Angold Drills 248 Metres at 0.75 g/t in Step-Out Hole at Dorado
Angold Resources Ltd. (OTCQB: AAUGF) announced promising assay results from five drill holes at the Lajitas area of its Dorado project in Chile's Maricunga belt. Highlights include:
- 248 m at 0.75 g/t Au from hole DO-21-03.
- 30 m at 1.24 g/t Au from hole DO-21-02.
- 84 m at 0.40 g/t Au from hole DO-21-04.
The results extend mineralization by 80 m, confirming a vertical extent of over 400 m. Further drilling is planned for 2021, testing new targets and expanding known mineralization zones.
- Drilling results confirm gold mineralization over at least 400 m depth.
- Significant mineralization extended 80 m to the northeast from previous results.
- Assays from holes indicate potential for increasing grade at depth.
- Drill holes DO-21-05 and DO-21-06 encountered issues, resulting in lost targets.
VANCOUVER, BC, May 25, 2021 /PRNewswire/ - Angold Resources Ltd. (TSXV: AAU) (FRA: 13L1) (OTCQB: AAUGF) ("Angold" or the "Company") is pleased to announce that it has received further assay results for five holes from the Lajitas area at the Company's Dorado project in the Maricunga belt of Chile.
Key Highlights
Lajitas Drilling Results:
- 248 m at 0.75 g/t Au beginning at 168 m in hole DO-21-03
- 30 m at 1.24 g/t Au beginning at 408 m in hole DO-21-02
- 84 m at 0.40 g/t Au beginning at 166 m in hole DO-21-04
Significant Step-Out: Results from the upper portion of hole DO-21-03 have extended mineralization 80 m to the north-east from DO-21-01 which intersected 302 m at 0.71 g/t Au beginning at surface (see news release dated February 16, 2021).
Extensive Mineralization: Gold mineralization at Lajitas has now been confirmed over a vertical extent of at least 400 m beginning from surface, in deeper portions and between the East and West Zones.
Open in Multiple Directions: This first phase of drilling in the Lajitas area has both confirmed historical work and expanded the zones of mineralization which still remain open in multiple directions and warrant significant drilling.
Assays Pending and Further Drilling Scheduled: Results are pending for 3 additional holes and the Company is planning a significant second drill program for later in 2021. Infrastructure remains at site for further 2021 drilling.
Undrilled Targets Remain: The recently identified Lajitas South target features multiple overlapping anomalies consistent with other major deposits in the Maricunga Belt and will be drilled later in 2021.
Angold's CEO, Mr. Adrian Rothwell, stated: "Results from drilling continue to confirm continuous mineralization, with long intercepts, and new zones. By stepping out from historic mineralized zones with core holes, we have improved our understanding of the potential size of, and controlling structures at, Lajitas. Discovery of mineralization at Lajitas South also confirms the possibility of multiple deposits. The Dorado project certainly has the potential to be a major deposit in the region."
Drilling Context and Geology
Together, these drill holes demonstrate depth and strike continuity of the mineralization at Lajitas. Additional holes are planned to test extensions of mineralization at depth and along strike to the northeast and southwest (Figures 1 and 2).

Gold values are consistently controlled by the presence of both porphyry-style and epithermal-style veins. The presence of two distinct types of gold-bearing mineralization in the Lajitas deposit expands the scope of exploration on the project, providing multiple deposit types to target.
Gold mineralization in all drill holes is controlled by the presence of both porphyry-style and epithermal-style veins. Porphyry-style veins consist of banded quartz veins with variable amounts of magnetite, typical of Maricunga-type gold-copper porphyry systems. Epithermal-style veins also carry gold in the Lajitas drilling; these veins are dominantly quartz and show textures such as colloform and crustiform banding indicating formation at lower temperatures and shallower depths in an epithermal setting. Epithermal veins overprint and came later than porphyry veins.
Targeting is currently underway for expansion of the Lajitas deposit and evaluation of other mineralized settings on the Dorado project.
Assay results from holes DO-21-07 through DO-21-09 are in progress (Table 2).
DRILL RESULTS
Drill hole DO-21-02 was drilled from east to west and intersected mineralization in an area below previous drilling between the West and East zones of mineralization, suggesting potential for additional tonnage in this area (Figure 2). This intercept was extended by 24 m and now encompasses 30 m grading 1.24 g/t Au. The higher grade of this deeper intercept compared to surrounding drill results is encouraging for the prospects of increasing grade at depth in the deposit. Some assayed grades were up to 4.06 g/t gold (over 2 m). See the Company's news release dated March 16, 2021.
Drill hole DO-21-03 was drilled from northwest to southeast below holes DO-21-01 and DO-21-02, and extended mineralization to the northeast and at depth beyond historical drilling. The hole was also intended to refine the structural trend of mineralization, and confirmed mineralization to have a prominent northeast trend, with good depth potential: these new results add 108 m below the interval previously reported.
Drill hole DO-21-04 was drilled from east to west to verify historical data in nearby holes and to test the depth extension of the West Zone of mineralization. In addition to 84 m @ 0.40 g/t Au in the East Zone, the hole intersected two intervals of mineralization in an area previously undrilled between the West and East Zones of mineralization, and approximately 80 m below previous drilling. Like hole DO-21-02, these intervals suggest additional tonnage of mineralization between the two zones.
Intended to test the depth extensions of both the West and East Zones, drill holes DO-21-05 and 05A were drilled from west to east. Although both holes were lost in a fault zone with swelling clays, the combined assays from the two holes confirmed near-surface oxide mineralization in this area. Similarly, hole DO-21-06 encountered the deeper portions of this same fault and did not reach its intended target, the southern and depth extensions of the West and East Zones.

QAQC Statement
All of Angold Resources' drill sample assay results have been independently monitored through a quality assurance/quality control ("QA/QC") protocol which includes the insertion of blind standard reference materials, blanks, and duplicates at regular intervals. Logging and sampling of the Dorado drill samples were completed at Angold's core handling facilities located in Copiapo, Chile. Drill core was diamond sawn on site and half drill-core samples were securely transported to ALS Laboratories' ("ALS") sample preparation facility in Copiapo.
Gold content was determined by fire assay of a 50-gram charge with atomic absorption finish (ALS method Au-AA24). Thirty-three other elements were analyzed by ICP methods with four-acid digestion (ALS method ME-ICP61m). ALS Laboratories is independent of Angold Resources and its facilities are ISO 17025 accredited. ALS also performed its own internal QA/QC procedures to assure the accuracy and integrity of results. Parameters for ALS' internal and Angold's external blind quality control samples were acceptable for the samples analyzed. Angold is not aware of any drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of its drill results data.
