Sable Announces Positive Drill Results from Don Julio Drill Program






South32 Agrees to up to 7,000 metres for Second Drill Phase •


Sable Resources Ltd. (TSX-V: SAE) (OTCQB: SBLRF) is pleased to announce positive drill results from the drilling program undertaken at the Don Julio Project, located in San Juan Province, Argentina during the months of January through June. Based on these results, the Company plans to initiate a second phase drill program under the current Earn-In agreement with a wholly-owned subsidiary of South32 Limited at the Don Julio Project. The second phase drill program approved by South32 and Sable comprises a minimum of 5,000 metres, expandable to 7,000 metres depending on results. Sable plans to start the program immediately following the end of the Argentine winter in October. The principal objective of the next drilling campaign is to continue testing the La Gringa and Punta Cana porphyry targets following the encouraging results from the first phase drill program.


The results of the 4,294 metres drilled during the first half of 2022 confirmed the presence of Cu-Au-Mo porphyry style alteration and mineralization associated with the over 5 km long lithocap that extends from La Gringa on the northwest to Poposa on the southeastern limits of the lithocap. Both the proximal alteration at La Gringa and the porphyry phases intercepted at the Punta Cana porphyry reported long anomalous intercepts. The porphyry mineralization discovered at Don Julio and its associated advanced argillic alteration are part of the 6-10 Ma Andean mineral belt that hosts world class Cu-Mo-Au porphyry deposits south of Don Julio and Au-Ag high sulfidation deposits to the north.


“Proving for the first time the transition from advanced argillic alteration into porphyry style mineralization is very significant for the Don Julio Project, which has been explored for over 20 years by multiple companies, including four years of systematic work by Sable. We are in the right Miocene mineral belt and within a project area with multiple mineral centres that define a footprint of more than 100 km2,” stated Ruben Padilla, President and CEO of Sable, who added, “We appreciate the financial and technical support of South32 during the initial drill program and its support to continue drilling to search for higher grade zones within the concealed porphyry stock at La Gringa, and unexplored parts of the Punta Cana porphyry system.”

Geology and Holes Description


Punta Cana


The Punta Cana porphyry is the most recent discovery of Sable’s geology team. It consists of discrete outcrops of different phases of diorite dykes hosting A, B, and Maricunga-type veinlets with surface values up to 3 g/t Au, and 0.6% Cu, within a heavily covered terrain. Holes DJ-DH-22-06 and DJ-DH-22-08 were collared from the same pad with different angles targeting the zones with better grades in surface samples. Hole 06 started in poorly mineralized diorites and intrusion breccias only showing minor Maricunga veinlets and then entering better mineralized phases with better defined biotite alteration after 250m depth where the best grades of Au-Cu are observed. Hole 8 started similarly than hole 06 with scarce mineralization in the first 120m and then going into a medium grained diorite with Maricunga and A-type veinlets containing magnetite, chalcopyrite, and trace bornite. General alteration consists of chlorite, illite, and weak biotite; both holes are affected by carbonate-pyrite likely associated with Intermediate Sulfidation events that seems to introduce significant values of silver to the Au-Cu mineralization. Hole 08 sits on the margin of a large magnetic anomaly that will be tested next season looking for earlier and higher-grade intrusive phases. Two more holes (DJ-DH-22-04, 05) were drilled targeting a diatreme breccia zone 500m north of the porphyry and did not return anomalous values.


La Gringa


La Gringa is located on the northern extreme of the Miocene lithocap that characterizes Don Julio. Two holes were drilled following a structural, alteration, and geochemical vector towards the west. Hole 07 successfully went from strong advanced argillic alteration into well-defined sericitic and finally into biotitic alteration. B and A type porphyry veinlets are observed almost from the beginning of the hole but become more frequent and Mo bearing around 450m. Hole 09 was drilled 480m NW of hole 07 and intercepted similar geology reaching biotite alteration around 500m depth; significant molybdenite and minor chalcopyrite mineralization was observed accompanying the porphyry veinlets within the sericitic and biotite zones. Both holes intercepted almost exclusively Carboniferous sediments (sandstone-siltstone) with only minor dacite dykes; the biotite alteration within the sediments is considered proximal to the causative porphyry stock. Searching for such concealed stock will be the focus of the next campaign at La Gringa. Sable notes that full assays for hole DJ-DH-22-07 have not been received, the intercepts shown correspond to the top and bottom parts of the drill hole with the mid section (285 samples) still being analyzed by ALS Minerals.




The Poposa target is located on the southwest margin of Don Julio lithocap. Three holes were drilled in this area (DJ-DH-22-01, 02, and 03) targeting concealed porphyry mineralization beneath the outcropping advanced argillic alteration. Although the three holes had stability issues and had to be stopped before reaching the targeted depth, all of them showed transition from advanced argillic into sericitic alteration as well as A and B veinlets towards the end of holes 01 and 02. Along the section shown in Figure 4 gold values were as high as 1.8 g/t Au, 1.96% Cu; and 69 ppm Mo. Poposa is located 4km South of La Gringa target and it is considered to represent a different porphyry center, the target remains open for future drilling.


Porphyry mineralization is characterized by broad zones of disseminated sulfides and vein stockwork, therefore true width cannot be determined at this time. Maps and tables associated with this press release will be available on Sable’s website ( Mineralization at La Gringa target seems to represent a traditional Cu-Au-Mo porphyry and therefore results are presented as copper equivalent (CuEq) or individual Cu, Mo values. The Punta Cana porphyry shows affinity with Au-rich porphyry systems typical of the Maricunga belt, containing Au, Cu and significant amounts of Ag, Zn; results for Punta Cana are presented in gold equivalent (AuEq). CuEq and AuEq were calculated based on 100% recovery and prices of USD 1,500 per oz for gold; USD 18.0 per oz for Ag; USD 3.0 per pound for copper; and USD 10.0 per pound of Molybdenum. Although Zn is highly anomalous at Punta Cana it was not included in the calculations.

The Don Julio project comprises 69,350 hectares in the Cordillera Frontal in San Juan, Argentina. It includes the Don Julio cluster that contains numerous targets of porphyry (La Gringa, Poposa, Amarillo, Punta Cana, Tocota); intermediate sulfidation (Lodo, San Gabriel, Colorado); skarn (Fermin); and the regional properties that include the Los Pumas project as well as extensive unexplored ground. Since 2018, Sable has conducted systematic surface work including mapping, rock sampling, talus sampling, ground and UAV magnetometry, and induced polarization. Sable also performed a first drilling campaign in 2019 with 3,101m drilled in 11 holes targeting high-sulfidation mineralization. In 2021, Sable signed an Earn-In agreement with South32 to jointly explore the Don Julio Project.




Sable is a well-funded junior grassroots explorer focused on the discovery of new precious and base metal projects through systematic exploration in endowed terranes located in favorable, established mining jurisdictions. Sable’s focus is developing its large portfolio of new Greenfields projects to resource level. Sable is actively exploring the San Juan Regional Program (163,969 ha) incorporating the Don Julio, El Fierro, La Poncha, and Los Pumas Projects in San Juan Province, Argentina; and the Mexico Regional Program (1.16Mha in application, 39,000ha titled) incorporating the Vinata and El Escarpe projects.
