RISE PROVIDES HISTORIC METALLURGICAL DATA FOR I-M MINE


·

Recoveries derived from 2,011,000 tons of mill feed from 1936-1941.

·

Overall gold recovery of 96.3% reported at I-M Mine during period.

·

67.5% gold recovery by gravity methods.

·

27.6% gold recovery by flotation.


April 5, 2017 – Vancouver, British Columbia – Rise Gold Corp. (CSE: UPP, OTC: RYES) (“Rise” or the “Company”) announces the results from its study of metallurgical recoveries from the past producing Idaho-Maryland Gold Mine (the “I-M Mine”).   


The Company estimates the I-M Mine has produced 2,414,000 oz of gold at an estimated average mill head grade of 0.50 oz/ton (17.1gpt).  Our previous news release dated April 4th, 2017 provides the details of past production at the I-M Mine.


The Company has been compiling and processing the extensive collection of historical data from the I-M Mine since the completion of the acquisition announced on January 25th 2017.  The Company has completed a study of the reported metallurgical gold recovery during a period of continuous production from 1936-1941.


The Company possesses the original records of the detailed monthly reports for the mineral processing at the I-M Mine from the period of 1936-1941. The Company believes it possesses the complete records of the mine during this period. The I-M Mine’s historical financial statements, which recorded the results from bullion sales, appear to reconcile with the historical production and the reported metallurgical recovery rates included in the historical data that the Company has reviewed.


Total gold recovery from the processing of 2,011,000 tons of mineralized material from 1936-1941 is estimated at 96.3%, of which 67.5% is estimated to have been recovered by gravity methods.


Process Plant


In the period from 1936-1941, the I-M Mine was in full production and processed through two identical process plants located at the two mining operations within the I-M Mine Property, the Brunswick Mine and the Idaho Mine.


The Idaho mineralization had higher gravity gold recovery of 76% versus Brunswick at 64%.  The average flotation concentrate grade for Idaho Mine and Brunswick Mine was 3.6 oz/ton and 4.2oz/ton, respectively.


Gold recovery details for the I-M Mine are displayed in Table 1.

Summary


·

Gold recovery from the I-M Mine is reported in detail from the processing of large amounts of mineralized material.

·

The I-M Mine achieved an average total gold recovery of 96.3% during the period from 1936-1941.

·

Gold recovery by gravity methods was reported to be high with an average of 70.1% of gold recovered.

·

The Company believes that technological advances in modern gravity processing equipment might further improve on the amount of gold recovered by gravity methods.

·

Historic flotation concentrates are of attractive grades with an average gold content of 3.9oz/ton (134gpt).

·

Virtually all gold is free milling as demonstrated by the leaching of flotation concentrates and tailings by the mine during past production.



The Company is currently finalizing its work on the geological model and exploration targets at the I-M Mine and expects to provide further information and updates to its shareholders over the coming weeks.



Benjamin Mossman, P.Eng is the qualified person who has verified the historical metallurgical data disclosed in this news release.


Detailed production, processing, and metallurgical data available from the internal records of the Idaho Maryland Mine are available for the period from 1936-1941. Internal mill reports were completed by the operator on a daily, monthly and yearly basis. Metallurgical data was reconciled by the operator to bullion sales. The metallurgical data from the internal documents was transcribed from the monthly reports and reconciled to the annual reports. In general, the Idaho Maryland Mines Co. appears to have been a well-run company with excellent record keeping. It is believed the entire record of mill reports is contained in the library of documents.
