the high grade gold quartz stockwork zones, as well as to test to potential within the overlying argilites. Strategically, the project is in an excellent location, being on the road system, and only 13 kilometres from Atlantic Gold's Moose River Consolidated mineral processing facility."

About the Caribou Property

• Strategically located, 8 kilometres north of Atlantic Gold's Touquoy Mine and Moose River Consolidated mill site and completely surrounded by Atlantic Gold claimholdings (see Figure 1 below);
• Historic drill results in stockwork zones include 11.2 metres grading 10.86 grams per tonne ("g/t") gold in Hole CM-98-01 and 9.8 metres grading 12.2 g/t gold in Hole SB-88-11 [NTD: Source];
• Project area includes broad areas of Halifax Group argillites, a favored host rock for disseminated gold and whichat the Caribou Project are largely unexplored;
• Reported past production of over 100,000 gold ounces between 1869 and 1955, as reported in a historical technical report titled "NI 43-1 01 Technical Report For the Caribou Gold Property Upper Musquodoboit, Halifax County, Nova Scotia", prepared for Scorpio Gold Corporation by Guy Mac Gillivray, P.Geo. of W.G. Shaw and Associates Limited in a report dated October 8, 2008 (the "Historical Report");
• An inferred historic resource of 94,763 ounces of gold in 350,305 tonnes grading 8.81 g/t gold, uncut as set forth in the Historic Report (the "Historic Estimate"); and
• Using a grade cap for gold of 47.0 g/t (to compensate for nugget effect) the Historical Estimate for the Caribou Gold Property is 350,305 tonnes grading 5.83 g/t gold, or 67,425 ounces of gold;

The reader is cautioned that a qualified person has not done sufficient work to classify this Historical Estimate as current mineral resources and Osprey is not treating this Historical Estimate as a current mineral resource. While this Historical Estimate was prepared using the categories set out in Sections 1.2 and 1.3of National Instrument 43-101 as defined in the "Canadian Institute of Mining, Metallurgy and Petroleum Standards on Mineral Resources and Mineral Reserves Definition Guidelines" in effect at the time, there is no guarantee that it would be consistent with current standards and it should not be regarded as consistent with current standards. The Historical Estimate is relevant to obtain a reference to mineral potential present on the property. The Company has not undertaken any verification of the historical data upon which the historical estimates are based on.

The Historical Report discloses that underground production from the Caribou district was first recorded in 1869. Since then approximately 108,250 ounces of historical gold production has been documented from the property in various production records and reports. Mining and milling records indicate an average mined grade of approximately 13 g/t, with local areas of 68 g/t. The Historic Estimate includes distinctive zones of gold in stockwork veining hosted by shears within the anticline.These contain broader zones of high grade gold than normally seen in the camp.

Lode gold mineralization is interpreted to be controlled by a north-northwest striking low angle axial structure that cuts the 35 km-long Caribou-Cochrane Hill Anticline.

Osprey intends to plan exploration programs to test the argillites, extend known high-grade veins, and expand and test for new zones of stockwork veining.
