    E2 Metals discovers high-grade surface gold at Mia prospect

    E2 Metals (ASX: E2M) has announced the discovery of significant gold at the Mia prospect within its Conserrat project in Argentina.

    The company reported that rock chip sampling at Mia returned significant gold in addition to high silver. Important assays include 43.9gpt Au and 730gpt Ag; 37.4gpt Au and 784gpt Ag; and 23.9gpt Au and 1128gpt Ag.

    E2M said that high-grade gold mineralisation is defined over a 50m strike length and is hosted in a broader northwest and east-orientated vein system that is mineralised over 350m strike length.

    The company noted that the mineralisation is associated with classic epithermal veins displaying banded and bladed silica textures, hosted in quartz and crystal-rich Chon Aike volcaniclastics.

    E2M said that follow up trenching has commenced at Mia to define the limit of the vein system and test for potential blind extensions.

    Conserrat project

    Conserrat is located in the Santa Cruz province of Argentina and is centred along trend from AngloGold Ashanti’s world-class Cerro Vanguardia epithermal vein field and hosts an extensive but partially exposed vein system.

    In October 2019, the Company had announced the discovery of two mineralised vein trends at the Ro and Florencia prospects in the southern project area.

    Mia Prospect

    Mia prospect in the Conserrat Project was discovered by reconnaissance sampling in an area of no prior exploration. Mia is a new vein discovery located 2km southeast of Florencia and 4.7km south of the Veta Blanca-Emilia trend, expanding the footprint of the Conserrat vein field.

    The outcropping veins were discovered by following up first-order silver anomalies in the regional soil (LAG) data. E2M said that additional soil targets exist within the project and regional mapping and sampling is ongoing.

    Mia geology

    Mia hosts a prominent northwest trending vein system mapped over 600m. The vein trend comprises several parallel veins and breccias that outcrop up to 30m apart across strike.

    To the southeast, the northwest veins intersect a second set of east orientated veins. The intersection between the vein sets is coincident with the high-grade gold and silver zone.

    The principal veins are characterised by chalcedony, opaline, and crystalline silica, with weak to moderate limonite (after sulphides). These silica textures form under low hydrothermal temperatures interpreted to occur at higher levels in the epithermal system.

    High grade gold and silver mineralisation are associated with a discrete segment of the northwest vein characterised by crustiform and bladed silica-sulphide textures. These textures are typical of the deeper more mineralised parts of an epithermal vein system and are ubiquitous in all multi-million-ounce gold and silver deposits in the Santa Cruz province.

    Veins similar to Ro and Florencia

    The company noted that all veins at Mia are hosted in quartz and crystal-rich Chon Aike volcaniclastics similar to those observed at Ro and Florencia.

    E2M said that the low temperature silica veins at Mia with modest gold and silver mineralisation are like those defined in drilling to date, with the additional presence at Mia of higher-grade crustiform and bladed silica veins highlighting the potential for higher grade gold shoots at depth within all prospects.

    High-grade results from sampling at Mia

    The company reported that the sampling at Mia comprised an initial 23 rock chip program.

    Key gold and silver results from a high-grade zone with a measured strike length of 50m include 43.9gpt Au, 730gpt Ag; 37.4gpt Au, 784gpt Ag; 23.9gpt Au, 1128gpt Ag; 7.35gpt Au, 11.5gpt Ag; and 6.6gpt Au, 12.3gpt Ag.

    The company noted that the high-grade zone occurs within a mineralised northwest and east orientated vein system with an overall measured strike length of 350m.

    Further significant assay results over the mineralised strike length (beyond the high-grade zone) include 2.34gpt Au, 3.4gpt Ag; 2.11gpt Au, 5.3gpt Ag; and 1.16gpt Ag, 2.5gpt Ag.

    Future plans

    E2 Metals announced that it has mobilised an excavator to the Mia prospect and has commenced a preliminary trench program to determine the extent of the vein system and to test for blind extensions.

    E2M said that the prospect is in an area that has received little exploration and follow-up geophysics is being contemplated to better understand the link between Mia, Florencia and other prospects.

    The company said that the prospect is located within the current Environmental Impact Assessment (EIA) and is cleared for drilling.

    Management comments

    E2 Metals’ Managing Director Todd Williams said: “We are delighted to announce a new high-grade surface discovery within the Conserrat Project. This discovery is the first evidence of bonanza-type gold within the project and is an exciting addition to the significant silver mineralisation intercepted to date at Ro and Florencia.

    The vein textures observed at Mia are similar to many prospects in the project, giving us confidence further high-grade gold discoveries will be made. The Company is well positioned to follow up on these encouraging results and prepare targets for drill testing.”
