San Lorenzo Intersects 4.5 Meters of 6.52 g/t Gold Including 1.23 Meters Grading 9.54 g/t Gold in Arco De Oro Hole 2

April 09, 2025 at 08:25 AM EDT

CALGARY – TheNewswire - April 9, 2025 - San Lorenzo Gold Corp. ("San Lorenzo" or the "Company") (TSXV: SLG) is pleased to announce assay results from the second hole on its Arco de Oro target gold target. San Lorenzo also provides an update on preliminary results from the third hole drilled on the target. Arco de Oro is located within San Lorenzo’s flagship Salvadora property in Chile.

SAL 02–25

The table below provides the assay results from Hole SAL 02-25:

	Intercept	From (m)	To (m)	Width (m)	Au g/t	Ag g/t	Cu %
SAL 02-25	A	99.0	103.4	4.4	6.52	13.7	0.1
SAL 02-25	including	99.0	100.2	1.2	9.54	25.2	0.17

San Lorenzo’s VP Exploration, Terence Walker commented on the assay results from the Hole SAL 02-25: “we are pleased that the gold values returned from the main vein system fit well into our model and yet again extends the strike length of the Arco de Oro system - by approximately 250 metres to the south-east. San Lorenzo drilling has now intercepted significant gold grades over 1.3 kilometers of strike length and at depths up to 300 metres. The vein system remains open in all directions”.

SAL 03 – 25

San Lorenzo has also received preliminary results from hole SAL 03-25 – the third hole recently drilled on the Arco de Oro trend. Significant and anomalous gold values were returned over an unexpectedly wide interval. However, those values were wide spaced and intermittent. As a result, San Lorenzo has decided to initiate a detailed field investigation prior to releasing assay information which may be unreliable. Preliminary indications are that SAL 03-25 was drilled within and across a fault zone which has caused the system, visible from surface workings to extend for at least another 2 kilometers, to have been laterally displaced in the vicinity of hole SAL 03-25. A coherent vein, like those in surface and underground workings and all other Arco de Oro drill holes, was not intercepted in hole SAL 03-25.

San Lorenzo will start an IP survey to expand geophysical coverage at both Arco de Oro and Cerro Blanco immediately, which will be closely followed up by the next phase of drilling. Details will be provided in an upcoming news release.

Sample Acquisition, Handling, Analysis and Qualified Person

All drill core logging, sample selection and cutting, followed by bagging and delivery of 50% of the HQ core to the ALS lab in Copiapó, was carried out by San Lorenzo staff under the on-site supervision of Eric Hanson P. Geo. or Terence Walker, P. Geo., each a “qualified person” for purposes of NI 43-101. All assays were conducted by ALS Patagonia Limited. Samples were crushed and screened to -80 mesh and analyzed using their multi-element ICP after aqua-regia digestion. Gold was analyzed by fire assay atomic adsorption. ALS included standard check sampling techniques including blank and duplicate insertions.

Terence Walker, P. Geo. and QP, has reviewed and approved the contents of this release.

About San Lorenzo

San Lorenzo is focused on advancing its flagship Salvadora property located in Chile’s mega-porphyry belt. Results obtained from drilling programs already conducted on 4 different targets have convinced management that several significant gold and copper enriched epithermal and porphyry style systems lie within the boundaries of the Salvadora property.
