Looks like they are building the launch control centre at an old cement factory called Punta Indio. Punta Indio also has a test stand (this might be a launch complex as well). Launch complex is at Bahia Blanca. Some Tronador II information.

Height: 27.8 m
Diameter: 2.5 m
Launch Mass: 64 t
Payload: 250 kg

The video shows launch of either VEx 1A or VEx 1B (probably 1B, since that was successful). An out of date schedule is shown. A vehicle is shown being assembled. This is probably VEx 5A.

Some highlights from the video:
They have decided to move all manufacturing and testing to Punta Indio, with a simple HIF at Puerto Belgrano.
They will use structural tanks with friction stir welding for the Tronador II fuselage.
The engine test benches will also be housed in Punta Indio.
They will have two sites, actually. One for the test launches of the VEX, and another for the factory.
They will develop their own composite pressure vessels (400Bar) for the pressurizers. Also development of spherical tanks.

In the absence of climatic inconveniences in the Samborombón Bay area, the launch of the VEX-5A Experimental Vehicle is scheduled to take place from 22 to 24 November.

The VEX 5-A rocket test of the Tronador II space project was suspended for "technical" reasons only a few minutes before launch from the Punta Indio space base, the National Space Activities Commission reported.

For those of us who don't understand Spanish.

"#CoheteTronador el Vex5a would be released in the coming days after suspending the launch scheduled for yesterday #PuntaIndio"

The third prototype of the Tronador, on Wednesday, returning to the Indian Point Base after the suspension of the launch. The CONAE would be to try again before Christmas.

This Tronador project has always moved slowly. And the present government seems to have limited the funds available for the local space related activities.

Vex5a failed. At least Argentina´s first kerolox engine was able to work for some seconds of flight

Bing Translation.

"April 20, 2017, being approximately 18:00 hs, was the experimental VEX5A vehicle testing, the line of development of the satellite launcher national TII-TIII.

The behavior of all subsystems of flight and ground segments were 100% in accordance with the design, from ignition to eight seconds.

Thus the takeoff and subsequent period of flight were nominal. For reasons still under analysis within six seconds of flight was interrupted the supply of propellant to the engine."

Well, foo ... hate to see that happen.  Hope the pad isn't badly damaged, and that they find & fix the problem quickly.  Best wishes for the next one!

According to this site it didn't have much propellant in it at launch, and almost all of it was RP-1 and LOX: http://www.b14643.de/Spacerockets_1/Rest_World/Tronador-LSA/Description/Frame.htm.

That's 0.5% of what the Falcon 9 that blew up on the pad had in it, for reference.
