Northern Empire Files Technical Report on Sterling Project-Nevada 709,000 oz Au at 2.23 g/t
VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 2, 2017) - Northern Empire Resources Corp. (TSX VENTURE:NM) (the "Company" or "Northern Empire") is pleased to announce filing of the NI 43-101 resource estimate report on the Sterling Property, located in Nye County, Nevada (the "Sterling Property") owned by Sterling Gold Mining Corporation ("SGMC"), a wholly owned subsidiary of Imperial Metals Corp. ("Imperial Metals"). The Company has previously announced entering into a letter of intent with SGMC to acquire the Sterling Project (for further details please refer to the Company's news releases dated February 15, 2017 and April 3, 2017).
The Sterling Property hosts four different gold deposits, three of which are Carlin-type deposits (Sterling, Daisy, SNA) while the fourth is defined as an epithermal gold deposit (Secret Pass).
Table 1 through Table 4 outline the in-place gold resource estimates for the Sterling Property. All resource estimates are derived from a 3D block model using ordinary kriging methods. For the Sterling Deposit, the resource estimate was separated into two categories, namely surface (pit constrained) resources and remaining non-pit constrained resources. All resources have an effective date of March 29, 2017, and all the resources are considered Inferred. The report was completed by Norwest Corporation.
Bolded text indicates the base case estimate.

These resources are based on drilling and assaying completed by Imperial Metals and other previous operators on the Property. Five separate open pits and two underground mines were operated on the Property, as recently as 2015.
Data used to calculate the resources was collected by the current owner and previous operators of the property. Assaying was done by both internal and external labs. Norwest has reviewed the data and found it to be of sufficient quality to apply an Inferred Resource classification.
About the Sterling Project
The Sterling Property is located approximately 100 miles NW of Las Vegas on the eastern flank of the Bare Mountains within the Walker Lane Trend. The Sterling Mine is accessed via highway I-95 and gravel roads.
The Sterling Mine has previously operated as both an open pit and underground operation. Production records show that from 1980 to 2000 mining on the Sterling orebodies produced 194,996 oz gold ("Au") at an average grade of 7.44 g/t Au. Recoveries have averaged 88% without milling.
The Bureau of Land Management has issued a Finding of No Significant Impact ("FONSI") and approved the next phase of mining at Sterling. This permit was issued on May 12, 2016 and has an indefinite term.
To achieve the FONSI, Imperial Metals created designs for the new pits and heap leach facilities that Northern Empire will be able to use going forward.
Imperial Metals ceased underground mining of a separate orebody in 2015. Processing facilities, mine offices and staff are on site and are currently being used to rinse heaps from prior operations.
About Northern Empire
On February 15, 2017, Northern Empire announced that it entered into a letter of intent with Sterling Gold Mining Corporation, a wholly owned subsidiary of Imperial Metals Corp. to acquire a 100% interest in the Sterling Property, located in Nye County, Nevada, and certain royalty rights for claims located in Nevada and California. The Sterling Project is a fully permitted gold project with exceptional exploration potential and represents a unique opportunity for Northern Empire to rapidly transition from a grass roots explorer to developer.
