Quinchia gold drilling program to kick off
New gold target identified 200m north of existing Tesorito drilling
HIGHLIGHTS
-
~2500m diamond drilling program to start in July - initially via conventional drilling service provider, transitioning to own rig that has recently been ordered
-
Company’s own diamond drill rig and ancillary equipment expected to arrive in Colombia in October to expand the drilling program
-
Drilling to target:
-
Wide zones of near-surface porphyry mineralisation to confirm prior best intersection of 384m @1.01g/t Au from 16m[1]
-
Higher grade porphyry-style gold intersections at Tesorito such as: 64m @ 1.67g/t Au in TS-DH-07[1] ; and 29.3m @ 1.9g/t Au TS-DH-02[1] ; and
-
a new gold-molybdenum soil anomaly 200m north of previous Tesorito drilling
Los Cerros Limited (ASX: LCL) (Los Cerros or the Company) is pleased to advise that it has commissioned its next drilling campaign on schedule with an anticipated start date of last week of July. The ~2,500m diamond drilling program will commence at the Tesorito porphyry before moving to targets at Chuscal and Miraflores, all located within the Company’s Quinchia Gold Project in Colombia.
All seven (7) previous holes drilled to date have successfully intersected porphyry-style gold mineralisation, including impressive intercepts, such as:
-
384m @ 1.01g/t from 16m incl 29.3m @ 1.9g/t Au from 136.75m in TS-DH-02[1] ; and
-
253.1m @ 1.01g/t Au from 2.9m incl 64m @ 1.67g/t Au from 144m in TS-DH-07[1]
All drill holes tested the southern highest grade 250m x 250m region of an 800m long x 350m wide NNE trending gold-molybdenum soil anomaly. Recent infill soil sampling reveals the anomaly comprises two separate higher grade regions, with the northern region untested by drilling (Figure 1). Both higher grade centres are broadly similar in size, with each corresponding to a magnetic high, overprinting E-W trending epithermal veining and porphyry style alteration. The northern centre is poorly exposed but higher in gold and molybdenum values than the southern centre.
The drill program will commence with testing the continuity of wide higher grade intersections (eg. 64m @ 1.67g/t Au and 29m @ 1.9g/t Au in holes TS-DH-02 and TS-DH-07 referenced above), and it is planned to then test the newly defined northern gold-molybdenum soil geochemistry anomaly (Figure 1).

Figure 1 : Tesorito is an at surface gold mineralised porphyry system. The Company’s first hole of the pending drill program will further explore the southern anomalous zone that has already delivered impressive results. The Company is also developing its drilling strategy for the northern anomalous zone defined here by gold and strong molybdenum assays in soil over a magnetic high.
Company owned drill rig status
Los Cerros advises that the Company’s new C5C diamond drill rig (Figure 2) and ancillary equipment is expected to arrive in Colombia around early October. The assets have been purchased under the $2M Los Cerros / Hongkong Ausino ( Ausino ) Strategic Partnership Agreement ( SPA )[2] .

Los Cerros’ Managing Director Jason Stirbinskis commented :
“With full support from Ausino, the Company has decided to commence drilling sooner via a Colombian drilling services provider while we wait for our own equipment to arrive. The intention is to drill at least two ~350m length diamond holes at Tesorito first and then, once we have our own rig with the efficiencies that it should bring, we will tackle more targets across the Quinchia Gold Project.
The encouraging work of our Colombian geologists and international consulting experts has generated a good number of exciting targets to be drill tested. The first two holes will provide additional geological data to fine tune several deeper porphyry targets”.

Quinchia Gold Project
Chuscal and Tesorito prospects are part of the larger Quinchia Gold Project which also comprises Miraflores, Dosquebradas and other established targets and untested areas of interest within the ~7,500ha parcel (Figure 3).
The Miraflores Gold Deposit has an existing Resource of 877,000 Au ounces at 2.80g/t Au and Reserve of 457,000 Au ounces at 3.29g/t Au[3] . The Dosquebradas Deposit has an Inferred Resource of 459,000 Au ounces grading 0.71g/t Au[4] .
With further exploration success elsewhere within the Quinchia Gold Project, leveraging existing mine planning, plant design and approval status of Miraflores (Mining Authority approval of PTO (construction and operation plan)), the ability to fast track towards gold production becomes a compelling opportunity.
