STOCKHOLM--(BUSINESS WIRE)--Regulatory News:
Endomines is pleased to announce results of the 2012 drilling campaigns at its Korvilansuo and Rämepuro properties located at Karelian Gold Line, Eastern Finland. Drilling campaign at Korvilansuo aimed to increase geological understanding and increase resources of the deposit. Drillings at Korvilansuo property has intersected gold mineralization represented by core sections from a couple of metres up to almost 50 metres in length with encouraging results. The drilling at Rämepuro was aiming to provide additional information from the areas where the information was less dense. Both campaigns succeeded well in their goals.
KORVILANSUO
Korvilansuo is located on the Karelian Gold Line, near Ilomantsi, in Eastern Finland and the mineral rights of the property are fully owned by the Company. Finnish authorities have within the last weeks granted new claims for the next 5 years over the whole target area.
The 2012 core drilling campaign at Korvilansuo was aimed at extending and verifying the gold mineralization discovered during the 2011 campaign, with a total of 3905 m of diamond drilling completed. Previously unpublished intercepts include:
- 49.6 m @ 2.1 g/t gold
- 20,5 m @ 4.6 g/t gold
- 16.9 m @ 5.3 g/t gold
- 14.8 m @ 4.6 g/t gold
- 12.3 m @ 1.3 g/t gold
- 8.0 m @ 2.4 g/t gold
- 7.0 m @ 4.1 g/t gold
- 6.6 m @ 2.1 g/t gold
- 6.3 m @ 3.0g/t gold
- 6.0 m @ 1.7 g/t gold
- 4.5 m @ 1.7 g/t gold
- 3.3 m @ 21.3 g/t gold
- 3.0 m @ 5.9 g/t gold
- 3.0 m @ 3.6 g/t gold
- 2.7 m @ 10.0 g/t gold
- 2.0 m @ 6.8 g/t gold
“The exploration program in the Korvilansuo-Muurinsuo area is just beginning but all of the results so far obtained support our firm conviction that this area has all the necessary characteristics of Archean greenstone-hosted gold provinces and real potential for growing into a significant and successful gold project”, comments Endomines CEO Markus Ekberg.
Additional 320 more assays are still pending and should be received within the next few weeks. Full exploration results for the Korvilansuo property are tabulated in the appendix.
Korvilansuo, along the Karelian Gold Line in Ilomantsi, is a typical Archaean orogenic gold occurrence, comprising subvertical lodes defined by sulphide disseminations and auriferous tourmaline-quartz veins and breccias. The principal host rocks at Korvilansuo are volcanogenic metasediments which are metamorphosed and altered to chloritic and sericitic schists under transitional greenschist-amphibolite facies conditions and intruded by quartz-feldspar porhyric tonalite dikes. Korvilansuo lies within the N-NE trending Korvilansuo Shear Zone, near the southern end of the Korvilansuo-Kivisuo-Elinsuo-Muurinsuo mineralized zone, subparallel with the contact of the Kuittila tonalite intrusion, which also host gold mineralization. Native gold is irregularly distributed through host rock disseminations and in quartz veins as inclusions in biotite, pyrrhotite, pyrite and arsenopyrite, as free grains up to 1 mm in size between silicates and intergrown with bismuth, tellurides and rutile. Several hundred assays have been additionally checked with 0.5 kg screen fire assay or 500 g cyanide leach procedures so that nugget effects may be clearly distinguished.
Finnish authorities have within the last two weeks granted new claims covering the whole target area for the next 5 years. Korvilansuo and the neighboring areas have thus been covered by recently granted, already existing claims or new claim applications.
The drilling database will as soon as possible be sent to Outotec Oyj for resource estimation and the resource estimate will be published in due course.
RÄMEPURO
Four new exploration holes, totaling 320 m, were drilled at the Rämepuro deposit. The following intersections were received from the assays:
The drilling database has been sent to Outotec Oyj for the resource estimation.
A metallurgical study on mineralized bulk sample taken at the surface of Rämepuro gold deposit has been carried out in September 2012 at the Geological Survey of Finland (GTK) for Endomines Oy. Among other tests, the feasibility of adopting the present Pampalo Mill flow sheet for Rämepuro was tested by down-scaling the flow sheet at the GTK pilot plant.
The metallurgical tests were carried out on 370 t mineralized samples from the Rämepuro deposit. The head grade of the sample was 2.4 g/t gold. The total net energy consumption for grinding in a two-stage ball mill circuit varied from 12 to 13 kWh/t, the latter when finer grinding was applied.
The average gold recovery in the tests was 86.5 % varying from 72.7 % to 92.7 %. The mass percentage of the bulk concentrate (gravity+flotation) was 1.71 wt%. The gold recovery of the shaking table concentrate varied between 30 and 45 %. The average gravity concentrate had a gold grade of 3,502 g/t at a recovery of 38.5 % and the average silver grade was 1,362 g/t at a recovery of 20.3 %.
Samples for an environmental permit application were collected during the pilot plant test run.
Drilling technical and QA/QC procedures All drilling has been carried out by Pöyry Finland Oy, using WL-66 (~NQ2) tubes, resulting in cores of 50.5 mm in diameter. The locations of the drill holes have been surveyed using GNSS-GPS equipment. Azimuth and dip deviations have been measured using the Reflex Maxibor Borehole Survey System.
The preparation and assaying of the half-core samples cut by Endomines have been carried out at the Labtium laboratory in Rovaniemi. Finland. The sample procedure used at the Labtium laboratory was Pb - Fire Assay of 50g subsample and determination of gold using the ICPOES method (Labtium code 705P). Any assay with gold grades exceeding 10 g/t was re-assayed using a 50g Fire Assay method and gravimetric analysis (Labtium code 705G). Control assays have been done for 278 samples with 500 g Screen Fire assay or 500 g Cyanide leach (Labtium code 236A) methods to prevent the nugget effect.
Normal QA/QC (Quality Assurance/Quality Control) procedures have been adhered to on all the samples, with standards blanks and duplicates routinely submitted as part of the sampling program. The quality of sample preparation, security, integrity and chemical assays was equal to, or exceeded current industrial standards and the requirements of the JORC-code.
