Correction: Endomines Ore Reserve and Mineral Resource Estimate update
Endomines AB, stock exchange release 23 April 2019 at 07:30 CEST
This is a correction to Endomines stock exchange release issued on April 9, 2019 at 13:00 CEST regarding Endomines ore reserve and mineral resource update. In the table presenting Mineral Resources – Karelian Gold Line, figures for the Pampalo Inferred Total and Karelian Measured + Indicated Total for kg and grade (Au g/t) were not correct. Please find below the original stock exchange release with the correct tables.
Endomines is pleased to announce its 2019 gold reserve and resource estimates for its Pampalo mine and the resources along the Karelian Gold Line in Finland, as of 31 December 2018, and the gold resource estimates for its gold projects in Idaho, USA.
Gold resources at the Pampalo mine and resources along the Karelian Gold Line in Finland
The Pampalo mine depleted the remaining reserves during 2018. The 2017 mineral resources at Pampalo, restated herein, have been defined by a 5,040-meter drill program targeting the deep extension area and are estimated to contain 16, 611 ounces gold in indicated and 20 341 ounces gold in inferred resources. As the current gold prices do not support the capital investment required to advance the decline for access to the resource, the Pampalo mine was placed on care and maintenance in October 2018.
There have been no changes in the reported mineral resources for other deposits along the Karelian Gold Line except for the Pampalo East project where the remaining ore reserves (32,000 tonnes) have been converted back to mineral resources. The measured and indicated resources along the Karelian Gold Line total an estimated 56,204 ounces and the inferred resources 70,453 ounces gold.
For the Pampalo mine and the resources along the Karelian Gold Line in Finland, the estimates have been prepared according to the 2012 Australasian Code for Reporting of Mineral Resources and Ore Reserves (Joint Ore Reserve Committee - JORC-code).
Gold resources in Idaho, USA
During the past year, Endomines continued to improve its understanding of the Idaho gold projects that in acquired in February 2018. Endomines is working to develop its Friday Underground mine and to convert a portion of the estimated 97,200 measured and indicated resource ounces into mineral reserves. Inferred resources at Friday amount to 46,700 ounces of gold.
In 2018, the historic data and information for the Buffalo Gulch project was validated and converted to a measured and indicated mineral resource of 114,700 ounces gold. Similar conversion of the historic resources at Deadwood are also targeted. Additionally, the Company is working toward developing mineral resource estimates for its Kimberly and Rescue projects through exploration programs targeting known high-grade gold and silver vein systems.
The mineral resources currently quoted regarding the Deadwood, Rescue, and Kimberly exploration projects, are per definition historical, made before the introduction of today’s disclosure standards. Endomines cautions that while the presented historic resources for Kimberly, Rescue, and Deadwood appear to be in general accordance with those set out in NI 43-101 Sections 1.2 and 1.3, a qualified person has not done sufficient work to classify the historical estimates as current mineral resources, and Endomines is not treating the historical estimates as current or reliable.
The mineral resources reported for the Friday Underground and Buffalo Gulch projects in Idaho, USA, are classified in accordance with standards defined by Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”), “CIM Definition Standards - For Mineral Resources and Mineral Reserves”, prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council on May 10, 2014.

| *Notes: |
| (1) Measured, Indicated and Inferred mineral classifications are assigned according to CIM Definition Standards. Mineral resources, which are not mineral reserves, do not have demonstrated economic viability and there is no guarantee that mineral resources will be converted to mineral reserves. Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding. |
| (2) The mineral resource estimate was prepared by HRC based on data and information available as of March 1, 2016. The Measured, Indicated and Inferred mineral resources are reported considering a base case estimate that applies a cutoff grade of 3.4 g/t Au based on the estimated operating costs, recoveries, and a $1,300/oz gold price. |
| (3) The mineral resource estimate was prepared by HRC based on data and information available as of December 10, 2017. The Measured, Indicated and Inferred mineral resources are reported considering a base case estimate that applies a cutoff grade of 0.14 g/t Au based on the estimated operating costs, recoveries, and a $1,300/oz gold price. |
| (4) Mineral Resources captured within the pit shell meet the test of reasonable prospect for economic extraction and can be declared a Mineral Resource. Pit optimization is based on assumed gold price of US$1,300/oz. and mining, processing and G&A costs of US$15.20 per ton processed Metallurgical recoveries for gold are 90%. |
| (5) Endomines caution that while the historic resources presented appear to be in general accordance with those set out in NI 43-101 Sections 1.2 and 1.3, a qualified person has not done sufficient work to classify the historical estimate as current mineral resources, and Endomines is not treating the historical estimate as current nor reliable. |
