Orosur Mining Inc. ("Orosur" or "the Company") (TSX/AIM: OMI) the South America-focused gold producer, developer and explorer is pleased to report new results from the ongoing step-out drill program at its 100% owned high grade Anzá project in Colombia. These are the last drill holes (MAP_63 to MAP_71) from the APTA target in this exploration campaign, with a further five drill holes planned and currently underway at Charrascala, a highly prospective and untested target within the broader Anzá land package.

 

HIGHLIGHTS

 
 
    -- Orosur's APTA geological model and understanding has improved and been 

validated by current drilling

 
    -- Drilling has extended the mineralized zone a further 95m down dip, to 

a total depth of 400m

 
    -- In the South of APTA, mineralization has been recognized at lower 

depths

 
    -- APTA mineralization remains open along strike and at depth 
 
    -- Notable MAP_70 drill intercepts including: 

9.62g/t Au over 6.0m9.42g/t Au over 7.0m23.66g/t Au over 1.0m5.28 g/t Au over 12.0m

 

Ignacio Salazar, CEO of Orosur, said:

 

"We are delighted with progress in Colombia. Drilling results at APTA continue to extend the mineralized area, while also remaining open along strike and at depth, resulting in a drill tested and improved geological model for follow-on drilling campaigns.APTA represents only 10% of the land base of the Anzá project, which covers over 200km² and contains four additional gold targets.We are excited to be drilling Charrascala at present and look forward to testing the broader potential of our additional targets over time."

 

Notable results to date from new drilling includes 20 intercepts from 4 diamond core drill holes focused on expansion drilling at the APTA deposit. These are highlighted below and include numerous significant intervals at high grades, including:

To date, Orosur has completed 18 holes (MAP_54 to MAP_71, Fig. 2) at APTA totaling 6,314m of drilling. Assay results for the first 9 holes were published in the press release dated February 20, 2018. Significant results of the remaining 9 holes at APTA are included in the table above.

 

MAP_70 Highlights

 

Throughout this exploratory drilling campaign, Orosur's geological understanding has increased and the geological model updated. As a result of this increased geological confidence, MAP_70 was drilled, towards the central northern portion of the APTA deposit, with the aim of testing both the spatial orientation of the mineralized structure and its continuity down dip. The hole was successful on both objectives, with results demonstrating that the mineralized body in this sector of APTA dips to the east. As a result, continuity along strike can now be more accurately tested by future drilling. Additionally, MAP_70 demonstrates that high-grade gold mineralization extends a further 95 meters down from what was previously the deepest hole in the sector (MAP_60) resulting in a vertical continuity of high-grade gold mineralization in the area for over 400m while remaining open at depth.

 

Geological interpretation of hole MAP_70, confirming the mineralized structure to be east-dipping, opens up a new set of opportunities at the southern part of APTA, where such interpretation was previously not established.

 

Figures 1 and 2 below show the cross-section locations, body geometry, grade and correlation with adjacent previous drilling.

Near Term Exploration Program

 

The Anzá project contains four additional high priority targets with coincident geochemical and geophysical anomalies (Fig. 3). After APTA, the next highest priority target at present is Charrascala, which is located approximately 1.5 km to the west of APTA. Charrascala is defined by an extensive coincident gold in soil and magnetic anomaly that is approximately 3 km north-south by 1 km east-west and localized along a potential north-south structure. Surface mapping and sampling combined with interrogation of geophysical data sets share similar attributes to APTA.

 

Given the continued validation of APTA's geological model by recent drilling, the last phase of this current exploration campaign is focusing on Charrascala with the aim of demonstrating the larger mineral potential of the broader Anzá project. To date, Orosur has completed three drill holes at Charrascala and plans to drill a further two in this campaign, for a total of five holes. Assay results of these five drill holes are expected to be received during May 2018 and announced shortly thereafter.

Quality Control and Reporting Protocols

 

This initial drill program recovered HQ/HQ3 core which was logged, split in half for sampling, with the remainder stored for reference in the secure core facility at Finca El Vergel, Anzá, Antioquia, Colombia. Samples are delivered to SGS lab and ALS lab both in Medellín, Antioquia, Colombia (ISO/IEC 17025), for analysis. At the Laboratory, samples are analyzed for gold by traditional fire assay with atomic absorption finish, with those samples returning >5 g/t gold repeated using a 50g aliquot and gravimetric finish. Samples are also analyzed for multi-elements including silver, cobalt, copper and zinc by total digestion ICP at the same labs. Selected samples will also be re-assayed by metallic sieve methods using up to a 350 g aliquot, based on gold and sulfide content.

 

Drill program design, Quality Assurance/Quality Control ("QA/QC") and interpretation of results is performed by qualified persons employing a QA/QC program consistent with NI 43-101 and industry best practices. Standards, duplicates, and blanks are added at the lab as well as standards, blanks and duplicates submitted as unknowns by the Company every ten samples. Approximately 5% of sample pulps are sent to secondary laboratories for check assay.

 

Assays are reported as composited intervals using length weighted averages, with highly enriched zones reported separately. Assays are uncut at this time. Applicable true widths are determined by ongoing investigation of the continuity and geometry of zones and are typically expected to be 65% to 85% of the reported core lengths.
