Past mining, historic drilling, and the Company's previously completed Phase One and Phase Two drilling programs had outlined significant oxide domain gold and silver resources (Canadian NI 43-101 compliant) west of the Calvada open pit that remain open along strike and down-dip. The four drill holes reported herein, totaling 883 metres, targeted these potential extensions to gold and silver resources. Highlights include:
38.1 metres grading 0.87 g/t Au and 2.5 g/t Ag (0.89 gpt Au Eq) of oxide metallurgical domain mineralization in drill hole CAL23-004R including 10.6 metres grading 2.02 g/t Au and 2.4 g/t Ag (2.04 gpt Au Eq). This drill hole, coupled with earlier Lahontan drill results, shows that oxide gold and silver mineralization extends in a westerly direction from the Calvada pit along the Calvada Fault, a key target area for resource expansion.
82.3 metres grading 0.68 g/t Au and 2.0 g/t (0.70 gpt Au Eq) of oxide metallurgical domain mineralization in drill hole CAL23-001R, including 21.3 metres grading 0.93 gpt Au and 1.9 gpt Ag (0.95 gpt Ag). This thick intercept should help expand the scale of the conceptual pit shell used to constrain mineral resources in future resource estimates. This intercept also contains a higher-grade interval which may be indicative of the margin of a 'feeder' structure. Oxide gold and silver mineralization remain open below CAL23-001R generating yet another target for resource expansion at the Santa Fe Mine.
The plan view and cross section of the Calvada pit area (above) highlights the resource expansion potential of the current drilling campaign. All four drill holes intercepted significant oxide gold and silver mineralization, expanding the footprint of the Calvada resource to the west. Mineralization remains open to the west, east and at depth and will be the subject of additional drilling during 2023.
QA/QC Protocols
Lahontan conducts an industry standard QA/QC program for its core and RC drilling programs. The QA/QC program consisted of the insertion of coarse blanks and Certified Reference Materials (CRM) into the sample stream at random intervals. The targeted rate of insertion was one QA/QC sample for every 16 to 20 samples. Coarse blanks were inserted at a rate of one coarse blank for every 65 samples or approximately 1.5% of the total samples. CRM's were inserted at a rate of one CRM for every 20 samples or approximately 5% of the total samples.
The standards utilized include three gold CRM's and one blank CRM that were purchased from
As part of the RC drilling QA/QC process, duplicate samples were collected of every 20th sample interval at the drill rig to evaluate sampling methodology. Samples were collected from the reject splitter on the drill rig cyclone splitter. Samples were collected at each 95- to 100-foot (28.96 - 30.48m) mark and labeled with a 'D' suffix on the sample bag. No duplicates were submitted for core.
All drill samples were sent to
