New Mapping Program At Central Mine Area Of Pamlico Project

VANCOUVER - Newrange Gold Corp. reported that a new mapping and sampling program in the historic Central Mine area of its Pamlico Project in Nevada has indicated widespread gold mineralization with values up to 47.34 g/t.  In keeping with the renewed focus on the larger scale geological setting, and as there is little historical information from the mine itself, a preliminary program of mapping mineralized structures and sampling dump material from the numerous adits was undertaken to determine what had been mined in the past.  

Gold mineralization seems to have been confined to a volcano-sedimentary (VS) unit on the west side of a limestone ridge.  A total of 67 grab samples were taken of quartz breccia material (most with iron oxides) in the old mine dumps extending over an area of approximately 700 meters north-south by up to 350 meters east-west.  Of these samples, 55 (78%) returned gold values greater than 0.1 g/t, 29 samples (43%) were greater than 1.0 g/t and 13 (19%) assayed more than 5.0 g/t Au.  The average grade of all 67 samples was 4.33 g/t gold.

“These results are very encouraging in that they give us a better understanding of the style of mineralization in the Central Mine area,” said, Robert Archer, President & CEO. “As the area had not been previously mapped in detail, the new information will be important for our follow up drilling.  The ‘91’ Zone discovered by Newrange in late 2020 lies just on the eastern edge of here at a vertical depth of approximately 100 meters.  Although we do not have any reliable production figures from the mine, the lateral extent and tenor of the polymetallic mineralization in the old dumps coupled with that in the ‘91’ Zone suggests that a significant mineralizing system is present here. The Chargeability anomaly named the ‘Line 5’ anomaly lies just to the east, under the limestone ridge.  It is still considered likely that this anomaly reflects sulphide mineralization within the VS unit below the limestone.”

The gold-bearing mineralized structures at the Central Mine are sub-parallel with a general north-south strike and dip between 15 and 85 degrees to the east and are offset by east-west faults.  The structures contain quartz veins (including banded quartz), silicified vein and fault breccia, and variable amounts of iron-oxides.  Veins are between 4 centimeters and 2 metres wide.  Limonite, pseudomorphs of pyrite by goethite and boxwork textures all indicate that sulphides were present in the quartz veins prior to oxidation.  Copper minerals were noted locally.

In addition, recently recognized skarn alteration and extensive silicification exists in the limestones to the immediate southwest of the Central Mine area, which fits with the working hypothesis that mineralization on the Pamlico Project is related to a large intrusive system.
